Description: The quadrangle straddles urban and rural areas along the Interstate 80 corridor west of Salt Lake City. The map area is in the eastern Basin and Range Province and includes several mainly north-south-trending mountain ranges and intervening valleys and the southern part of Great Salt Lake. Bedrock geologic units from Precambrian to Miocene age are overlain by Tertiary and Quaternary surficial deposits. Geologic structure is related to the Uinta-Tooele structural zone, Sevier orogenic belt, and Basin and Range extension. Surficial deposits are largely related to late Pleistocene Lake Bonneville, Great Salt Lake, and alluvial depositional environments. This map shows the geology of the quadrangle at an intermediate scale (1:62,500). The accompanying map explanation includes an introductory text, geologic unit descriptions, figures, tables, photos, mapping sources, geologic units, correlation charts, geologic symbols, lithologic columns, and geologic cross sections.

Description: The U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Wildlife Resources, collected bathymetric data for the south part of Great Salt Lake during 2002-04 using a single-beam, high-definition fathometer and real-time differential global positioning system. About 7.6 million depth measurements were collected along more than 930 miles (1,690 kilometers) of survey transects. Sound-velocity profiles were obtained in conjunction with the bathymetric data to provide time-of-travel corrections to the depth calculations. Data were processed with commercial hydrographic software and exported into geographic information system (GIS) software for mapping and calculation of area and volume. Area and volume calculations show a maximum area of about 508,000 acres (2,056 square kilometers) and a maximum volume of about 9,257,000 acre-feet (11.42 cubic kilometers) at a water-surface altitude of 4,200 feet (1,280 meters). Minimum water-surface altitude of the south part of Great Salt Lake is just below 4,167 feet (1,279 meters) in the area just south of the Union Pacific railroad causeway halfway between Promontory Point and the western edge of the lake. At this altitude, and continuing up to about 4,176 feet (1,279 meters), the south part of the lake is separated into two areas by a ridge extending from Promontory Point to Hat Island. These data have been published in Baskin, R.L., and Allen, D.V., 2005, Bathymetric map of the south part of Great Salt Lake, Utah: U.S. Geological Survey Scientific Investigations Map 2894, published online at http://pubs.usgs.gov/sims/2005/2894/.

Description: Explanation of PACES Gravity DatasetA set of gravity data is provided for the Dugway Proving Ground map area that was obtained from the Pan American Center for Earth and Environmental Sciences (PACES) at the University of Texas El Paso. We accessed this data from their website in 2012 (PACES, 2012). This is a compilation of data provided from various sources to PACES. Gravity measurement locations are indicated as points. The gravity measurements were adjusted to obtain Bouguer gravity anomalies. The map presents the Complete Bouguer gravity anomaly (CBGA) which is the gravity field anomaly after accounting for variations due to elevation, terrain and latitude; interpolated using a 5 km grid in order to average out inherent, yet minute, differences in the PACES gravity data and contoured at an interval of 1 milliGal (mGal). Local spatial variations in the CBGA field (after correcting for deep crustal structure) reflect the distribution of densities in the mid- to upper crust. Densities often can be related to rock type, and abrupt spatial changes in density commonly mark lithologic or structural boundaries. Lower gravity anomalies generally reflect less dense valley fill deposits (mass deficiency), while higher anomalies reflect higher density pre-Cenozoic rocks (mass excess) exposed within mountain ranges of the map area.

PACES has played a significant role in the compilation of gravity data in southwestern North America. This effort has been conducted in close cooperation with the U. S. Geological Survey, the National Geospatial-Intelligence Agency (formerly the National Image and Mapping Agency), National Oceanic and Atmospheric Administration, industry and academic colleagues. Together, we have developed the GeoNet gravity database portal that provides access to our new database for the U. S. The U. S. Geological Survey Open File report that describes this effort is available at this link: Open-File Report 02-463. The version now available is a major update to existing databases and is now also terrain corrected. This effort is also a key part of our NSF-supported projects to develop a geoscience cyberinfrastructure (GEON and SWGeoNet), and also features a tutorial "Getting Started: Using and Understanding Gravity Data".
The new terrain corrected United States gravity database is available through the GeoNet link below. The terrain corrections were calculated by Mike Webring of the U. S. Geological Survey using a digital elevation model and a technique based on the approach of Donald Plouff. The reduction of these data has been updated with modern geodetic datums and a higher precision digital elevation model. In the present version, latitude and longitude values are referenced to NAD83 (North American Datum 83; horizontal datum) and elevation values in meter are referenced to NGVD88 (Vertical datum).

Description: The quadrangle straddles urban and rural areas along the Interstate 80 corridor west of Salt Lake City. The map area is in the eastern Basin and Range Province and includes several mainly north-south-trending mountain ranges and intervening valleys and the southern part of Great Salt Lake. Bedrock geologic units from Precambrian to Miocene age are overlain by Tertiary and Quaternary surficial deposits. Geologic structure is related to the Uinta-Tooele structural zone, Sevier orogenic belt, and Basin and Range extension. Surficial deposits are largely related to late Pleistocene Lake Bonneville, Great Salt Lake, and alluvial depositional environments. This map shows the geology of the quadrangle at an intermediate scale (1:62,500). The accompanying map explanation includes an introductory text, geologic unit descriptions, figures, tables, photos, mapping sources, geologic units, correlation charts, geologic symbols, lithologic columns, and geologic cross sections.

Description: This data layer consists of National Wilderness Preservation System areas in the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was created by combining the best available data from the federal agency responsible for administration of a given wilderness area. Where larger scale data could not be obtained the National Atlas layer "National Wilderness Preservation System" was used as the data source. In its present form source data varies from a scale of 1:10000 to 1:2,000,000 (see lineage for details on source scale).
Copyright Text: This dataset was compiled by Lisa Eidson, Webmaster for Wilderness.net at the University of Montana's Wilderness Institute, to form individual wilderness boundaries obtained from the Fish and Wildlife Service (FWS), Bureau of Land Management (BLM), National Park Service (NPS), and the Forest Service (USFS). FS data has been obtained from the Automated Lands Project, or from regional or national forest GIS staff. BLM data is from a national dataset from field inventories. FWS and NPS data have been obtained from National Park or Refuge offices. For a history of updates, contacts from whom the data were obtained can be cross-referenced using the WID in the spreadsheet at http://www.wilderness.net/GIS/WildernessUpdates.xls.
Description: This dataset depicts the land ownership status, formal place name designations, administrative areas of responsibility for the State of Utah, primarily consistent with 1:24,000 or finer map accuracy goals. Users are strongly encouraged to familiarize themselves with the ‘Data Content’ section below as there are several key fields that unlock multiple possible layers from this single layer. The key fields that users should review and understand are named: OWNER, OWNERAGENCY, ADMIN, DESIG and the two LABEL fields as values from these fields can be used to select subsets for display or analysis (see example layers below). Revisions are posted weekly to AGRC’s SGID’s database, services, and file-based download products. Maintenance of this data layer is performed by a cooperative federal and state effort. The Utah School and Institutional Trust Lands Administration (SITLA) revises this data regularly to reflect changes in State Trust Lands, other State Land and Private Land as needed. The BLM contributes updates to this data to reflect changes in Federal Land as needed. Other information is edited and updated as needed but not on a regular schedule. No warranties or certification, express or implied, are provided for the statewide Land Ownership and related GIS mapping layer. This data product has been compiled as a best effort service strictly for general purpose informational use and any interpretations made are the responsibility of the User. Updates to this layer are expected later in 2017 and forward as AGRC, SITLA and partners adopt and implement the ESRI Parcel Fabric Data Model for the Public Land Survey System. This is expected to be done county by county. Data Content: Important descriptive attribute fields listed with valid values or, a short description of features with 'name' label attributes and examples. OWNER (The physical Owner of the parcel of land) * Federal (Owned by The United States of America) * Private (Private, County, City or Town Ownership) * State (Owned by the State of Utah) * Tribal (Native American Tribal Ownership) OWNER AGENCY (The physical Agency who is responsible for the parcel ownership, OWNER AGENCY may differ from ADMIN if the agency is NOT the administrator of the parcel) * BLM (US Bureau of Land Management) * BR (US Bureau of Reclamation) * DNR (State of Utah Department of Natural Resources) * DOD (US Department of Defense) * DOE (US Department of Energy) * NPS (US National Park Service) * OS (Other State Agency, State Facilities, and others state holdings) * OF (United States Other Federal Land may include any of the following: AEC, BOM, FAA, GSA, or others) * Private (Privately held properties, including City, County and Non-Profit) * SITLA (State of Utah School and Institutional Trust Lands Administration) * Tribal (Tribal Lands) * UDOT (State of Utah Department of Transportation) * USFS (US Forest Service) * USFWS (US Fish and Wildlife Service) ADMIN (Name of the Entity with Administrative Jurisdiction to the parcel) * BLM (US Bureau of Land Management) * BR (US Bureau of Reclamation) * DOD (US Department of Defense) * DOE (US Department of Energy) * NPS (National Park Service) * OS (State of Utah, Other holdings) * Private (Privately held properties) * SITLA (School and Institutional Trust Lands Administration) * SLandF (Utah DNR - Div. of Forestry, Fire and State Lands) * Tribal (Tribal lands) * UDWR (Utah DNR - Div. of Wildlife Resources) * UDOT (Utah Department of Transportation) * USFS (US Forest Service) * USFWS (US Fish and Wildlife Service) * USP (Utah DNR - State Parks) DESIG (the "type" of land use or designation – general land management designations) Describes the "Type" of Land Use or Designation. This field characterizes general land management designations for parcels of land and describes how, or for what use the land is to be managed (ex: Designated as Wilderness, National Park, State Park). This field can accommodate, if necessary, further withdrawals, leases, or permits designated by the ADMIN. E.g. If the USFS places a withdrawal on a parcel, i.e. for wilderness designation, the DESIG field can be used to account for this case. However, only a single designation can be addressed in the DESIG field; we cannot account for multiple withdrawals, leases, or permits on a parcel in this data standard. The data steward or editor must decide the most pertinent information to describe in the DESIG field. * Bankhead Jones (Federal lands (BLM and USFS) acquired under the Bankhead-Jones Farm Tenant Act) * Conservation Lands (Land that is being protected, through outright purchase or the purchase of development rights. Easements are held by private non-profit organizations, municipalities and fed or state agencies.) * Indian Reservation (Indian Reservations and/or Native American Tribal Lands) * Military (Military Reservations and Corps of Engineers) * N/A (No specified designation) * National Forest (US National Forest) * National Historic Site (US National Historic Site) * National Monument (US National Monument) * National Park (US National Park) * National Recreation Area (US National Recreation Area) * National Wildlife Refuge (US National Wildlife Refuge) * Other (Designation not specified in detail) * Parks and Recreation (Parks and Recreation Areas) * Primitive Area (US Primitive Area) * Public Water Reserve (US Public Water Reserve) * Reclamation Withdrawl (US Reclamation Withdrawl) * Repository (US Repository) * State Sovereign Land (Sovereign Land consists of the beds of Utah's navigable rivers and lakes) * State Trust Land (State of Utah School and Institutional Trust Lands Administration (SITLA) is an independent agency of state government.

