About this map

The Big Snowy Mountains dominate this high-elevation landscape within the Lewis & Clark National Forest, where the topography shifts from steep ridges to complex canyon systems. Prominent summits like Greathouse Peak and Old Baldy tower over the surrounding terrain, marking the southern edge of the range near the border of Fergus and Golden Valley counties. This area serves as a significant drainage basin, with the Middle Fork Big Spring Cr and E Fork Big Spring Cr flowing northward, while the Half Moon Cr and Swimming Woman Cr navigate the southern slopes.

Evidence of historical land use and access is visible in the network of forest trails and primitive roads, such as the Wapiti Ridge Trl and Red Hill Rd. These routes provide access to remote features like Stovepipe Canyon, Bowmans Bench, and the narrow passage at Half Moon Pass. The map also details numerous unnamed land parcels (PB blocks), reflecting the complex history of public land survey and management in this part of Montana.
