Sheep Rock is a 4,564-foot-elevation (1,391-meter) pillar in Grand County, Utah. It is located within Arches National Park and like many of the rock formations in the park, it is composed of Entrada Sandstone, specifically the Slick Rock Member overlaying the Dewey Bridge Member. The tower is 440 feet tall, and is approximately 0.15 mile (0.24 km) from the main park road. Sheep Rock is believed to be a remnant abutment of an ancient fallen arch. Precipitation runoff from Sheep Rock drains to the nearby Colorado River via Courthouse Wash. This landform's descriptive toponym has been officially adopted by the United States Board on Geographic Names.

Climbing

The first ascent of the summit was made October 2, 1986, by Charlie Fowler and Kyle Copeland via the class 5.9 Buggers Banquet route on the west face. Another route is the class 5.8 Virgin Wool, first climbed in November 1986 by Jim Bodenhamer and Sandy Fleming.
