The Spanish Fork quadrangle covers part of southeast Utah Valley and the adjacent Wasatch Range, and includes the cities of Spanish Fork, Salem, and Payson. Spanish Fork, Peteetneet Creek, Salem Lake, and Spring Lake are the primary hydrologic features. U.S. Interstate Highway 15 extends from northeast to southwest through the map area.

The bedrock of the quadrangle is sedimentary, highly faulted, and Tertiary to Cambrian in age. These sedimentary strata are largely exposed on the southwest, south, and southeast margins of the quadrangle. Most of the surficial deposits in the Spanish Fork quadrangle were deposited by latest Pleistocene Lake Bonneville during the last glacial and overlie coalesced older alluvial fans. The alluvial-fan deposits underlie piedmont slopes on the margin of Utah Valley, and are extensively exposed above the highest Lake Bonneville shoreline on the south margin of the quadrangle between the Provo and Nephi segments of the Wasatch fault zone. 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.
