About this map

Phi Kappa Mines and scattered prospects characterize this high-altitude landscape in the late 1960s, marking a region defined by mineral exploration and steep alpine terrain. The area serves as a significant intersection of the Challis National Forest and Sawtooth National Forest, with the boundary between Custer and Blaine counties cutting through the Pioneer Mountains.

Glacial activity is evident in the numerous high-basin water bodies, including Washington Lake, Boulder Lake, and Kane Lake. A network of historic transportation routes, such as the Summit Trail and various pack trails, connects remote landmarks like The Devils Bedstead and Handwerk Peak. The presence of the Phi Kappa Campground near Phi Kappa Creek indicates the dual use of the land for both extractive industry and forest recreation during this era.
