Briston Cem and the western edge of the Big Hole Valley define this landscape in the southern Bitterroot Range. The terrain is marked by a network of drainage systems including Swamp Creek, Moose Creek, and Mifflin Creek, which flow toward the more open ranching country to the east. Modern access through these drainages is provided by gravel routes like Gibbonsville Rd and Twin Lakes Rd, tracing the paths between mountain slopes and the valley floor. Toward the west, the land rises sharply, with Hirschy Reservoir serving as a significant water management feature for the region's agricultural interests. This 2024 survey documents the persistence of isolated family landmarks and the established road network that connects these high-elevation water sources to the surrounding cattle-ranching territory of Beaverhead County.
