About this map

Custer National Forest and Gallatin National Forest meet at the high-altitude boundary of Montana and Wyoming on this 2020 map. The landscape is defined by the Beartooth Mountains and the sprawling Beartooth Plateau, where massive peaks like Castle Mtn and Sundance Mtn dominate the skyline. This area is a critical hydrological source, feeding the East Rosebud Creek Wild and Scenic River and a dense network of alpine water bodies, including Snowbank Lake, Big Butte Lake, and Otter Lake.

The presence of three different national forests—including the Shoshone National Forest at the southern edge—indicates the convergence of distinct federal management zones in this wilderness. Backcountry access is marked by established paths such as the Farley Lake Loop and Granite Lake Loop, which serve as the primary corridors through the jagged terrain between peaks like Snowbank Mtn and Summit Mtn.
