GEOLOGIC MAP OF THE WEST MOUNTAIN QUADRANGLE, UTAH COUNTY, UTAH
Donald L. Clark
The West Mountain quadrangle covers West Mountain and parts of Utah and Goshen Valleys along the Interstate 15 corridor. Improvements were made to the bedrock structure and stratigraphy, and to mapping of Quaternary surficial deposits. The mountain consists of folded and faulted Paleozoic strata, largely of the Oquirrh Group. The valleys are mostly covered by Quaternary deposits related to the Bonneville lake cycle, as well as by some younger deposits of Utah Lake and other surficial processes. A large aggregate quarry is located at the south end of the mountain at Keigley. This map is part of ongoing work by the UGS to complete a regional-scale map of the Provo 30′ x 60′ quadrangle.
