1952 Map of Torrey Mountain

About this map

The Pioneer Mountains dominate this high-altitude landscape within the Beaverhead National Forest, defined by a series of prominent peaks and glacial cirques. Elevation reaches its peak at Tweedy Mountain and Torrey Mountain, where the topography creates a dense network of alpine water bodies including the Gorge Lakes, Glacier Lake, and Torrey Lake. This environment supported a system of early infrastructure and resource extraction, evidenced by the scattered Mine symbols and the established Thief Creek Road and Birch Creek Road. The drainage patterns are intricate, with DuBois Creek, Birch Creek, and Thief Creek carving deep paths through the terrain. Numerous smaller basins hold named lakes such as Minneopa Lake and Boatman Lake, reflecting the geological complexity of the range before modern development altered these backcountry routes.
