About this map

The Cheyenne River Indian Reservation dominates the northern landscape of this mid-century survey, where the winding Cheyenne River carves through a series of high tablelands. This 1956 field study documents the area just as the Missouri River Basin development program was beginning to reshape the region; the map explicitly notes areas designated to be submerged by the impending Oahe Reservoir.

The settlement pattern is defined by isolated family operations such as Vanderveer Ranch, Sunshine Ranch, and the Schiesser Ranch in the south. For genealogists and local historians, the sheet preserves the locations of Walking Horse Cem and Lindsay Cem along the river breaks. Distinctive topographical features like Marion Flats and Rich Flats illustrate the transition from river bottomlands to the sprawling ranching plateaus that characterized Stanley and Dewey counties during this era.
