1967 Map of Leatherman Peak

About this map

Leatherman Peak and Mount Breitenbach anchor this high-altitude survey of the Lost River Range within the Challis National Forest. The landscape is defined by the headwaters of the West Fork Pahsimeroi River and East Fork Pahsimeroi River, which carve deep drainages through the steep terrain. Evidence of early resource exploration is found at a Prospect near Lone Cedar, while a remote Pack Trail traverses the northern slopes above Sawmill Gulch. To the south, the terrain flattens toward the Cedar Creek Bar, illustrating the transition from the high peaks of the Lost River Range to the alluvial deposits below. This mapping, derived from 1966 aerial photography, provides a precise record of the hydrological divide between the Pahsimeroi and the Cedar Creek drainage systems.
