2013 Map of Copper Basin Knob

About this map

The high-elevation drainage of the E Fork Big Lost River dominates this Custer County landscape, characterized by the convergence of the Pioneer Mountains and the White Knob Mountains. This 2013 survey captures the seasonal and ranching infrastructure of the region, including the Corral Creek Cow Camp and the high-altitude Copper Basin Airport. The topographical complexity is defined by numerous drainages such as Smelter Canyon and Mine Canyon, which suggest a history of resource exploration within the Challis National Forest. The map centers on the broad Copper Basin Flat, a notable geographical feature surrounded by prominent peaks like Lupine Mtn, Lime Mtn, and the namesake Copper Basin Knob. This area remains a significant corridor for transit through the mountains via Antelope Pass and the primitive Burma Rd.
