2024 Map of Brown Pass

About this map

Fort Peck Lake and the Sutherland Creek Bay define the southern reaches of this landscape, where the Missouri River breaks into a complex of inlets and ridges. Much of the southern terrain is preserved within the Charles M Russell National Wildlife Refuge, a vast area of protected habitat that follows the winding coulees and breaks. The map documents a rugged rangeland characterized by family-named landmarks and water management features, including Shufeldt Ridge and Middle Eighth Ridge. Numerous small reservoirs like Duck Soup Reservoir, Prairie Reservoir, and the Suburban Reservoir illustrate the essential role of artificial water storage in this semi-arid Valley County environment. Further north, the terrain transitions into high ridges such as Van Hook Ridge and passes like Brown Pass, reflecting the traditional pathways across the northern Montana breaks.
