About this map

Challis National Forest dominates this high-altitude landscape, where the Big Lost River begins its course through a complex network of glacial and volcanic terrain. In the heart of the Copper Basin Flat, mining activity is evident at the Copper Basin Mine and numerous unnamed shafts and borrow pits, signaling the area's mineral importance in Custer County. The presence of the Copper Basin F S Station and the Copper Basin Landing Strip underscores the logistical role this basin played for forest management and remote access.

Water and livestock have long shaped the land here, as seen at the Corral Creek Cow Camp near the Corral Creek Road. Rugged geographic features like The Potholes, Antelope Pass, and the peaks of the White Knob Mountains create a high-relief backdrop for the seasonal wetlands of The Swamps. A lonely Telephone Line and various pack trails provide the only modern connectivity through these high mountain canyons.
