About this map

Bridger National Forest dominates this high-altitude landscape, where the Bridger Wilderness Boundary separates the forest from protected wilderness areas. The terrain is defined by an intricate network of glacial lakes and alpine waterways, including the expansive Raid Lake, Silver Lake, and the remote Star Lake. Prominent landmarks such as Mitchells Nipple rise above the basin, providing orientation points for travelers navigating the extensive backcountry trail system.

Transportation through this roadless territory relies on historical routes like the Highline Trail and Lowline Trail, which connect various drainage basins. The map illustrates a complex aquatic system where the Middle Fork Boulder Creek and numerous smaller tributaries drain the snow-fed basins. This survey details the landscape after the 1964 Wilderness Act, showing the preserved state of the Bridger Wilderness and its primitive access routes including the Chilcoot Trail and Sage Basin Trail.
