1951 Map of Ridgeview NE

About this map

The Cheyenne River Indian Reservation encompasses this section of Dewey County, where the high plains are deeply incised by the drainage systems of the north. The Moreau River flows through the northern reaches of the quadrangle, carving a wide, undulating valley floor defined by intricate contour lines that reveal a complex system of bluffs and breaks. This landscape is a product of the Missouri River Basin development program, reflecting the topographic reality of the region in the early 1950s with later updates to road and infrastructure data.
