2024 Map of Three Sisters

About this map

Bob Marshall Wilderness and the Lewis and Clark Range dominate this high-country landscape, where the continental divide serves as a primary geographic axis. This 2024 map documents a complex drainage system flowing away from prominent peaks like Hahn Peak and Lick Mtn, feeding into the Spotted Bear River and Miners Creek. The area is defined by its extensive trail network rather than roads, with the Continental Divide National Scenic Trl traversing the terrain alongside localized routes such as the Three Sisters Trl and the Spotted Bear River Trl. Notable alpine water bodies including Lake Quiet, Sock Lake, and Hart Lake are scattered among the ridges. The survey clearly delineates the boundary between Flathead National Forest and Lewis & Clark National Forest, reflecting the managed wilderness character of the Three Sisters region.
