2014 Map of Deadman Lake

About this map

The Beaverhead Mountains form a high-altitude spine along the Continental Divide, where the border between Montana and Idaho follows the crest of the range. This 2014 survey documents the wilderness interface between the Beaverhead National Forest and Targhee National Forest. Historically significant as a high-mountain crossing, Bannack Pass serves as a primary transit point across the jagged ridgeline. The landscape is defined by its drainage basins, with Deadman Lake and Divide Creek Lake tucked into the high basins. Water flows through steep canyons via Deadman Cr and Nicholia Cr, while the Fritz Creek Trl provides one of the few designated routes through this high-elevation terrain. This modern survey shows how the Public Land Survey System grid interacts with the natural topography, marking boundaries like the Beaverhead Co Clark Co line.
