Leatherman Peak and the high summits of the Lost River Range dominate this 2013 survey of the Challis National Forest. The map documents a stark alpine landscape defined by massive relief, where drainage systems like the W Fork Pahsimeroi River and E Fork Pahsimeroi River flow north from the heights. High-altitude points such as Mt Breitenbach and Donaldson Peak mark the crest of the range, while Leatherman Pass provides a traditional transition through the steep terrain. Human footprints are sparse but significant, centered on the lower elevations at Cedar Creek Bar. This map is particularly useful for geologists and backcountry historians interested in the drainage patterns of Lone Cedar Cr, Pete Cr, and Upper Cedar Cr as they emerge from the mountain front.
