1988 Map of Potosi Peak

About this map

Tobacco Root Mountains dominate this high-altitude landscape, characterized by numerous glacial lakes and deep-cut drainages within the Beaverhead National Forest. This 1980s-era study documents a rugged interior where water resources like Hollow Top Lake, Albro Lake, and the Branham Lakes feed into various forks of North Willow Creek and Mill Creek. The map records a legacy of exploration and resource extraction, specifically at the Beulah Mine and New Deal Mine, alongside scattered prospects found throughout the alpine terrain. Recreational and natural features such as Potosi Hot Springs and Potosi Campground illustrate the transition of the area toward seasonal land use. Dramatic peaks including Potosi Peak and Mount Bradley provide vertical context for researchers tracking high-mountain mining claims or backcountry topography.
