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. |
