1951 Map of Twentyone Divide

USGS Topo · Published 1976

About this map

The Cheyenne River winds through this high-plains landscape where the borders of Wyoming and South Dakota meet. Surveyed in the early 1950s, the map reveals a sparsely settled ranching territory defined by the prominent Twentyone Divide and the deep incision of Twentyone Draw. The Black Hills Meridian serves as a critical surveying spine, separating Niobrara County from the South Dakota counties of Custer and Fall River.
