1951 Map of Rockyford NW

About this map

The Pine Ridge Indian Reservation landscape is defined by the sharp transition between tablelands and river valleys in this 1951 study. High ground is dominated by Red Dog Table, which overlooks a complex network of drainages moving toward the southern and eastern edges of the quadrangle. The White River carves a significant path through the southeastern corner, supported by seasonal tributaries including East Horse Creek and Sand Creek. The map documents a sparse, open topography typical of the High Plains before modern infrastructure expansion, focusing on the natural drainage patterns and the distinct geological benches that characterize this part of Shannon County. This data was compiled as part of the Department of the Interior's Missouri River Basin development program, following aerial photography conducted in 1949.
