It is situated nine miles northeast of the community of Ouray, in the Uncompahgre Wilderness, on land managed by Uncompahgre National Forest. It is part of the San Juan Mountains which are a subset of the Rocky Mountains, and is situated west of the Continental Divide. Coxcomb ranks as the 171st-highest peak in Colorado, and topographic relief is significant as the south aspect rises 2,000 feet (610 meters) above Wetterhorn Basin in approximately one mile, and 4,400 feet (1,340 meters) above Cow Creek in three miles. Neighbors include Precipice Peak 2.7 miles to the north, Matterhorn Peak 2.3 miles to the east-southeast, and nearest higher neighbor Wetterhorn Peak 1.8 mile to the southeast.
