1995 Map of Twin Sisters

About this map

The Lewis and Clark National Forest defines the southern portion of this landscape, where the Judith Ranger District National Forest Boundary marks the transition from open drainage basins into protected forest land. This 1995 revision, based on surveys dating back to 1968, highlights the rugged topography of the Twin Sisters and the intricate network of canyons and coulees that shape the regional hydrology. The map identifies the headwaters and seasonal flows of Antelope Creek and its tributary, West Fork Antelope Creek, alongside the deep incisions of Dark Canyon and Buffalo Canyon. A solitary Well is noted near a basin, suggesting limited industrial or agricultural activity in an area largely dominated by the natural drainage patterns of Big Coulee and West Buffalo Creek. This sheet serves as a clear record of land use and forest management boundaries in the mid-1990s Montana wilderness.
