About this map

The Continental Divide winds through this high desert region of Sweetwater County, marking the hydrological crest between the Atlantic and Pacific watersheds. This 1980s landscape is defined by its arid drainage systems, including the long paths of Deadman Wash, Potash Wash, and Ninemile Wash that cut through the undulating terrain. To the north, the distinctive Black Rock formation and Spring Butte overlook Randor Springs, providing rare water sources in a dry expanse.

Industrial activity is evident in the eastern half of the map, where a Strip Mine and various prospects indicate the extractive economy of the late 20th century. While most of the area remains open rangeland, the presence of The Meadows in the southern section suggests a pocket of moisture or lower-lying grazing ground. The survey captures a moment when traditional resource extraction and geologically significant landmarks coexist on the Wyoming high plains.