Description: The quadrangle straddles urban and rural areas along the Interstate 80 corridor west of Salt Lake City. The map area is in the eastern Basin and Range Province and includes several mainly north-south-trending mountain ranges and intervening valleys and the southern part of Great Salt Lake. Bedrock geologic units from Precambrian to Miocene age are overlain by Tertiary and Quaternary surficial deposits. Geologic structure is related to the Uinta-Tooele structural zone, Sevier orogenic belt, and Basin and Range extension. Surficial deposits are largely related to late Pleistocene Lake Bonneville, Great Salt Lake, and alluvial depositional environments. This map shows the geology of the quadrangle at an intermediate scale (1:62,500). The accompanying map explanation includes an introductory text, geologic unit descriptions, figures, tables, photos, mapping sources, geologic units, correlation charts, geologic symbols, lithologic columns, and geologic cross sections.

Description: This GIS dataset was completed in 2017 by the Utah Geological Survey (UGS) and is reproduced from Thaden, R.E., Trites, A.F., Jr., and Finnell, T.L., 1964, Geology and ore deposits of the White Canyon area, San Juan and Garfield Counties, Utah: U.S. Geological Survey Bulletin 1125, 166 p., 4 pl., scale 1:48,000. This dataset represents geologic map features of the greater central Colorado River-White Canyon-Red Canyon area and includes parts of Glen Canyon National Recreation Area, Natural Bridges National Monument, and Bears Ears National Monument in southeastern Utah. The map is compiled for use at 1:48,000 scale. The map depicts geologic formations, faults, paleo-channels, structural contours, mines, and other information, and is accompanied by explanatory information including map-unit descriptions, geologic symbols, and a 166-page bulletin.The White Canyon area includes about 700 square miles in the west-central part of San Juan County and the eastern part of Garfield County, southeastern Utah, near the center of the Colorado Plateau physiographic province. Sedimentary formations ranging in age from Pennsylvanian to Jurassic crop out in the map area. The map area is on the west flank of the Monument upwarp, and strata have a regional dip of 2° to 3° westward. Low-amplitude flexures locally modify the regional dip of the strata. Vertical and steeply dipping normal faults are in the southwestern part of the area; grabens and horsts are bounded by normal faults that trend mostly N. 60°-80° W., and dip 65° to vertical, but some trend N. 50°-60° E. The most conspicuous joints in the area are nearly vertical and trend N. 65° W., N. 35° E., N. 65° E., and due north.Mineral deposits in the map area are copper-uranium and copper deposits in the Shinarump Conglomerate Member of the Chinle Formation. Most of the uranium and copper is localized in medium- to coarse-grained and conglomeratic sandstone interbedded with mudstone that fills channels cut into the Moenkopi Formation. Seventy-five channels were mapped—16 of them contain at least one uranium deposit having a grade of 0.10 percent or more U3O8. At least eight additional channels contain uraniferous material. Many different minerals associated with uranium are found elsewhere in the quadrangle. Descriptions of ore deposits and guides to locate ore bodies are reported in the original bulletin.This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some unit names, geologic line symbols, and unit descriptions to better match newer mapping in the area and the UGS 2017 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1964 and does not meet all modern cartographic, spatial control, or geologic standards. Not all features on the original map precisely match options in the 2017 UGS geologic map schema as noted below.Normal faultsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Original attributes are “Fault, showing dip – Dashed where approximately located; dotted where concealed; U, upthrown side; D, downthrown side.” These lines are now depicted as “Fault, normal, well located,” “Fault, normal, concealed,” or “Fault, normal, approximately located.”General faultsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Some line types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, unknown, well located,” “Fault, unknown, approximately located,” or “Fault, unknown, concealed.”Structure contoursLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Original attributes are “Structure contour – Drawn on top of the Wingate sandstone and Hoskinnini member - Dashed where approximately located.” These lines are now depicted as “Structure contour, datum 1,” “Structure contour, datum 1, projected above ground,”“Structure contour, datum 2,” or “Structure contour, datum 2, projected above ground.”Paleo Channel FillsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Original attributes are “Channel filled with sediments of the Shinarump member of the Chinle formation – Dashed where inferred.” These lines are now depicted as “Paleo-Channel fill, well located” or “Paleo-Channel fill, approximately located.”Units – Unit Symbols/Names/AgesThe following changes in formation and unit names were made to partially match modern usage in the area:Qt – Tufa is now Qst – Spring tufa, Ql – Landslides is now Qms – Mass movement landslides, Qld – Lacustrine deposits is now Ql – Lacustrine deposits, Qg – Gravel is now Qatg – Terrace gravel, Qtb – Talus breccia is now Qmt – Mass movement talus deposits, Qcl – Colluvium is now Qc – Colluvium, Qd – Dune sand is now Qed – Eolian dune sand, Jsr – San Raphael group, undifferentiated is now Jtcc – Temple Cap Formation (former Page Ss) and Carmel Formation, TRw – Wingate sandstone is now JTRw – Wingate Sandstone, TRcss – siltstone-sandstone unit of the Chinle Formation is now TRcc – Church Rock Member of Chinle Formation, TRcl – limy unit of the Chinle Formation is now TRcop – Owl Rock and Petrified Forest Members of Chinle Formation, TRcm – Moss Back member of the Chinle Formation is now TRcms – Moss Back Member of Chinle Formation, TRcms – mudstone-sandstone unit of the Chinle Formation is now TRcmn – Monitor Butte Member of Chinle Formation, Pcw – White Rim sandstone member of the Cutler formation is now Pwr – White Rim Sandstone, Pco – Organ Rock tongue of the Cutler formation is now Po – Organ Rock Formation, Pcc – Cedar Mesa sandstone member of the Cutler formation is now Pcm – Cedar Mesa Sandstone, PIPr – Rico formation is now PIPcl – lower Cutler beds (Halgaito Formation), and IPh – Hermosa formation is now IPht – Honaker Trail Formation.Ages were also slightly modified to match modern usage.

Description: This GIS dataset was completed in 2017 by the Utah Geological Survey (UGS) and is reproduced from Thaden, R.E., Trites, A.F., Jr., and Finnell, T.L., 1964, Geology and ore deposits of the White Canyon area, San Juan and Garfield Counties, Utah: U.S. Geological Survey Bulletin 1125, 166 p., 4 pl., scale 1:48,000. This dataset represents geologic map features of the greater central Colorado River-White Canyon-Red Canyon area and includes parts of Glen Canyon National Recreation Area, Natural Bridges National Monument, and Bears Ears National Monument in southeastern Utah. The map is compiled for use at 1:48,000 scale. The map depicts geologic formations, faults, paleo-channels, structural contours, mines, and other information, and is accompanied by explanatory information including map-unit descriptions, geologic symbols, and a 166-page bulletin.The White Canyon area includes about 700 square miles in the west-central part of San Juan County and the eastern part of Garfield County, southeastern Utah, near the center of the Colorado Plateau physiographic province. Sedimentary formations ranging in age from Pennsylvanian to Jurassic crop out in the map area. The map area is on the west flank of the Monument upwarp, and strata have a regional dip of 2° to 3° westward. Low-amplitude flexures locally modify the regional dip of the strata. Vertical and steeply dipping normal faults are in the southwestern part of the area; grabens and horsts are bounded by normal faults that trend mostly N. 60°-80° W., and dip 65° to vertical, but some trend N. 50°-60° E. The most conspicuous joints in the area are nearly vertical and trend N. 65° W., N. 35° E., N. 65° E., and due north.Mineral deposits in the map area are copper-uranium and copper deposits in the Shinarump Conglomerate Member of the Chinle Formation. Most of the uranium and copper is localized in medium- to coarse-grained and conglomeratic sandstone interbedded with mudstone that fills channels cut into the Moenkopi Formation. Seventy-five channels were mapped—16 of them contain at least one uranium deposit having a grade of 0.10 percent or more U3O8. At least eight additional channels contain uraniferous material. Many different minerals associated with uranium are found elsewhere in the quadrangle. Descriptions of ore deposits and guides to locate ore bodies are reported in the original bulletin.This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some unit names, geologic line symbols, and unit descriptions to better match newer mapping in the area and the UGS 2017 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1964 and does not meet all modern cartographic, spatial control, or geologic standards. Not all features on the original map precisely match options in the 2017 UGS geologic map schema as noted below.Normal faultsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Original attributes are “Fault, showing dip – Dashed where approximately located; dotted where concealed; U, upthrown side; D, downthrown side.” These lines are now depicted as “Fault, normal, well located,” “Fault, normal, concealed,” or “Fault, normal, approximately located.”General faultsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Some line types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, unknown, well located,” “Fault, unknown, approximately located,” or “Fault, unknown, concealed.”Structure contoursLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match. Original attributes are “Structure contour – Drawn on top of the Wingate sandstone and Hoskinnini member - Dashed where approximately located.” These lines are now depicted as “Structure contour, datum 1,” “Structure contour, datum 1, projected above ground,”“Structure contour, datum 2,” or “Structure contour, datum 2, projected above ground.”Paleo Channel FillsLine attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map.

Description: This digital dataset represents the Interim Geologic Map of the Northwestern Quarter of the Beaver 30' x 60' Quadrangle, Beaver and Piute Counties, Utah.It is a revised portion of the entire quadrangle map originally published in 2005 as UGS Open-File Report 454. The revisions reflect our current understanding of the newly discovered Black Mountains and Markagunt gravity slides, parts of perhaps the world’s largest terrestrial landslide complex, which we now know spans much of the Beaver 30' x 60' quadrangle. The map also incorporates new mapping of surficial deposits in the Escalante Desert, here simplified for reasons of map scale, done as part of the Utah FORGE (Frontier Observatory for Research in Geothermal Energy) project. We continue to work on revisions of the remainder of the quadrangle and surrounding areas.

