About this map

Beaverhead National Forest encompasses this high-elevation landscape, where the Gravelly Range dominates the western half of the terrain. The map captures a wilderness area defined by significant geological features like Big Horn Mountain and Fossil Ridge, alongside the deeply carved Beartrap Canyon. Unlike more settled regions, the human footprint here is limited to high-altitude outposts and resource management, evidenced by the presence of Sheep Camp and the winding Gravelly Range Rd.

Water systems originate in these peaks, with the headwaters of Ruby Cr, Wall Cr, and Standard Cr flowing through steep basins. Notable localized water features include Wall Cr Lake and the Kelly Reservoir, which support the high-country ecosystem. The survey also identifies family-named and descriptive landmarks like Lazyman Hill and Specimen Butte, providing essential context for researchers of Montana's mountainous backcountry during the early 21st century.
