West Pryor Mountain dominates this portion of the Montana landscape, where the Crow Indian Reservation Boundary marks a significant jurisdictional divide across the high-altitude terrain. The topography is defined by the steep descent of Black Canyon and the winding course of Section House Draw, which channel seasonal water toward the lower valleys. This 1966 aerial survey reveals a landscape largely shaped by its natural drainage patterns, including the headwaters of North Fork Fivemile Creek and Middle Fork Fivemile Creek. The area’s sparse infrastructure is concentrated around industrial markers like the Pipelines near Pryor Summit and Gap. Isolated water sources such as Bird Spring and Sand Spring provide critical reference points for land use in this arid, high-country environment.
