About this map

Purdy Reservoir and the Steffensen Number 2 Reservoir anchor this high-plains landscape in Johnson County, where the intricate drainage system of the Crazy Woman Creek dominates the topography. The map illustrates a complex network of water management and natural runoff, featuring the N Fork Crazy Woman Cr, Middle Fork Crazy Woman Cr, and S Fork Crazy Woman Cr. These waterways are supplemented by man-made infrastructure like the Devoe-Ditch Number 1, reflecting the region's reliance on water rights and irrigation.

Local landmarks often bear the names of early ranching families and settlers, such as George Hess Draw and O'Malley Draw. The terrain is further defined by the T A Hills and various seasonal channels like Billy Cr and Poison Cr. While Interstate 25 provides modern transit, older routes like Robinson Canyon Rd and Middle Fork Rd trace the traditional paths through the draws and canyons of this Wyoming ranching country.