Description: This dataset represents the geology of the Deep Creek Mountains Wilderness Study Area at 1:50,000 scale.This GIS dataset is reproduced from “Rodgers, D.W., 1989, Geologic map of the Deep Creek Mountains Wilderness Study Area, Tooele and Juab Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-2099, 1 plate, scale 1:50,000.” The map covers approximately six 7.5' quadrangles in west-central Utah. The GIS dataset was completed by Joshua Meibos, student at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, Martha L. Jensen, and Rosemary Fasselin, GIS Analysts with the Utah Geological Survey (UGS).The UGS appreciates the volunteered time and effort of the student Joshua Meibos who produced the GIS data for this project in 2016 under the guidance of Brigham Young University professor Eric Christiansen.Late Proterozoic and Paleozoic rocks of the Deep Creek Range form a thick sequence that accumulated in fluvial to shallow marine environments on a subsiding continental shelf. In the Late Cretaceous, possibly earlier, deep seated Late Proterozoic strata were regionally metamorphosed and a cleavage formed in mudstone, most likely accommodating east-directed translation of the entire stratigraphic sequence. Thrusting along the Birch Canyon fault and Rocky Springs thrust may have occurred at this time. The geometry and timing of these structures suggest they formed in the hinterland of the Sevier fold and thrust belt, coeval with east-directed thrusting in central Utah (Armstrong, 1968; Lawton, 1985). Between 73 Ma and 39 Ma, Late Proterozoic to Mississippian strata in the southern Deep Creek Range were folded into the Water Canyon anticline, which may also reflect east-west shortening in the hinterland of the Sevier fold and thrust belt. After emplacement of the 39 Ma Ibapah stock, possibly in the early Miocene, the Reilly Canyon normal fault extended to a depth of about 9 miles and accommodated differential uplift and east-west extension of the Deep Creek Range. Due to fault rotation, the entire range was tilted to the west during uplift. Finally, late Tertiary and Quaternary uplift along normal faults produced the modern Deep Creek Range. This fault geometry and timing is typical of the Basin and Range Province.This dataset was produced as part of a UGS multi-decade effort to provide statewide GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic issues such as attributing faults. We changed some geologic line symbols to better match the UGS 2020 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1989 and does not meet all modern cartographic, spatial control, or geologic standards.The GeoTiff file utilizes a basemap from the USGS US Topo Clifton, Goshute, Goshute Canyon, Ibapah, Ibapah Peak, Indian Farm Creek, Partoun, and Trout Creek 7.5' Quadrangles (2017).Not all features on the original map precisely match options in the 2020 UGS geologic map schema as noted below. Line attributes and symbology were selected from current (2020) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match.FaultThese lines are now depicted as "Fault, unknown, well located," "Fault, unknown, approximately located," "Fault, unknown, approximately located, queried," "Fault, unknown, concealed," or "Fault, unknown, concealed, queried."

Description: This dataset represents the geology of the Deep Creek Mountains Wilderness Study Area at 1:50,000 scale.This GIS dataset is reproduced from “Rodgers, D.W., 1989, Geologic map of the Deep Creek Mountains Wilderness Study Area, Tooele and Juab Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-2099, 1 plate, scale 1:50,000.” The map covers approximately six 7.5' quadrangles in west-central Utah. The GIS dataset was completed by Joshua Meibos, student at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, Martha L. Jensen, and Rosemary Fasselin, GIS Analysts with the Utah Geological Survey (UGS).The UGS appreciates the volunteered time and effort of the student Joshua Meibos who produced the GIS data for this project in 2016 under the guidance of Brigham Young University professor Eric Christiansen.Late Proterozoic and Paleozoic rocks of the Deep Creek Range form a thick sequence that accumulated in fluvial to shallow marine environments on a subsiding continental shelf. In the Late Cretaceous, possibly earlier, deep seated Late Proterozoic strata were regionally metamorphosed and a cleavage formed in mudstone, most likely accommodating east-directed translation of the entire stratigraphic sequence. Thrusting along the Birch Canyon fault and Rocky Springs thrust may have occurred at this time. The geometry and timing of these structures suggest they formed in the hinterland of the Sevier fold and thrust belt, coeval with east-directed thrusting in central Utah (Armstrong, 1968; Lawton, 1985). Between 73 Ma and 39 Ma, Late Proterozoic to Mississippian strata in the southern Deep Creek Range were folded into the Water Canyon anticline, which may also reflect east-west shortening in the hinterland of the Sevier fold and thrust belt. After emplacement of the 39 Ma Ibapah stock, possibly in the early Miocene, the Reilly Canyon normal fault extended to a depth of about 9 miles and accommodated differential uplift and east-west extension of the Deep Creek Range. Due to fault rotation, the entire range was tilted to the west during uplift. Finally, late Tertiary and Quaternary uplift along normal faults produced the modern Deep Creek Range. This fault geometry and timing is typical of the Basin and Range Province.This dataset was produced as part of a UGS multi-decade effort to provide statewide GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users.

Description: This digital dataset represents the geology of the Grouse Creek and east part of the Jackpot 30' x 60' quadrangles at 1:62,500 scale. The map area lies in the northwest corner of Utah and covers the hinterland of the Sevier fold-thrust belt, part of the Albion-Raft River-Grouse Creek metamorphic core complex, and eastern Basin and Range Province, thus leading to very complicated structural relationships. The area includes the oldest exposed rocks in Utah, the Green Creek Complex (~2.6 Ga, Archean). Overlying Neoproterozoic metamorphic rocks include schist and quartzite units, and parts of the Neoproterozoic and Paleozoic sections have been metamorphosed and severely attenuated. Several marine Permo-Triassic units were also structurally deformed through compression and extension. Eocene-Oligocene volcanism occurred during the onset of another phase of extension. A thick sequence of Tertiary strata (Salt Lake Formation) and coeval volcanic rocks fill several basins developed during the Miocene extensional regime; new age data help constrain the timing. Deposits of Lake Bonneville and other Quaternary depositional environments blanket large parts of the quadrangles. Geologic map preparation and interpretations were substantially aided by the acquisition of geophysical (gravity and aeromagnetic) data. This project is a cooperative effort between the U.S. Geological Survey and the Utah Geological Survey.

Description: This GIS dataset is reproduced from Dubiel, R.F., Bromfield, C.S., Larson, M.J., Patterson, C.G., and Peterson, Fred, 1985, Geologic map of the Dirty Devil, French Spring-Happy Canyon, and Horseshoe Canyon Wilderness Study Areas, Wayne and Garfield Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-1754-B, 1 plate, scale 1:50,000. The map is compiled for use at 1:50,000 scale. The map depicts geologic formations, faults, bedding attitudes, folds, and other information, and is accompanied by explanatory information including correlation of map units, description of map units, structure discussion, references, and map symbols.This map covers a large tract of the southern San Rafael Desert area of south-central Utah. It extends from approximately Utah highways 24 and 95 east to near the Green and Colorado Rivers, and from the Wayne-Emery county line south into northern Garfield County. It includes a large part of the northern arm of Glen Canyon National Recreation Area in the northern Orange Cliffs area. It includes most of the Dirty Devil River and its tributaries. Prominent features include the Dirty Devil River and its canyons, Robbers Roost Canyon and Flats, Horseshoe Canyon, French Springs, Happy Canyon, the northern Orange Cliffs, and the Burr Desert. Exposed strata range from the upper part of the Upper Triassic Chinle Formation to the Middle Jurassic Entrada Sandstone. Overall, strata dip westward on the lower west flank of the Monument uplift. Locally, they are gently warped into smaller folds and cut by a few small-displacement normal faults. Much of the landscape is stark redrock desert with extensive exposed bedrock. Tributaries of the Dirty Devil River are deeply incised into the terrain. Large pediments mantled with mostly igneous rocks extend from the Henry Mountains into the western part of the map area west of the river. Most roads and trails are on broad benches with old calcic “hardpan” soils (caliche). Eolian sand and silt mantle most of these older surfaces. This dataset was produced as part of a Utah Geological Survey (UGS) multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match newer mapping in the area and the UGS 2019 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was released in 1985 and does not meet all modern cartographic, spatial control, or geologic standards.This map was compiled by the authors from published and unpublished sources. Some features were field verified, but it still should be considered a reconnaissance-type map. Comparison with current georectified orthophotographic imagery showed that spatial accuracy ranges from fairly accurate (generally within 10 to 20 meters) to very poor (some lines misplaced by more than 100 meters). The UGS did not attempt to improve the spatial fit of any features.Not all features on the original map precisely match options in the 2019 UGS geologic map schema as noted below. Line attributes and symbols were selected from current (2019) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map but are not an exact match.Normal FaultsThese lines are now depicted as normal faults and unknown faults. Downthrown side is shown with bar and ball symbol.Anticlines and SynclinesThese lines are now depicted as approximately located or concealed where they are covered with Quaternary deposits.Units – Unit Symbols/NamesWhile we did not attempt to improve or change geologic map contacts or features, we did change some map unit labels to formation and member names preferred by most current workers in the area as explained in the GIS map metadata. On this map we replaced Page Sandstone with Temple Cap Formation following Doelling, H.H., Sprinkel, D.A., Kowallis, B.J., and Kuehne, P.A., 2013, Temple Cap and Carmel Formations in the Henry Mountains Basin, Wayne and Garfield Counties, Utah, In Morris, T.H., and Ressetar, R., editors, The San Rafael Swell and Henry Mountains Basin—geologic centerpiece of Utah: Utah Geological Association Publication 42, p. 279–318, appendices.

