Marcum Mountain and Trapper Mountain dominate this western Montana landscape, a region defined by a long history of mineral extraction and cattle ranching. The Blackfoot River carves through the center of the sheet, supported by a network of water management features including the North Helmville Canal and the Copenhagen Dam on Arrastra Creek. The settlement of Coughlin sits as a central point for local activity, while the presence of Steeles Dude Ranch near the northern boundary points to the area's transition into recreational and seasonal land use.
