2017 Map of Rattlesnake Lake SW

About this map

The Cheyenne River winds through the heart of this West River landscape, defining the jagged boundary between Ziebach and Haakon Counties. The terrain transitions from the broad, level expanse of Milesville Flat in the south to the intricately eroded breaks and draws of the river valley. Landmarks like White Thunder Bottom and the convergence of Straighthead Cr with the main channel reveal a landscape shaped by hydrology and cattle ranching. A sparse network of section-line roads, including Hardingrove Rd and 217th Ave, provides access to the remote uplands and draws. The presence of BIA Hwy 8 in the north indicates proximity to tribal lands, while named features such as Red Bull Draw and Black Bull Draw underscore the region's enduring ranching identity.