Description: This GIS dataset is a reproduction of plate 1 (geologic map) of “O’Sullivan, Robert B., 1965,Geology of the Cedar Mesa–Boundary Butte Area, San Juan County, Utah: U.S. Geological Survey Bulletin 1186, 128 p., 1 plate, scale 1:62,500.” The GIS dataset was prepared by Lori Steadman, GIS Analyst with the Utah Geological Survey (UGS). Grant Willis, UGS Geologist, managed and reviewed the project and updated the stratigraphic nomenclature.The map covers the scenic San Juan River area of southeastern Utah from east of the town of Bluff to west of the town of Mexican Hat. The Monument Upwarp covers the western half of the map area; the Blanding Basin covers the eastern half. They are separated by the spectacular east-facing Comb Ridge monocline that forms a huge north-south topographic barrier between them. Both the upwarp and the basin are warped into smaller anticlines and synclines. The largest and most scenic is the Raplee anticline that is cut by a deep river canyon that is very popular for river float trips. The San Juan River cuts an ever-deepening canyon as it flows westward across the area. Goosenecks State Park is a popular viewpoint overlooking deeply entrenched meanders of the river’s lower canyon. Grand Gulch Wilderness Study Area is in the northwestern part of the quadrangle and Monument Valley, the setting of many old western movies, is in the southwestern part. More than half the map area is on the Navajo Indian Reservation. Exposed strata ranges from the Pennsylvanian Paradox Formation exposed in the deepest canyons to the Upper Jurassic Brushy Basin Member of the Morrison Formation preserved as remnants on mesas in the northeastern part. Intrusions of mafic igneous rock, called minette, intruded as dikes, sills, plugs, and diatremes and weather out in relief as dark ribs and pinnacles that strikingly contrast with the red, tan, and gray sedimentary rock. The map area covers part of the Paradox Basin oil fields and hundreds of oil and gas exploration and development holes have been drilled. The map was created during the “uranium boom” though the area did not prove productive even though it has extensive outcrops of the primary uranium-bearing formations. The map area is also famous for many well-preserved Ancestral Puebloan ruins. This dataset was produced as part of a UGS multi-decade effort to provide statewide GIS data to the public, federal, state and local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic issues such as a few slight modifications to fault and attitude placement and line attribute corrections. We changed some geologic line and point symbol attributes to better match the UGS 2019 data model. We also changed the names and labels of some formations and members to match 2019 nomenclature usage. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1965 and does not meet all modern cartographic, spatial control, or geologic standards. In particular, spatial placement of some contacts is poor compared to current base maps, and some contacts and correlations of the members of the Morrison Formation do not match those of current publications on the area.This map was compiled by the authors from published and unpublished sources. Some features were field verified, but it still should be considered a reconnaissance-type map. Comparison with current georectified orthophotographic imagery showed that spatial accuracy ranges from fairly accurate (generally within 10 to 20 meters) to very poor (some lines misplaced by more than 100 meters). The UGS did not attempt to improve the spatial fit of any features.Line attributes and symbols were selected from current (2019) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted on the original map, but are not an exact match.ContactsOriginal attributes are “Contact – dashed where approximately located”. These lines are now depicted as “Contact, well located” or“Contact, dashed where approximately located”.Unit Shown as Single LineThe map unit “limestone A of Honaker Trail or Halgaito Formation (PIPhta)” is shown as a colored contact in steep areas where it is shown as a single line on the original map.Scratch or Gradational ContactIn an area on the northern part of the original map, the contact between two units is shown as just a color change without a line. It is not explained in the map legend but the text explains that it is a difficult-to-map gradational zone. We have shown it as a scratch contact.FaultsOriginal attributes are “Fault – dashed where approximately located; dotted where concealed, bar and ball on downthrown side”. We use a normal fault designation for these faults even though we have not confirmed in the field that all of these faults are normal.Units – Descriptions/Names/AgesAs noted above, some units names have been changed to 2019 usage. Descriptions have not been changed.Drill HolesDrill holes are shown the same as on the original map and locations and names have not been verified or modified based on newer Division of Oil Gas and Mining records. Table 1 was copied directly from the original text; the text gives it a date of 1962 though the map publication date is 1965. Each drill hole is attributed with an identification number that links it to Table 1 and is shown on the map. The original map is labeled with the drill hole depth, which is listed in Table 1.

Intrusions of mafic igneous rock, called minette, intruded as dikes, sills, plugs, and diatremes and weather out in relief as dark ribs and pinnacles that strikingly contrast with the red, tan, and gray sedimentary rock. The map area covers part of the Paradox Basin oil fields and hundreds of oil and gas exploration and development holes have been drilled. The map was created during the “uranium boom” though the area did not prove productive even though it has extensive outcrops of the primary uranium-bearing formations. The map area is also famous for many well-preserved Ancestral Puebloan ruins. This dataset was produced as part of a UGS multi-decade effort to provide statewide GIS data to the public, federal, state and local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic issues such as a few slight modifications to fault and attitude placement and line attribute corrections. We changed some geologic line and point symbol attributes to better match the UGS 2019 data model. We also changed the names and labels of some formations and members to match 2019 nomenclature usage. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1965 and does not meet all modern cartographic, spatial control, or geologic standards. In particular, spatial placement of some contacts is poor compared to current base maps, and some contacts and correlations of the members of the Morrison Formation do not match those of current publications on the area.This map was compiled by the authors from published and unpublished sources. Some features were field verified, but it still should be considered a reconnaissance-type map. Comparison with current georectified orthophotographic imagery showed that spatial accuracy ranges from fairly accurate (generally within 10 to 20 meters) to very poor (some lines misplaced by more than 100 meters). The UGS did not attempt to improve the spatial fit of any features.Line attributes and symbols were selected from current (2019) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted on the original map, but are not an exact match.ContactsOriginal attributes are “Contact – dashed where approximately located”. These lines are now depicted as “Contact, well located” or“Contact, dashed where approximately located”.Unit Shown as Single LineThe map unit “limestone A of Honaker Trail or Halgaito Formation (PIPhta)” is shown as a colored contact in steep areas where it is shown as a single line on the original map.Scratch or Gradational ContactIn an area on the northern part of the original map, the contact between two units is shown as just a color change without a line. It is not explained in the map legend but the text explains that it is a difficult-to-map gradational zone. We have shown it as a scratch contact.FaultsOriginal attributes are “Fault – dashed where approximately located; dotted where concealed, bar and ball on downthrown side”. We use a normal fault designation for these faults even though we have not confirmed in the field that all of these faults are normal.Units – Descriptions/Names/AgesAs noted above, some units names have been changed to 2019 usage. Descriptions have not been changed.Drill HolesDrill holes are shown the same as on the original map and locations and names have not been verified or modified based on newer Division of Oil Gas and Mining records. Table 1 was copied directly from the original text; the text gives it a date of 1962 though the map publication date is 1965. Each drill hole is attributed with an identification number that links it to Table 1 and is shown on the map. The original map is labeled with the drill hole depth, which is listed in Table 1.

Description: This GIS dataset is a reproduction of plate 1 (geologic map) of “O’Sullivan, Robert B., 1965,Geology of the Cedar Mesa–Boundary Butte Area, San Juan County, Utah: U.S. Geological Survey Bulletin 1186, 128 p., 1 plate, scale 1:62,500.” The GIS dataset was prepared by Lori Steadman, GIS Analyst with the Utah Geological Survey (UGS). Grant Willis, UGS Geologist, managed and reviewed the project and updated the stratigraphic nomenclature.The map covers the scenic San Juan River area of southeastern Utah from east of the town of Bluff to west of the town of Mexican Hat. The Monument Upwarp covers the western half of the map area; the Blanding Basin covers the eastern half. They are separated by the spectacular east-facing Comb Ridge monocline that forms a huge north-south topographic barrier between them. Both the upwarp and the basin are warped into smaller anticlines and synclines. The largest and most scenic is the Raplee anticline that is cut by a deep river canyon that is very popular for river float trips. The San Juan River cuts an ever-deepening canyon as it flows westward across the area. Goosenecks State Park is a popular viewpoint overlooking deeply entrenched meanders of the river’s lower canyon. Grand Gulch Wilderness Study Area is in the northwestern part of the quadrangle and Monument Valley, the setting of many old western movies, is in the southwestern part.

Description: This GIS dataset is reproduced from Patterson, C.G., Bromfield, C.S., Dubiel, R.F., Faulds, J.E., Larson, M.J., Milde, P.G., and Peterson, F., 1985, Geologic map of the Mt. Ellen-Blue Hills Wilderness Study Area and Bull Mountain study area, Garfield and Wayne Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-1756-B, 1 plate, scale 1:50,000. The map is compiled for use at 1:50,000 scale. The map depicts geologic formations, faults, bedding attitudes, folds, and other information, and is accompanied by explanatory information including correlation of map units, description of map units, structure discussion, references, and map symbols. This map covers the northern Henry Mountains and parts of flanking desert basins to the west, north, and east. It covers a large block in the western part of the Hanksville 30' x 60' quadrangle, and a small block in the eastern part of the Loa 30' x 60' quadrangle. It covers a large area just east of Capitol Reef National Park and includes Mt. Ellen, Table Mountain, Bull Mountain, South Caineville Mesa, Upper Blue Hills, Blue Valley, Blue Valley Benches, part of the Caineville Reef, the southern part of Red Desert, and a section of the Fremont River. State highway 24 passes through the northern part of the map area and highway 95 passes through the eastern part. Caineville Reef is an east-verging Laramide monoclinal fold. East of the reef, Upper Cretaceous strata are preserved in the synclinal Henry basin. Jurassic strata are exposed in the eastern and western parts of the map area. The Henry Mountains are the eroded remnants of Oligocene igneous laccoliths that intruded and steeply bowed up sedimentary rocks. Much of the landscape is stark redrock and blue-gray desert with exposed bedrock. Tributaries of the Fremont River are deeply incised into the terrain. Large pediments mantled with mostly igneous rocks extend from the Henry Mountains across much of the map area. Eolian sand and silt mantle some areas. This dataset was produced as part of a Utah Geological Survey (UGS) multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match newer mapping in the area and the UGS 2019 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was released in 1985 and does not meet all modern cartographic, spatial control, or geologic standards.This map was compiled by the authors from published and unpublished sources. Some features were field verified, but it still should be considered a reconnaissance-type map. Comparison with current georectified orthophotographic imagery showed that spatial accuracy ranges from fairly accurate (generally within 10 to 20 meters) to very poor (some lines misplaced by more than 100 meters). The UGS did not attempt to improve the spatial fit of any features.Not all features on the original map precisely match options in the 2019 UGS geologic map schema as noted below. Line attributes and symbols were selected from current (2019) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match.ContactsA few contacts were slightly modified to close polygons, and a few superfluous contacts between polygons of the same unit were removed. Near Table Mountain a large polygon on the original map is labeled Qcl (revised to Qc) in one location and Qg (revised to Qag) in another; we either had to add a contact or change one label. We chose to change the Qag label to Qc as it seems more consistent with nearby mapping. Normal FaultsThese lines are now depicted as normal faults and unknown faults. Downthrown side is shown with bar and ball symbol.Anticlines and SynclinesThese lines are now depicted as approximately located or concealed where they are covered with Quaternary deposits.Units – Unit Symbols/NamesWhile we did not attempt to improve or change geologic map contacts or features, we did change some map unit labels to formation and member names preferred by most current workers in the area as explained in the GIS map metadata. New or modified terms include: Tarantula Mesa Sandstone (Mesaverde Formation on original map), Masuk Formation (Masuk Member of Mancos Shale on original map), Muley Canyon Sandstone (Emery Sandstone Member of Mancos Shale on original map), Naturita Formation (replaces Dakota Formation throughout Utah), Morrison Formation, Salt Wash and Tidwell Members (Tidwell Member not noted on original map); we also noted that the Navajo Sandstone map unit includes the Temple Cap Formation. The Temple Cap replaces the older term Page Sandstone in this area following Doelling, H.H., Sprinkel, D.A., Kowallis, B.J., and Kuehne, P.A., 2013, Temple Cap and Carmel Formations in the Henry Mountains Basin, Wayne and Garfield Counties, Utah, In Morris, T.H., and Ressetar, R., editors, The San Rafael Swell and Henry Mountains Basin—geologic centerpiece of Utah: Utah Geological Association Publication 42, p. 279–318, appendices.

