2021 Map of Twentyone Divide
USGS Topo · Published 2021About this map
The Cheyenne River winds through this High Plains landscape, marking a significant hydrologic feature where Wyoming meets South Dakota. This 2021 survey illustrates the intersection of several remote jurisdictional boundaries, including the line between Niobrara County, Wyoming, and both Custer and Fall River Counties in South Dakota. The eastern portion of the map is defined by large tracts of protected land, notably the Buffalo Gap National Grassland and the southern reaches of the Black Hills National Forest.
