About this map

Challis National Forest and the Pahsimeroi Mountains define the high-altitude landscape of this 1980s provisional study. The terrain is characterized by a complex network of drainages and peaks, including the prominent Grouse Peak and the high White Hills to the south. The map documents numerous water sources critical to this high-country environment, such as Anderson Spring, Short John Springs, and Burnt Spring.

Evidence of modern infrastructure is sparse, though a Radio Tower sits near Dodge Basin. The drainage patterns are meticulously recorded, showing how the North Fork, Middle Fork, and South Fork of Lawson Creek converge as they move east. These steep gulches, including Pennal Gulch and Gerry Gulch, illustrate the erosion patterns of the northern Pahsimeroi Mountains before modern digital mapping redefined these remote Custer County coordinates.