Description: This GIS dataset is reproduced from Patterson, C.G., Bromfield, C.S., Dubiel, R.F., Faulds, J.E., Larson, M.J., Milde, P.G., and Peterson, F., 1985, Geologic map of the Mt. Ellen-Blue Hills Wilderness Study Area and Bull Mountain study area, Garfield and Wayne Counties, Utah: U.S. Geological Survey Miscellaneous Field Studies Map MF-1756-B, 1 plate, scale 1:50,000. The map is compiled for use at 1:50,000 scale. The map depicts geologic formations, faults, bedding attitudes, folds, and other information, and is accompanied by explanatory information including correlation of map units, description of map units, structure discussion, references, and map symbols. This map covers the northern Henry Mountains and parts of flanking desert basins to the west, north, and east. It covers a large block in the western part of the Hanksville 30' x 60' quadrangle, and a small block in the eastern part of the Loa 30' x 60' quadrangle. It covers a large area just east of Capitol Reef National Park and includes Mt. Ellen, Table Mountain, Bull Mountain, South Caineville Mesa, Upper Blue Hills, Blue Valley, Blue Valley Benches, part of the Caineville Reef, the southern part of Red Desert, and a section of the Fremont River. State highway 24 passes through the northern part of the map area and highway 95 passes through the eastern part. Caineville Reef is an east-verging Laramide monoclinal fold. East of the reef, Upper Cretaceous strata are preserved in the synclinal Henry basin. Jurassic strata are exposed in the eastern and western parts of the map area. The Henry Mountains are the eroded remnants of Oligocene igneous laccoliths that intruded and steeply bowed up sedimentary rocks. Much of the landscape is stark redrock and blue-gray desert with exposed bedrock. Tributaries of the Fremont River are deeply incised into the terrain. Large pediments mantled with mostly igneous rocks extend from the Henry Mountains across much of the map area. Eolian sand and silt mantle some areas. This dataset was produced as part of a Utah Geological Survey (UGS) multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users.

Description: This GIS dataset is reproduced from Crittenden, M.D., Jr., 1988, Bedrock Geologic Map of the Promontory Mountains, Box Elder County, Utah: U.S. Geological Survey Open-File Report 88-646, 1 plate, scale 1:100,000. The map is compiled for use at 1:100,000 scale. The map depicts geologic formations, faults, bedding attitudes, folds, and other information, and is accompanied by explanatory information including correlation of map units, description of map units, structure discussion, references, symbols, and a generalized cross section.The Promontory Mountains are in the eastern Basin and Range physiographic province of north-central Utah, dominated by north-south-trending mountain ranges and broad valleys. The Promontory Mountains exhibit about 8 kilometers thickness of the upper plate of the Willard thrust, in which three major structural units are grouped by their age and internal structure: (1) a lower unit containing Neoproterozoic and Cambrian strata, (2) a middle unit of Ordovician to Upper Mississippian strata, and (3) and an upper unit of Upper Mississippian to Lower Permian strata. The structure reflects the Sevier fold-thrust belt and subsequent extensional tectonics.This dataset was produced as part of a Utah Geological Survey (UGS) multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match newer mapping in the area and the UGS 2017 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was released in 1988 and does not meet all modern cartographic, spatial control, or geologic standards. Not all features on the original map precisely match options in the 2017 UGS geologic map schema as noted below. Line attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted by the original map, but are not an exact match.Marker bedsThese lines are now depicted as “Bed, marker A,” "Bed, marker B," and "Bed, marker C."High-Angle faultsThese lines are now depicted as normal faults or unknown faults.Low-Angle faultsThese lines are now depicted as unknown faults, detachment faults, or thrust faults.BeddingThese symbols are now depicted as “Bedding, inclined,” “Bedding, overturned,” and “Bedding, vertical.”Units – Unit Symbols/NamesThe following changes in formation and unit names were made. We added unit Csn – St. Charles Dolomite and Nounan Dolomite, undivided. We added queries to selected units where original map labeling was poor. We used the unit label Zmc? for the Maple Canyon Formation (?). We queried the Jefferson Formation (unit Dj?) herein, as this nomenclature is likely incorrect for this area; further work is needed.

Description: This GIS dataset is reproduced from Crittenden, M.D., Jr., 1988, Bedrock Geologic Map of the Promontory Mountains, Box Elder County, Utah: U.S. Geological Survey Open-File Report 88-646, 1 plate, scale 1:100,000. The map is compiled for use at 1:100,000 scale. The map depicts geologic formations, faults, bedding attitudes, folds, and other information, and is accompanied by explanatory information including correlation of map units, description of map units, structure discussion, references, symbols, and a generalized cross section.The Promontory Mountains are in the eastern Basin and Range physiographic province of north-central Utah, dominated by north-south-trending mountain ranges and broad valleys. The Promontory Mountains exhibit about 8 kilometers thickness of the upper plate of the Willard thrust, in which three major structural units are grouped by their age and internal structure: (1) a lower unit containing Neoproterozoic and Cambrian strata, (2) a middle unit of Ordovician to Upper Mississippian strata, and (3) and an upper unit of Upper Mississippian to Lower Permian strata. The structure reflects the Sevier fold-thrust belt and subsequent extensional tectonics.This dataset was produced as part of a Utah Geological Survey (UGS) multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match newer mapping in the area and the UGS 2017 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was released in 1988 and does not meet all modern cartographic, spatial control, or geologic standards. Not all features on the original map precisely match options in the 2017 UGS geologic map schema as noted below. Line attributes and symbology were selected from current (2017) UGS schema and do not necessarily match the intent of the original map.

Description: This digital dataset represents the geology of the Panguitch 30' x 60' quadrangle at 1:62,500 scale. The quadrangle spans the southernmost High Plateaus in southwest Utah, a structural and stratigraphic transition zone between the highly extended Basin and Range Province on the west and the colorful, mostly flat-lying strata of the Colorado Plateau to the east. The structural grain of the map area is dominated by north- to northeast-trending normal faults that bound relatively unfaulted blocks represented by the Markagunt and Paunsaugunt-Sevier Plateaus. That grain is imprinted on the leading edge of the Sevier orogenic belt, whose thrust faults and folds are dramatically displayed in the Red Hills and in Cedar Canyon at the west edge of the map area, and whose subtle effects are documented eastward to the Paunsaugunt fault zone.The map area also includes the southern margin of the Marysvale volcanic field. Gravitational spreading of the southern sector of the volcanic field created unusual, east-trending, south-vergent thrust faults and folds of the Rubys Inn thrust fault zone, which is much younger than and trends nearly at a right angle to Sevier-age structures. Our mapping suggests that the Rubys Inn thrust fault continues westward into the Markagunt Plateau as a blind thrust fault roughly coincident with the southern margin of the Markagunt gravity slide. The Markagunt gravity slide, which apparently covers at least 1600 mi2(4160 km2) of the central and northern Markagunt Plateau and adjacent area, resulted from catastrophic collapse of the southwestern sector of the Marysvale volcanic field in the early Miocene, 21 to 22 million years ago. It is thus considerably larger than the famous Heart Mountain detachment of northwestern Wyoming, long known as the largest subaerial gravity slide in the world. We remain uncertain of what caused the collapse, but suggest that it may be related to pre-caldera inflation of the 20-18 Ma Mount Belknap caldera.The oldest rocks exposed in the map area, at Parowan Gap, belong to the Lower Jurassic Navajo Sandstone. Middle Jurassic strata are also exposed there, as well as in Cedar Canyon and south of Tropic. But it is Upper Cretaceous, Paleocene, and Eocene strata for which the quadrangle is most noteworthy. Our mapping documents correlation of Upper Cretaceous strata at the west edge of the Markagunt Plateau with better exposed and more thoroughly studied strata of the Kaiparowits basin east of the map area. Our mapping also constrains the evolution and demise of the Claron depositional basin, whose colorful strata are famously known at Cedar Breaks National Monument and Bryce Canyon National Park. For those interested in volcanic rocks, we report new late Eocene ages for the inception of volcanism in this part of southwest Utah, we map the distribution of regional ash-flow tuffs that erupted from Oligocene and Miocene calderas near the Utah-Nevada border (documenting paleotopography of the region and constraining the inception of basin-range faulting), and we map 38 relatively young basaltic lava flows and cinder cones, the most recent phase in the volcanic legacy of the southernmost High Plateaus. Because the map area contains such a wide range of young and old lava flows and ash-flow tuffs, it is adorned with inverted valleys representing each stage in the evolution of these enigmatic features. Several of these lava flows cross and are offset by faults associated with Basin and Range extension and so serve as markers for long-term slip rates on major normal faults in the area.This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats.

