The Four Horns Lake basin dominates this 1960s terrain, situated entirely within the Blackfeet Indian Reservation. This map reveals a complex hydraulic system managed by the Birch Main Canal and the Four Horns Outlet Canal, highlighting the vital role of water management in this part of Montana. The landscape is deeply incised by numerous seasonal drainages, including Jackson Coulee, Tail Feather Coulee, and Rocky Ridge Coulee, which all feed into larger watercourses like Blacktail Creek.
