Geologic map of the Clearfield 7.5' quadrangle, Davis County, Utah (MP 05-4)

By: D. Sack

The Clearfield quadrangle lies on the eastern shore of Great Salt Lake about 15 miles southwest of Ogden. Elevations increase across the quadrangle from about 4,196 feet beneath Farmington Bay in the southwestern corner of the map to deposits of the Provo-level Weber River delta of Lake Bonneville at about 4,757 feet in the northeastern corner of the map. The quadrangle consists of an extensive slope composed entirely of unconsolidated late Quaternary deposits that are portrayed on the geologic map in ten map units. The geologic map also indicates preserved portions of two well-developed Great Salt Lake shorelines, the Gilbert shoreline at 4,245 feet and a high Holocene shoreline that is found between 4,217 and 4,220 feet. No bedrock crops out and no fault scarps were observed on the quadrangle. Sand and salt constitute the principal geologic resources. Significant potential geologic hazards are primarily related to ground shaking, liquefaction, and mass wasting that could accompany earthquakes generated along the nearby Wasatch fault zone.
