1960 Map of Brown Coulee

About this map

East Blacktail Creek and Brown Coulee dominate this 1960s landscape in Rosebud County, where the topography was carefully documented as part of the Missouri River Basin development program. The map illustrates a water-managed cattle ranching environment defined by a series of engineered catchments, including the Brown Coulee Reservoir, Blacktail Reservoir, and Lower Blacktail Reservoir. For local history researchers, the map provides precise locations for family settlements such as the Sweeter Homestead and Brockel Homestead, alongside the Blacktail Ranch. The rugged breaks of the Badland Coulee cut through the western edge of the sheet, contrasting with the more navigable plains to the east. Sparse industrial markers like Drill Hole 2798 suggest the era's subterranean explorations during this period of rural development.
