1981 Map of Shirley Basin

About this map

Shirley Basin is defined by its massive high-altitude depression and the surrounding peaks of the Pedro Mountains, Seminoe Mountains, and Shirley Mountains. In the early 1980s, this landscape in Carbon County shows a complex water management system featuring the Pathfinder Reservoir and Seminoe Reservoir along the North Platte River. The presence of Mine Dumps and numerous Gravel Pits north of the eponymous Shirley Basin settlement highlights the region's mid-century industrial utility, which operated alongside conservation efforts like the Pathfinder National Wildlife Refuge.
