1951 Map of Smithwick NE

About this map

The Cheyenne River cuts across the northwest corner of this 1951 survey, defining the lower reaches of the Black Hills foothills. This landscape is characterized by its prominent upland plateaus and deep drainage systems, most notably the Squaw-Humper Table and the extensive Pine Ridge Indian Reservation Boundary along the eastern edge. Settlement is sparse, focused around the small community of Smithwick in the southwest, while the remainder of the territory is a network of named canyons and flats. Local topography is deeply etched by watercourses such as Jim Wilson Canyon and First Black Canyon, which drain the elevated benches of Harrison Flat and Wagon Flat. The map reflects a mid-century period of land management and Missouri River Basin development, captured just as aerial photography began to provide precise detail of these complex South Dakota landforms.
