2024 Map of Rocky Coulee

About this map

Rocky Coulee and Black Coulee define the drainage patterns of this northern Montana landscape in Hill County. The terrain is marked by the winding paths of these intermittent waterways, which have carved deep channels into the high plains. Vital water sources like Cockerel Spring provided necessary relief for livestock and early settlers in this arid region, while East Fork Black Coulee drains the northern reaches. The land is organized by a strict rectilinear grid of rural routes, including Inverness Rd S and Co Rd 15 S, which follow the township and range lines established by the Public Land Survey System. This network of roads supports the agricultural operations and remote ranching that characterize the area's modern-day rural economy.
