1964 Map of Washington Peak

About this map

White Cloud Peaks and the high basins of Custer County dominate this 1964 field-checked survey, revealing a landscape defined by industrial extraction and high-altitude water systems. The map captures the boundary between the Challis National Forest and Sawtooth National Forest, illustrating how earlier mining efforts like the Aztec Mine and Black Rock Mine were situated among the peaks. A network of high-mountain waters, including the Champion Lakes, Phyllis Lake, and Fourth of July Lake, are shown alongside the drainage of Fourth of July Creek and Warm Springs Creek. The presence of a Jeep Trail and various foot trails through Washington Basin and Ants Basin suggests the post-war transition toward recreational use in areas formerly accessed primarily for their mineral potential.
