Geologic Map of the Heber City Quadrangle, Wasatch and Summit Counties, Utah (M-295DM)

By: Robert F. Biek

The Heber City quadrangle includes the northern half of Heber Valley and much of Jordanelle Reservoir. Parts of the Park City mining district and Deer Valley Resort, and much of Wasatch Mountain State Park, occupy the northwestern part of the quadrangle. Geology in the west half of the quadrangle is dominated by Paleozoic- and Mesozoic-age shallow-marine and continental strata in the Wasatch Range. These rocks host late Eocene- to early Oligocene-age shallow intrusions collectively called the Park City porphyries, the source of mineralization in what was once one of the West’s most important silver-lead-zinc mining districts. Volcanic rocks derived from these and other nearby shallow intrusions dominate the east half of the map area. The town of Midway, at the west edge of Heber Valley, is well known for its hot springs and calcareous tufa deposits. Numerous hiking, mountain biking, and Nordic ski trails make this a popular year-round recreational area.
