2013 Map of Pinyon Peak

About this map

Challis National Forest encompasses the high-altitude drainage systems of the Salmon River mountains, where steep drainages and alpine lakes define the wilderness character. The landscape is dominated by Pinyon Peak, a central high point that anchors the surrounding watershed. Water from this summit flows into a network of alpine basins, feeding Pinyon Lake, Blue Lake, and Kidney Lake. The hydrology of this area is complex, with numerous named streams such as Loon Cr and Rabbit Cr carving deep into the terrain. High-elevation landmarks like Feltham Creek Point and the narrow passage of Packer Gulch served as vital reference points for early forest rangers and backcountry travelers. This map captures the remote character of Custer County as it remained into the early 21st century, documented by the U.S. Geological Survey.
