West Mountain is a range block about 8 miles long by 1 to 2 miles wide in the northeast Great Basin. Most of the mountain consists of Permian and Pennsylvanian marine sedimentary strata capped by probable Late Cretaceous and early Tertiary synorogenic deposits. The southern quarter of the mountain (herein informally referred to as the Quarry Hills) consists largely of Mississippian, Devonian, and Cambrian sedimentary strata. West Mountain was deformed by Late Cretaceous to early Tertiary contractional folding and faulting of the Sevier orogeny, a subsequent extensional collapse (relaxation) event, and late Tertiary to Holocene Basin-and-Range extension.
This geologic map provides basic geologic information necessary to further evaluate geologic hazards and resources in the area, and to gain an understanding of the geology upon which this landscape developed.
