White Cap Peak

White Cap Peak is an 11899 ft mountain summit located in Custer County, Idaho, United States.

Description
White Cap Peak ranks as the 18th-highest peak in Idaho and is part of the Lost River Range which is a subset of the Rocky Mountains. The mountain is set on land managed by Salmon–Challis National Forest. Neighbors include Leatherman Peak, 1.1 mile to the east, Mount Morrison 2.6 miles to the northwest, Little Regret Peak 3.55 miles east, and Borah Peak, the highest peak in Idaho, is 3.9 miles to the north-northwest. Leatherman Pass, elevation 10,512 ft, is the low point of the saddle midway between White Cap Peak and Leatherman Peak. Precipitation runoff from the mountain's slopes drains southwest to Big Lost River and northeast into headwaters of West Fork Pahsimeroi River. Topographic relief is significant as the summit rises 5,600 ft in four miles above Highway 93 in Big Lost River Valley, and 1,800 ft above Pass Lake in less than one-half mile.
