About this map

Gallagher Mtn and Jim Brown Mtn anchor the high country of Beaverhead County in this 2017 survey. The landscape is defined by a series of steep drainages including Mass Canyon, Little Basin Canyon, and Small Horn Canyon, which flow eastward toward the Sheep Cr drainage. Higher elevations are marked by distinctive peaks such as Retort Mtn and Gallagher Butte, while the lower northern sections show more human-centric engineering in the form of Canyon Ditch and access roads like Steffonic Ln and Carrigan Ln.

Water resources are concentrated in the north and south, with Lovells Lake and its associated Lovells Gulch near the upper boundary, and Horseshoe Lake situated near the headwaters of Middle Fork Gallagher Cr to the south. The mapping of East Fork Clark Canyon suggests the complex topography of this portion of southwest Montana, where land use is split between natural drainage basins and high mountain summits.
