1971 Map of Pamplin Hills

About this map

The Pamplin Hills stretch across this region of the Standing Rock Indian Reservation in Sioux County, North Dakota. This 1971 survey illustrates a land largely defined by its natural topography rather than dense urban development, showing the complex drainage patterns and elevation changes across the Pamplin upland. The map documents the Missouri River Basin’s development through its detailed rendering of the township and range system, specifically marking T. 131 N., T. 130 N., and T. 129 N.. Researchers will find a landscape marked by scattered seasonal ponds and a network of unimproved roads that navigate the varying terrain of the reservation during the early 1970s.
