It is the highest summit of the Mosquito Range, and the eleventh-highest summit in the contiguous United States. Old mine roads zigzag across a nearby slope at the top of Park County.

Overlook of the confluence of the Dolores and San Miguel rivers in Montrose County. Reddish-orange cliffs of the early Jurassic Wingate Sandstone form the tall cliffs above the river level. Abundant rockfall debris with many house-sized boulders is common along the Dolores River. The darker red slope-forming rocks above the massive eolian Wingate cliffs is the Jurassic Kayenta Formation. The overlying Jurassic Entrada, Summerville, and Morrison formations are seen in ascending order in the background, highlighted by the setting sun. Photo credit: Nate Rogers for the CGS.
