About this map

The Rattlesnake Hills dominate this portion of Natrona County, where the high desert landscape is defined by traditional western freighting routes and isolated water sources. The Waltman Sweetwater Freight Rd cuts through the basin, following a historic corridor for transportation across the drainage divides. Higher elevations are marked by landmarks like Black Mtn and the distinct formation of French Rocks near the eastern boundary.
