1951 Map of Cedar Butte NW

About this map

Pine Ridge Indian Reservation lands dominate this western South Dakota landscape, where the Reservation Boundary follows the divide between Washabaugh Co and Mellette Co. The terrain is defined by a dense network of drainages including Black Pipe Creek, Cottonwood Creek, and Porcupine Creek, which cut through the open country of Prospect and Cedar Butte. Human settlement is sparse and tied to the water and grazing potential of the plains, most notably at the Walker Ranch in the north.
