About this map

The Beaverhead River cuts through the northwest corner of this Beaverhead County landscape, marking the transition from the river valley to the high ridges of the Beaverhead Mountains. Rising steeply above the drainage, peaks such as Jim Brown Mtn, Retort Mtn, and the namesake Gallagher Mtn define a terrain shaped by deep cuts like Mass Canyon and Little Basin Canyon. These features illustrate the dramatic vertical relief that characterizes this section of southwest Montana.

Water sources are scattered throughout these uplands, including Lovells Lake and Horseshoe Lake, providing critical points of interest in an otherwise high-elevation wilderness. While the map is dominated by natural features like Gallagher Butte and Dry Hill, traces of human presence appear in the network of local lanes including Steffonic Ln and Carrigan Ln near the northern boundary. The intricate contouring captures the complex hydrology of the headwaters for Gallagher Cr and the East Fork Clark Canyon.
