Gallagher Mountain and the adjacent Gallagher Butte dominate the high terrain of Beaverhead County in this 2014 survey. The landscape is defined by its sophisticated water management and drainage systems, where the E Bench Canal and Canyon Ditch move water through the northern flats near Lovells Lake. This high-country geography shows a complex network of canyons and gulches, including Small Horn Canyon, Mass Canyon, and Little Basin Canyon, which channel seasonal runoff toward Sheep Creek and the various forks of Gallagher Creek. The presence of several named peaks like Retort Mountain and Jim Brown Mountain suggests a landscape historically utilized for livestock grazing and irrigation, where high-altitude ridges give way to developed agricultural infrastructure at the base of the mountains.
