1967 Map of Grays Peak

USGS Topo · Published 1971

About this map

The Pioneer Mountains define this high-altitude landscape along the border of Custer and Blaine counties, where mining and wilderness preservation intersect. Surveyed in the late 1960s, the map identifies several significant mineral sites, including the Sunshine Mine, Mascot Mine, and Iron Mine, situated within the rugged drainages of the Sawtooth National Forest. This area serves as a hydrological divide, feeding the Little Wood River and Wildhorse Creek. The terrain is characterized by dramatic peaks like Old Hyndman Pk and the namesake Grays Peak, interspersed with alpine water bodies such as Arrowhead Lake and Windy Lake. A network of pack trails, including the TP Trail, suggests the continued reliance on traditional access routes for forest management and mineral exploration during this era, while the overlap with the Challis National Forest highlights the complex administrative boundaries of Idaho's central wilderness.
