Challis National Forest dominates this high-elevation terrain in Custer County, where the topography reaches its most dramatic heights along the Chinese Wall and The Gunsight. This 2017 survey reveals a landscape defined by sharp glacial features and alpine basins, containing numerous high-altitude water bodies such as Crater Lake, Dike Lake, and Gunsight Lake. The drainage network is complex, with Livingston Cr and Big Boulder Cr flowing through the southern reaches, while the northern edge is bounded by the Salmon River. An interesting historical marker of land use is found at Railroad Ridge, a prominent feature that suggests the high-country travel routes of the past. The map also detail numerous small tributaries like Silver Rule Cr and Carbonate Cr, which cut through the steep slopes of the Salmon River Mountains.
