2017 Map of Threemile Butte

About this map

Thunder Basin National Grassland dominates the northern reaches of this high-plains landscape, where the Cheyenne River cuts a winding path across the arid terrain. The map details a network of dry drainages and family-named landmarks that define the ranching heritage of Niobrara County. Distinctive landforms like Threemile Butte and Sheldon Hill serve as orientation points amidst a series of named draws, including Whitney Draw and Rock Corral Draw. Water management in this open range is highlighted by the New Deal Number 1 Reservoir along Boggy Cr, a name reflecting the historical necessity of capturing seasonal runoff. Primitive roads such as Zerbst Rd and Dutch Joe Rd link these remote outposts, following the natural contours of the basin floor toward Hungry Hollow in the southeast.
