2017 Map of Pinnacle Mountain

About this map

Pinnacle Mtn stands as the central landmark in this high-altitude landscape where the boundaries of Custer National Forest and Gallatin National Forest meet. The geography is defined by a dense network of glacial lakes and alpine drainage systems, most notably the several forks of Wounded Man Cr which carve through the surrounding peaks. Prominent summits including Jordan Mtn, Wildcat Mtn, and Mosquito Peak dictate the flow of water into basins like Horseshoe Basin and onto the Stillwater River. The intersection of Sweet Grass, Stillwater, and Park counties occurs amidst this complex terrain, highlighting the remote nature of these administrative lines. For researchers and geographers, the map provides precise locations for smaller water bodies such as Lake of the Woods, Sunken Rock Lake, and Favonius Lake, illustrating the post-glacial hydrology of the Beartooth region.
