1950 Map of Shippe Canyon

About this map

The northern boundary of the Fort Peck Indian Reservation dominates the southern portion of this landscape, marking a clear line across the Sheridan County terrain. Mapped during the early 1950s as part of the Missouri River Basin development program, the area is defined by the winding course of Big Muddy Creek and the deep incisions of Shippe Canyon. The local economy of the era is evidenced by several industrial sites labeled as Coal Mines (inactive) and a lone Coal Mine (inactive) further north. These inactive excavations suggest a cycle of extraction that had already passed its peak by the time of the survey. The land is otherwise sparsely marked, with drainage features like Richardson Coulee and Otter Creek providing the primary landmarks alongside a solitary Windmill on the open range.
