Morning sun casts light on the reddish-brown and grayish-red sandstone, shale, and siltstone of the Precambrian-age formation of Red Castle in the Uinta Mountain Group. Ice-age glaciers carved the broad valleys and basins of the Uinta Mountains.

The late Precambrian-age Red Castle and Dead Horse Pass Formations, carved by Quaternary glaciers, form the cirque above Henrys Fork basin in the Uinta Mountains. A popular backpacking destination, Henrys Fork basin lies beneath the highest point in Utah, Kings Peak (13,528 feet; on the skyline in middle of photo).

As the Provo River plunges off the south side of the Uinta Mountains along the Mirror Lake Highway, it cascades over innumerable ledges of Precambrian-age Uinta Mountain Group sandstone.

The Kings Peak 7.5-minute quadrangle straddles the crest of the Uinta Mountains in the High Uinta Wilderness Area and contains Kings Peak, Utah’s highest point. The peaks and cliffs are comprised of the newly formalized formations of the Neoproterozoic (late Precambrian) Uinta Mountain Group, which is about 770 to 742 million years old. The basins, basin margins, and cirques are filled with glacial deposits of Smith Fork age-32,000 to 14,000 years ago (Pinedale equivalent). The quadrangle also straddles the anticline crest of the Uinta arch. A series of igneous dikes are exposed in the quadrangle. These dikes cut formations of the Uinta Mountain Group are about 450 to 490 million years old.

Ostler Peak (12,718 feet) is reflected in a meander bend of the Stillwater Fork of the Bear River in the Uinta Mountains. Thousands of years ago glaciers inundated much of the Uinta Mountains, leaving behind long glacier-carved valleys, steep-sided cirques, and jagged peaks.

Francis resident Eric Averett was sitting at his kitchen table Friday morning when he felt a short rumbling and a “boom” sound. That rumbling was a 3.2-magnitude earthquake, which was reported three miles southwest of Woodland.
