The Lost River Range is a massive desert fault block range that holds the highest peaks in Idaho. Rising a vertical mile from the valleys on either side, the range is primitive and little explored. Most of the mountaineering and hiking interest in the Lost Rivers is focused on Borah Peak, high point of Idaho, leaving the rest of the range a parched wilderness of steep terrain, talus fields, and deep canyons.
