Leatherman Peak and the surrounding high-altitude terrain of the Lost River Range dominate this portion of the Challis National Forest in Custer County. The map documents a watershed divide where the headwaters of the W Fork Pahsimeroi River and E Fork Pahsimeroi River begin their descent. To the south and east, drainage patterns shift toward the Lone Cedar Cr and Upper Cedar Cr systems. The landscape is characterized by significant topographical features such as Donaldson Peak and Mt Breitenbach, alongside alpine water bodies like Merriam Lake and Pass Lake. In the lower elevations, the Cedar Creek Bar and Sawmill Gulch suggest historical land use patterns and access points into these remote mountain reaches. This survey provides a precise look at the 2017 trail and drainage network before any more recent environmental or management changes.