Gravitational spreading of the southern sector of the volcanic field created unusual, east-trending, south-vergent thrust faults and folds of the Rubys Inn thrust fault zone, which is much younger than and trends nearly at a right angle to Sevier-age structures. Our mapping suggests that the Rubys Inn thrust fault continues westward into the Markagunt Plateau as a blind thrust fault roughly coincident with the southern margin of the Markagunt gravity slide. The Markagunt gravity slide, which apparently covers at least 1600 mi2(4160 km2) of the central and northern Markagunt Plateau and adjacent area, resulted from catastrophic collapse of the southwestern sector of the Marysvale volcanic field in the early Miocene, 21 to 22 million years ago. It is thus considerably larger than the famous Heart Mountain detachment of northwestern Wyoming, long known as the largest subaerial gravity slide in the world. We remain uncertain of what caused the collapse, but suggest that it may be related to pre-caldera inflation of the 20-18 Ma Mount Belknap caldera.The oldest rocks exposed in the map area, at Parowan Gap, belong to the Lower Jurassic Navajo Sandstone. Middle Jurassic strata are also exposed there, as well as in Cedar Canyon and south of Tropic. But it is Upper Cretaceous, Paleocene, and Eocene strata for which the quadrangle is most noteworthy. Our mapping documents correlation of Upper Cretaceous strata at the west edge of the Markagunt Plateau with better exposed and more thoroughly studied strata of the Kaiparowits basin east of the map area. Our mapping also constrains the evolution and demise of the Claron depositional basin, whose colorful strata are famously known at Cedar Breaks National Monument and Bryce Canyon National Park. For those interested in volcanic rocks, we report new late Eocene ages for the inception of volcanism in this part of southwest Utah, we map the distribution of regional ash-flow tuffs that erupted from Oligocene and Miocene calderas near the Utah-Nevada border (documenting paleotopography of the region and constraining the inception of basin-range faulting), and we map 38 relatively young basaltic lava flows and cinder cones, the most recent phase in the volcanic legacy of the southernmost High Plateaus. Because the map area contains such a wide range of young and old lava flows and ash-flow tuffs, it is adorned with inverted valleys representing each stage in the evolution of these enigmatic features. Several of these lava flows cross and are offset by faults associated with Basin and Range extension and so serve as markers for long-term slip rates on major normal faults in the area.This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats.

Description: This data layer consists of National Wilderness Preservation System areas in the United States, Puerto Rico, and the U.S. Virgin Islands. The map layer was created by combining the best available data from the federal agency responsible for administration of a given wilderness area. Where larger scale data could not be obtained the National Atlas layer "National Wilderness Preservation System" was used as the data source. In its present form source data varies from a scale of 1:10000 to 1:2,000,000 (see lineage for details on source scale).
Copyright Text: This dataset was compiled by Lisa Eidson, Webmaster for Wilderness.net at the University of Montana's Wilderness Institute, to form individual wilderness boundaries obtained from the Fish and Wildlife Service (FWS), Bureau of Land Management (BLM), National Park Service (NPS), and the Forest Service (USFS). FS data has been obtained from the Automated Lands Project, or from regional or national forest GIS staff. BLM data is from a national dataset from field inventories. FWS and NPS data have been obtained from National Park or Refuge offices. For a history of updates, contacts from whom the data were obtained can be cross-referenced using the WID in the spreadsheet at http://www.wilderness.net/GIS/WildernessUpdates.xls.
Description: UGS completed a geologic map of the Rush Valley 30' x 60' quadrangle at 1:62,500 scale. The quadrangle lies on the fringe of the Salt Lake City metropolitan area with land use varied between public, military, Indian reservation, and private. The mapping is needed for proper management of land, water, and other economic resources. The map area lies within the eastern Basin and Range Province. Ranges are composed of unexposed basement rocks overlain by exposed Neoproterozoic through Triassic rocks about 10.4 miles (16.8 km) thick, and numerous Tertiary sedimentary and volcanic units (~47 to 20 Ma). The intervening valleys include bedrock covered with Miocene-Pliocene? rocks (~11 to 4 Ma) and Tertiary-Quaternary surficial deposits. The map area is on the south flank of the Uinta-Tooele structural zone. The quadrangle lies in the Charleston-Nebo (Provo) salient of the Sevier fold-thrust belt with some thrust faults exposed, but the overall geometry obscured by extensive valley fill and later faulting. Following Sevier deformation, calk-alkaline volcanism occurred from several Paleogene volcanic centers (42 to 25 Ma). Extensional tectonism created the distinctive basin and range topography from about 20 Ma to the present. Early extensional basin fill includes Miocene sedimentary and volcanic rocks followed by Pliocene-Holocene surficial deposits primarily from lacustrine and alluvial depositional environments. Valley areas were covered by late Pleistocene Lake Bonneville, and deposits are associated with three levels of regional shorelines. Normal faults cut the ranges and are known to bound some valley margins where not concealed. Although deep drill hole data are relatively sparse, gravity data were used to help constrain basin geometries.

Description: U.S. USGS 1:24,000 Topographic Quadrangle Series Indexes represents the geographic extent of USGS 1:24,000 topographic maps (7.5- by 7.5-minute quadrangles) for the coterminous U.S. forty-eight states and District of Columbia.
Description: This dataset represents the geology of the Escalante 30'x60'quadrangle at 1:100,000 scale. This open-file release makes GIS data available to the public during the review and production period necessary for a formal UGS publication. The map may be incomplete, and inconsistencies, errors, and omissions have not been resolved. While the document is in the review process, it may not conform to UGS standards; therefore, it may be premature for an individual or group to take actions based on its contents. This 2018 provisional open-file geologic map is a partially revised version of a 1999 open-file report (Doelling, H.H., and Willis, G.C., 1999, Interim geologic map of the Escalante and parts of the Loa and Hite Crossing 30' x 60' quadrangles, Garfield and Kane Counties, Utah, Utah Geological Survey Open-File Report 368). The 1999 map was partly compiled from several older geologic maps of various scales and had extensive new mapping and modifications by the authors to fill gaps and resolve inconsistencies. The map is being re-released to correct and improve a few selected geologic features, and to release an interim GIS database. However, most map features are not modified from the original and many aspects of the map do not meet modern standards of precision or accuracy. Most significant revisions were made along the western border to better match the recently published geologic map of the Panguitch 30' x 60' quadrangle (Biek and others, 2015b, Geologic map of the Panguitch 30' x 60' quadrangle, Garfield, Iron, and Kane Counties, Utah, Utah Geological Survey Map 270DM) and along the western part of the northern border to better match an interim geologic map of part of the Loa 30' x 60' quadrangle (Biek and others, 2015a, Interim geologic map of the Western Loa 30' x 60' quadrangle, Garfield, Piute, and Wayne Counties, Utah, Utah Geological Survey Open-File Report 648). A few unit names were updated and revised ages and selected other information were added to a few geologic unit descriptions. Spatial placement of most other geologic features is based on methods used in the 1980–90s and does not match modern standards. The Escalante 30' x 60' quadrangle straddles the high plateaus and western Colorado Plateau of south-central Utah and extends from Johns Valley near Bryce Canyon National Park across the Escalante Mountains, Kaiparowits Plateau, Escalante River basin, Circle Cliffs, and Water Pocket Fold, and includes part of Capitol Reef National Park. Exposed rocks range from Permian White Rim Sandstone and Kaibab Formation to Tertiary volcanic tuffs derived from the Marysvale volcanic field. Johns Valley near the western border is a deep graben. The rest of the quadrangle is dominated by broad north- to north-northwest-trending asymmetric folds with generally steep eastern limbs; the largest and most famous is the Waterpocket Fold that forms the heart of Capitol Reef National Park. Surficial alluvial, mass movement, colluvial and eolian deposits are abundant, especially in the higher elevations. This mapping is intended for use at 1:100,000 or smaller scale. This map was produced using various topographic and photographic base maps for spatial (ground) control and does not fit any specific base map. The map depicts geologic formations, faults, folds, and other information, and is accompanied by explanatory materials that include the geologic unit descriptions, figures, tables, mapping sources, correlation charts, lithologic columns, geologic symbols, and geologic cross sections.This open-file release makes information available to the public that may not conform to UGS technical, editorial, or policy standards; this should be considered by an individual or group planning to take action based on the contents of this report.

Description: This dataset represents the geology of the Escalante 30'x60'quadrangle at 1:100,000 scale. This open-file release makes GIS data available to the public during the review and production period necessary for a formal UGS publication. The map may be incomplete, and inconsistencies, errors, and omissions have not been resolved. While the document is in the review process, it may not conform to UGS standards; therefore, it may be premature for an individual or group to take actions based on its contents. This 2018 provisional open-file geologic map is a partially revised version of a 1999 open-file report (Doelling, H.H., and Willis, G.C., 1999, Interim geologic map of the Escalante and parts of the Loa and Hite Crossing 30' x 60' quadrangles, Garfield and Kane Counties, Utah, Utah Geological Survey Open-File Report 368). The 1999 map was partly compiled from several older geologic maps of various scales and had extensive new mapping and modifications by the authors to fill gaps and resolve inconsistencies. The map is being re-released to correct and improve a few selected geologic features, and to release an interim GIS database.

Description: This dataset represents the geology of the Escalante 30'x60'quadrangle at 1:100,000 scale. This open-file release makes GIS data available to the public during the review and production period necessary for a formal UGS publication. The map may be incomplete, and inconsistencies, errors, and omissions have not been resolved. While the document is in the review process, it may not conform to UGS standards; therefore, it may be premature for an individual or group to take actions based on its contents. This 2018 provisional open-file geologic map is a partially revised version of a 1999 open-file report (Doelling, H.H., and Willis, G.C., 1999, Interim geologic map of the Escalante and parts of the Loa and Hite Crossing 30' x 60' quadrangles, Garfield and Kane Counties, Utah, Utah Geological Survey Open-File Report 368). The 1999 map was partly compiled from several older geologic maps of various scales and had extensive new mapping and modifications by the authors to fill gaps and resolve inconsistencies. The map is being re-released to correct and improve a few selected geologic features, and to release an interim GIS database. However, most map features are not modified from the original and many aspects of the map do not meet modern standards of precision or accuracy. Most significant revisions were made along the western border to better match the recently published geologic map of the Panguitch 30' x 60' quadrangle (Biek and others, 2015b, Geologic map of the Panguitch 30' x 60' quadrangle, Garfield, Iron, and Kane Counties, Utah, Utah Geological Survey Map 270DM) and along the western part of the northern border to better match an interim geologic map of part of the Loa 30' x 60' quadrangle (Biek and others, 2015a, Interim geologic map of the Western Loa 30' x 60' quadrangle, Garfield, Piute, and Wayne Counties, Utah, Utah Geological Survey Open-File Report 648). A few unit names were updated and revised ages and selected other information were added to a few geologic unit descriptions. Spatial placement of most other geologic features is based on methods used in the 1980–90s and does not match modern standards. The Escalante 30' x 60' quadrangle straddles the high plateaus and western Colorado Plateau of south-central Utah and extends from Johns Valley near Bryce Canyon National Park across the Escalante Mountains, Kaiparowits Plateau, Escalante River basin, Circle Cliffs, and Water Pocket Fold, and includes part of Capitol Reef National Park. Exposed rocks range from Permian White Rim Sandstone and Kaibab Formation to Tertiary volcanic tuffs derived from the Marysvale volcanic field. Johns Valley near the western border is a deep graben. The rest of the quadrangle is dominated by broad north- to north-northwest-trending asymmetric folds with generally steep eastern limbs; the largest and most famous is the Waterpocket Fold that forms the heart of Capitol Reef National Park. Surficial alluvial, mass movement, colluvial and eolian deposits are abundant, especially in the higher elevations. This mapping is intended for use at 1:100,000 or smaller scale. This map was produced using various topographic and photographic base maps for spatial (ground) control and does not fit any specific base map. The map depicts geologic formations, faults, folds, and other information, and is accompanied by explanatory materials that include the geologic unit descriptions, figures, tables, mapping sources, correlation charts, lithologic columns, geologic symbols, and geologic cross sections.This open-file release makes information available to the public that may not conform to UGS technical, editorial, or policy standards; this should be considered by an individual or group planning to take action based on the contents of this report.

