Helena National Forest dominates the southwestern corner of this topographic survey, where a high-elevation landscape is defined by its mining history and remote drainage systems. The presence of the Thompson Gulch Guard Sta serves as a central point for managing this rugged timberland. Along the steep slopes of Camas Ridge, the industrial heritage of Meagher County is evident through several named workings, including the Porcupine Mine, Snowbank Mine, and Bigler Mine.
