1952 Map of Ervay Basin

About this map

Ervay Basin defines the central landscape of this mid-century survey, revealing a remote ranching and grazing district in central Wyoming. The settlement of Raderville stands as a focal point in the eastern portion, situated near the headwaters of the Powder River. The map documents a sparse human footprint centered around the JE Ranch and the nearby JE School, which likely served the families of the local basin during the early 1950s. The terrain is marked by significant topographical landmarks such as Maverick Butte and Cyclone Ridge, with essential water resources like Sulphur Spring and Defelder Reservoir noted. Industrial activity is represented by a small Quarry and a traversing Pipe Line, while the winding Poison Spider Rd provides primary access through the broken terrain of the Coalbank Hills.
