Boulder Mountains topography dominates this high-altitude survey of the central Idaho wilderness. At the headwaters of the East Fork Salmon River, the map captures a landscape defined by seasonal water flow and mineral prospecting. Evidence of early extractive industry is visible near the Custer Co Blaine Co boundary, where several Mines are located on the slopes below Galena Peak. The area is interlaced with a network of Pack Trails and Jeep Trails, indicating a period when access to these remote heights was limited to rugged vehicles and livestock. Notable drainage systems like Germania Creek and Washington Creek feed into the Salmon River system, while Washington Lake sits as a significant alpine feature in the northwest corner. This mapping effort, field-checked in 1970, provides a detailed view of the Sawtooth National Recreation Area before more modern infrastructure changes reached these peaks.
