1967 Map of Leatherman Peak

About this map

The high ridges of the Lost River Range dominate this mid-century survey, showcasing some of Idaho's most significant alpine terrain within the Challis National Forest. Elevations culminate at Leatherman Peak and Mount Breitenbach, where the topography drops sharply into deep drainage basins. The map documents the headwaters of the Pahsimeroi River, including the West Fork Pahsimeroi River and East Fork Pahsimeroi River. While the higher elevations are defined by passes like Leatherman Pass, the lower southern slopes transition into more accessible areas such as Cedar Creek Bar. Evidence of human activity is limited to a remote Pack Trail in the north and a single Prospect near Lone Cedar Creek, suggesting a landscape used primarily for grazing, watershed management, and small-scale mining explorations rather than permanent settlement.
