1963 Map of Challis Creek Lakes

About this map

Challis National Forest dominates this mid-century topographic study, showcasing the high-elevation drainage systems of central Idaho. The map reveals a landscape defined by its industrial and hydraulic history, centered on the Parker Mine and Parker Mill located near Parker Mountain. These sites represent the mining legacy of the region, positioned amongst a complex network of waterways. Multiple drainages, including Warm Spring Creek, Wick iup Creek, and Trapper Creek, flow through the steep terrain, eventually feeding into the Yankee Fork and Challis Creek. Near the eastern boundary, the Challis Creek Lakes sit in a high glacial cirque, illustrating the rugged alpine character of the Salmon River Mountains. The boundary between Custer and Lemhi Counties bisects the northern section of the sheet, providing a precise record of jurisdictional lines as they relate to these mountain crests and stream headwaters.
