About this map

Missouri River waters and the vast expanse of Fort Peck Lake dominate this central Montana landscape, where the Charles M Russell National Wildlife Refuge preserves a rugged breakland environment. This terrain is defined by a complex network of seasonal drainages, including Dry Coulee, Fisher Coulee, and the curiously named Garrit Schoolhouse Coulee, reflecting a history of isolated rural education in the backcountry.

Evidence of early overland travel and ranching infrastructure is preserved through the Old Musselshell Trl and various livestock-related features such as Big Rock Reservoir and Timber Pit Reservoir. The map illustrates the boundary where Petroleum County meets Phillips County along the river corridor, highlighting the geographic isolation and the vital importance of water management in this arid region of the High Plains.
