2017 Map of Prospect Mountains

About this map

Continental Divide crests the high terrain of the Prospect Mountains in this high-altitude Wyoming landscape. The map records a complex network of historic transit corridors, including the Lander Pinedale Stage Rd and the Lander Cutoff Rd, which highlight the region's significance for overland travel and early western migration routes. These thoroughfares cross a drainage system defined by Mitchell Slough, Little Mitchell Slough, and the headwaters of Little Sandy Cr. In the lower elevations, Rollins Bottom and Alkali Draw indicate the more arid, flat reaches of the basin below the peaks. Prospect Reservoir serves as a critical water feature in a landscape dominated by seasonal creeks and sloughs, providing a clear reference point for the hydraulic management and ranching history of Sublette County.