Description: This digital dataset represents the geology of the east half of the Salina 30' x 60' quadrangle at 1:62,500 scale. This open-file release makes GIS data available to the public during the review and production period necessary for a formal UGS publication. The map may be incomplete, and inconsistencies, errors, and omissions have not been resolved. While the document is in the review process, it may not conform to UGS standards; therefore, it may be premature for an individual or group to take actions based on its contents.The Salina 30' x 60' quadrangle is located in central Utah and covers a large area that includes the San Rafael Swell, the Wasatch Plateau, the I-70 corridor, and the Fish Lake Plateau. The boundaries of the map are 111° to 111.5° W and 38.5° to 39° N.Tertiary bedrock units include the Flagstaff Formation and dikes, sills, and local volcanic flows and ash-flow tuffs. The North Horn Formation is of Tertiary-Cretaceous age. Cretaceous units are the Castlegate and Blackhawk Formations; Star Point Sandstone; Blue Gate, Emery, Ferron, and Tununk Members of the Mancos Shale; Dakota (Naturita) Formation; and Mussentuchit, Short Canyon, Ruby Ranch, and Buckhorn Members of the Cedar Mountain Formation. Jurassic units are the Brushy Basin, Salt Wash, and Tidwell Members of the Morrison Formation; Summerville Formation; Curtis Formation; Entrada Sandstone; Winsor and combined lower members of the Carmel Formation; Temple Cap Formation; Navajo Sandstone; and Kayenta Formation. The Wingate Sandstone is Jurassic-Triassic in age. Triassic units are the upper members (Church Rock, Owl Rock, and Petrified Forest) and lower members (Moss Back, Monitor Butte, and Temple Mountain) of the Chinle Formation, and the Moody Canyon Member of the Moenkopi Formation. Quaternary deposits include alluvial, pediment, alluvial-terrace, landslide, talus, eolian, and lacustrine unconsolidated sediments. The eastern part of the map area sprawls across the western limb of the San Rafael Swell, a broad early Tertiary-Cretaceous Laramide anticlinal uplift. The southern part of the quadrangle includes the Last Chance Desert and the northernmost part of Capitol Reef National Park. Most of the strata in the map area dip to the northwest and strike northeast-southwest.

Description: This 1:62,500-scale digital dataset represents geologic features that cover the Hite Crossing-lower Dirty Devil River area and is one of several maps recently produced by the Utah Geological Survey that together provide complete printed and Geographic Information System (GIS) geologic map coverage of Glen Canyon National Recreation Area. The map area includes the confluence and deep canyons of the Colorado and Dirty Devil Rivers, which are crossed by State Highway 95, completed in 1966 and later designated as Utah's Bicentennial Highway. Exposed strata range from the Pennsylvanian Honaker Trail Formation to the Jurassic Carmel Formation, but deep reddish-brown, orangish-red, and tan Permian to Jurassic strata that create popular colorful scenery near Lake Powell dominate the area. Overall, strata dip gently to the west and are cut by a swarm of mostly northwest-trending faults, most with offsets of a few feet to a few tens of feet. Surficial deposits include broad areas of eolian sand, alluvial fans, river and stream terrace gravels, and several large landslides in the Chinle and overlying formations. During high water levels, Lake Powell extends far up the canyons of both rivers, but when the lake is down about 30 meters (100 feet) or more it does not extend into the map area and the rivers incise into large deltaic mudflats.

Description: This GIS dataset is reproduced from: “Best, M.G., Morris, H.T., Kopf, R.W., and Keith, J.D., 1987, Geologic map of the southern Pine Valley area, Beaver and Iron Counties, Utah: U.S Geological Survey Miscellaneous Investigations Series Map I-1794, 1 plate, scale 1:50,000.” The map covers four standard 7.5'quadrangles in southwestern Utah: Observation Knoll, The Tetons, Bible Spring, and Mountain Spring Peak.The GIS dataset was completed by David MacKay, Nathan Rau, and Jared Brabazon, students at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, a geologist with the Utah Geological Survey.The UGS appreciates the volunteered time and effort of Brigham Young University students David MacKay, Nathan Rau, and Jared Brabazon who produced the GIS data for this project under the guidance of Brigham Young University professor Eric Christiansen.The southern Pine Valley area is in the Basin and Range Province of southwestern Utah and is dominated by north-south-trending mountain ranges and broad valleys. This map covers the southern end of Pine Valley where the topographic highs of the Wah Wah Mountains and Blawn Mountain area extend southwest into the Broken Ridge, North Peaks, and Indian Peak Range areas to encapsulate the southern end of Pine Valley. The ranges expose Middle to Upper Cambrian and Middle Ordovician to Upper Mississippian sedimentary rocks that compose the upper plate of the Blue Mountain thrust fault. The upper plate of the Blue Mountain thrust fault is cut by the Tetons and Dry Canyon thrust faults in the northwest portion of the map. In the north-central portion of the map, an erosional window in the lower plate of the Blue Mountain thrust exposes Jurassic and Triassic(?) Navajo Sandstone. All thrust faulting within the map area is a result of contractional deformation that occurred during the Cretaceous Sevier orogeny. Oligocene to Miocene volcanic, volcaniclastic and minor amounts of intrusive rocks unconformably overlie and intrude Paleozoic rocks. North- to northeast-striking normal faults cut Paleozoic and Cenozoic rocks and are the result of the Tertiary Basin and Range extension. The map area is cut from southwest to northeast by the Bible Spring fault zone, an anastomosing system of northeast-striking, Tertiary normal faults. The Bible Spring fault zone does not cut the younger Miocene rhyolite member of the Steamboat Mountain Formation (Tsr) but is likely the conduit for hydrothermally-altering fluids which created a geochemical anomaly within the unit. Quaternary alluvium covers the topographically lower portions of the map area. This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match the UGS 2018 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1987 and does not meet all modern cartographic, spatial control, or geologic standards. Line and point attributes and symbology were selected from current (2018) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted on the original map, but are not an exact match, as noted below. ContactsOriginal attribute is “Contact.” These lines are now depicted as “Contact, well located.”Normal FaultsOriginal attribute is“High-angle fault – Dotted where concealed; bar and ball on downthrown side where displacement is certain.” These lines are now depicted as “Fault, normal, well located” or “Fault, normal, concealed.”General faultsLine types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, unknown, well located” or “Fault, unknown, concealed.”Thrust FaultsOriginal attribute is “Thrust fault – Sawteeth on upper plate; dotted where concealed.” These lines are now depicted as “Fault, thrust, type1, well located”where older rocks are faulted over younger rocks.FoliationOriginal attribute is “Strike and dip of compaction foliation in tuffs.” These points are now depicted as “Foliation, inclined, field measured” or “Foliation, horizontal.”Units – Descriptions/Names/AgesMap is not modified from original source map even in locations where newer interpretations may exist.

North- to northeast-striking normal faults cut Paleozoic and Cenozoic rocks and are the result of the Tertiary Basin and Range extension. The map area is cut from southwest to northeast by the Bible Spring fault zone, an anastomosing system of northeast-striking, Tertiary normal faults. The Bible Spring fault zone does not cut the younger Miocene rhyolite member of the Steamboat Mountain Formation (Tsr) but is likely the conduit for hydrothermally-altering fluids which created a geochemical anomaly within the unit. Quaternary alluvium covers the topographically lower portions of the map area. This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match the UGS 2018 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1987 and does not meet all modern cartographic, spatial control, or geologic standards. Line and point attributes and symbology were selected from current (2018) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted on the original map, but are not an exact match, as noted below. ContactsOriginal attribute is “Contact.” These lines are now depicted as “Contact, well located.”Normal FaultsOriginal attribute is“High-angle fault – Dotted where concealed; bar and ball on downthrown side where displacement is certain.” These lines are now depicted as “Fault, normal, well located” or “Fault, normal, concealed.”General faultsLine types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, unknown, well located” or “Fault, unknown, concealed.”Thrust FaultsOriginal attribute is “Thrust fault – Sawteeth on upper plate; dotted where concealed.” These lines are now depicted as “Fault, thrust, type1, well located”where older rocks are faulted over younger rocks.FoliationOriginal attribute is “Strike and dip of compaction foliation in tuffs.” These points are now depicted as “Foliation, inclined, field measured” or “Foliation, horizontal.”Units – Descriptions/Names/AgesMap is not modified from original source map even in locations where newer interpretations may exist.

Description: This GIS dataset is reproduced from: “Best, M.G., Morris, H.T., Kopf, R.W., and Keith, J.D., 1987, Geologic map of the southern Pine Valley area, Beaver and Iron Counties, Utah: U.S Geological Survey Miscellaneous Investigations Series Map I-1794, 1 plate, scale 1:50,000.” The map covers four standard 7.5'quadrangles in southwestern Utah: Observation Knoll, The Tetons, Bible Spring, and Mountain Spring Peak.The GIS dataset was completed by David MacKay, Nathan Rau, and Jared Brabazon, students at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, a geologist with the Utah Geological Survey.The UGS appreciates the volunteered time and effort of Brigham Young University students David MacKay, Nathan Rau, and Jared Brabazon who produced the GIS data for this project under the guidance of Brigham Young University professor Eric Christiansen.The southern Pine Valley area is in the Basin and Range Province of southwestern Utah and is dominated by north-south-trending mountain ranges and broad valleys. This map covers the southern end of Pine Valley where the topographic highs of the Wah Wah Mountains and Blawn Mountain area extend southwest into the Broken Ridge, North Peaks, and Indian Peak Range areas to encapsulate the southern end of Pine Valley. The ranges expose Middle to Upper Cambrian and Middle Ordovician to Upper Mississippian sedimentary rocks that compose the upper plate of the Blue Mountain thrust fault. The upper plate of the Blue Mountain thrust fault is cut by the Tetons and Dry Canyon thrust faults in the northwest portion of the map. In the north-central portion of the map, an erosional window in the lower plate of the Blue Mountain thrust exposes Jurassic and Triassic(?) Navajo Sandstone. All thrust faulting within the map area is a result of contractional deformation that occurred during the Cretaceous Sevier orogeny. Oligocene to Miocene volcanic, volcaniclastic and minor amounts of intrusive rocks unconformably overlie and intrude Paleozoic rocks. North- to northeast-striking normal faults cut Paleozoic and Cenozoic rocks and are the result of the Tertiary Basin and Range extension.

