About this map

The Pioneer Mountains define the high country of this Montana landscape, where the Beaverhead National Forest meets a network of deeply etched gulches and canyons. The site of Ermont Mill sits in the lower elevations of the southern quadrangle, marking a historical point of processing for the region's mineral wealth. Moving north, the terrain rises toward peaks like Black Mtn and significant geological features such as Red Butte.

Water management is evident in the presence of the Kelley Reservoir and various high-country springs, including Argenta Spring and Taylor Spring. The map documents a rugged drainage system shaped by Rattlesnake Cr and Cottonwood Cr, illustrating how early infrastructure followed the natural contours of the land. Access to these remote areas is maintained via established routes like Kelly Reservoir Rd and Badger Pass Rd, which thread through the namesake Ermont Gulch.