The GIS dataset was completed by Laura Riley and Gerrit Gardner, students at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, a geologist with the Utah Geological Survey.The UGS appreciates the volunteered time and effort of Brigham Young University students Laura Riley and Gerrit Gardner who produced the GIS data for this project under the guidance of Brigham Young University professor Eric Christiansen.The southern Needle Range area is in the Basin and Range Province of southwestern Utah and is dominated by north-south-trending mountain ranges and broad valleys. In the central part of the map, Lower Ordovician through Lower Pennsylvanian sedimentary rocks are exposed in four unique structural settings. From northwest to southeast, these Paleozoic sedimentary outcrops are: (1) a section of Ordovician and Devonian(?) rocks that are part of an intracaldera landslide, (2) a low-angle attenuation fault separating an incomplete section of Pennsylvanian Callville Formation from the Mississippian Monte Cristo Limestone, (3) steeply dipping and overturned Ordovician and Silurian rocks thrust over Mississippian and Pennsylvanian rocks, and (4) a section of Silurian and Devonian rocks that dip uniformly northwest. Thrust faulting is a result of contractional deformation that occurred during the Cretaceous Sevier orogeny. The attenuation faulting could have occurred during the Sevier orogeny or during orogenic relaxation immediately following the Sevier orogeny. Oligocene to Miocene volcanic, volcaniclastic and minor amounts of intrusive rocks unconformably overlie and intrude Paleozoic rocks. The entire map lies within the collapsed Indian Peak caldera. A portion of the topographic wall of the White Rock caldera, one of the sources of the numerous volcanic units within the area, is present in the south-central part of the map area. Northwest- to northeast-striking normal faults cut Paleozoic–Cenozoic rocks and are the result of the Tertiary Basin and Range extension.

A sediment-veneered pediment extending a few kilometers into Pine Valley is present on the east side of the ranges.This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users. The GIS dataset reproduces the original source map as close as reasonably possible; however, some geologic decisions were made to resolve cartographic problems such as inconsistent faults and incomplete polygons. We changed some geologic line symbols to better match the UGS 2018 data model. While the map is considered a good representation of the geology of the map area, users should be aware that it was produced in 1987 and does not meet all modern cartographic, spatial control, or geologic standards. Line and point attributes and symbology were selected from current (2018) UGS schema and do not necessarily match the intent of the original map. Selected attributes most closely represent the general geologic interpretation depicted on the original map, but are not an exact match, as noted below. ContactsOriginal attribute is “Contact – Dashed where approximately located or inferred on cross sections.” These lines are now depicted as “Contact, well located.”Normal FaultsOriginal attribute is “High-angle fault – Dotted where concealed. Bar and ball on downthrown side.” These lines are now depicted as “Fault, normal, well located” or “Fault, normal, concealed.”General faultsLine types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, unknown, well located” or “Fault, unknown, concealed.”Attenuation FaultsOriginal attribute is “Younger-on-older attenuation fault.” These lines are now depicted as “Fault, attenuation, exposed” where younger rocks are faulted over older rocks.FoliationOriginal attribute is “Strike and dip of compaction foliation in tuff and flow layering in intrusive bodies.” These points are now depicted as “Foliation, inclined, field measured” or “Foliation, horizontal.”Hydrothermal AlterationThe original source map shows areas of hydrothermal alteration denoted by a black stipple pattern on top of the host rock fill color. These areas are now denoted with a separate polygon that is attributed with a unit symbol of “ha” and unit name of “Hydrothermal alteration.” These hydrothermal alteration polygons overlie the host rock polygon, have a transparent background and a black stipple pattern, and are a unique feature class.Units – Descriptions/Names/AgesMap is not modified from original source map even in locations where newer interpretations may exist.

Description: This GIS dataset is reproduced from: “Best, M.G., Hintze, L.F., and Holmes, R.D., 1987, Geologic map of the southern Mountain Home and northern Indian Peak Ranges (central Needle Range), Beaver County, Utah: U.S Geological Survey Miscellaneous Investigations Series Map I-1796, 1 plate, scale 1:50,000.” The map covers four standard 7.5' quadrangles in southwestern Utah: Lopers Spring, Sawtooth Peak, Miners Cabin Wash, and Buckhorn Spring. The GIS dataset was completed by Anthony Blackham and Gerrit Gardner, students at Brigham Young University, and final GIS review and preparation for public release were completed by Zach Anderson, a geologist with the Utah Geological Survey.The UGS appreciates the volunteered time and effort of Brigham Young University students Anthony Blackham and Gerrit Gardner who produced the GIS data for this project under the guidance of Brigham Young University professor Eric Christiansen.The map area is in the Basin and Range Province of southwestern Utah and is dominated by north-south-trending mountain ranges and broad valleys. The southern part of the Mountain Home and northern part of the Indian Peak Range expose a nearly complete section of Middle Cambrian through Lower Mississippian sedimentary rocks that generally dip east. Uppermost Ordovician and Silurian rocks in the north part of the map are cut by numerous attenuation faults that are subparallel to bedding and are thought to be the result of thin-skinned detachment faulting that occurred during relaxation of the thrust belt sometime after the Late Cretaceous Sevier orogeny. Late Eocene to late Oligocene volcanic and volcaniclastic rocks unconformably overlie Paleozoic rocks. Portions of the Pine Valley and Indian Peak calderas, the sources of multiple volcanic units in the map area, are present within the central and southern portion of the map. North- to northeast-striking normal faults are a result of the Tertiary Basin and Range extension. The west side of the Indian Peak Range is cut by a major down-to-the-west normal fault that bounds the west side of the range and the east side of Hamlin Valley. A sediment-veneered pediment extending a few kilometers into Pine Valley is present on the east side of the ranges.This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users.

Description: This GIS dataset is reproduced from: “Best, M.G., Lemmon, D.M., and Morris, H.T., 1989, Geologic map of the Milford quadrangle and east half of the Frisco quadrangle, Beaver County, Utah: U.S Geological Survey Miscellaneous Investigations Series Map I-1904, 1 plate, scale 1:50,000.” The map covers six standard 7.5' quadrangles in southwestern Utah: Frisco, Milford NW, Milford, Milford Flat, Picacho Peak, and White Mountain, and a narrow strip of the eastern portions of Frisco SW and Wallaces Peak. The GIS dataset was completed by Andrew Lawrence, Dustin Joe, Patrick Lowe, Lawrence Kellum, and Kade Carlson, students at Utah Valley University, and final GIS review and preparation for public release were completed by Zach Anderson, a geologist with the Utah Geological Survey.The UGS appreciates the volunteered time and effort of Utah Valley University students Andrew Lawrence, Dustin Joe, Patrick Lowe, Lawrence Kellum, and Kade Carlson who produced the GIS data for this project under the guidance of Utah Valley University professor Suzanne Walther.The southern Milford-Frisco area is in the Basin and Range Province of southwestern Utah and is dominated by north-south-trending mountain ranges and broad valleys. The prominent ranges in this map area are the San Francisco Mountains, Beaver Lake Mountains, Rocky Range, Star Range, and the Shauntie Hills. On the west side of the map, the Wah Wah Valley bounds the west side of the San Francisco Mountains and Shauntie Hills. On the east side of the map, the Escalante desert bounds the east side of the Beaver Lake Mountains, Rocky Range, and Star Range. In the Star Range, Lower Devonian through Lower Jurassic sedimentary rocks are thrust over Triassic and Jurassic rocks by the Blue Mountain thrust. In the Shauntie Hills, the Blue Mountain thrust is not exposed but the Devonian and Mississippian rocks that crop out within the range are likely part of the upper plate of the fault. In the southern part of the San Francisco Mountains, a thrust fault places Late Cambrian through Middle Ordovician rocks over Permian and Pennsylvanian rocks. This thrust fault is likely the Blue Mountain thrust; however, exposures of the fault are not continuous between ranges so correlation of these faults is speculative. In the Rocky Range, undifferentiated Paleozoic rocks are thrust over Permian rocks. The thrust faulting within the map area is a result of contractional deformation that occurred during the Cretaceous Sevier orogeny. The numerous east-west-striking faults in the Star Range likely accompanied and accommodated thrust faulting. Oligocene to Miocene volcanic, intrusive, and volcaniclastic rocks unconformably overlie and intrude Paleozoic and Mesozoic rocks. Iron and copper mineralization are associated with emplacement of the larger bodies of intrusive rock. Dominantly north- to northeast-striking normal faults cut Paleozoic-Cenozoic rocks and are the result of Tertiary Basin and Range extension. A zone of east-striking normal faults cuts the south-central part of the Shauntie Hills and southern part of the Star Range. A large Tertiary normal fault bounds the east side of Wah Wah Valley. Smaller faults near Copper Gulch, likely related to the range-bounding fault, cut Quaternary alluvium. This dataset was produced as part of a UGS multi-decade effort to provide statewide intermediate-scale (approximately 1:50,000 to 1:100,000) GIS data to the public, federal to local government agencies, educational groups, exploration and development companies, and other map users.

These lines are now depicted as “Fault, normal, well located”; “Fault, normal, approximately located”; or “Fault, normal, concealed.”Geophysical FaultsOriginal attribute is “High-angle fault – Dashed where approximately located; dotted where concealed; groups of three dots where inferred and concealed; bar and ball on downthrown side.” These lines are now depicted as “Fault, geophysical, gravity.”Strike-slip FaultsLine types do not have a description in the explanation of the original map. These lines are now depicted as “Fault, strike-slip, right-lateral, well located”; “Fault, strike-slip, right-lateral, approximately located”; “Fault, strike-slip, left-lateral, well located”; or “Fault, strike-slip, left-lateral, concealed.”Thrust FaultsOriginal attribute is “Thrust fault – Dotted where concealed; sawteeth on upper plate.” These lines are now depicted as “Fault, thrust, type 1, well located” or “Fault, thrust, type 1, concealed.”General FaultsLine types do not have a description in the explanation of the original map.
