1960 Map of Separation Rim

About this map

The Separation Rim and its prominent Separation Point dominate this high-desert region of Wyoming, where the landscape is defined by massive geological escarpments and interior drainage basins. In the early 1960s, this area of Carbon County remained largely undeveloped, characterized by seasonal water features like Soda Lake and Bull Spring Lake that gather in the depressions of the Flats. Evidence of human activity is concentrated in specific industrial and ranching landmarks, such as the Strip Mine located in the northern sections and scattered infrastructure including a Corral and a long-distance Pipeline. The drainage patterns are clearly marked by Bulls Creek, Separation Creek, and Cold Spring Draw, illustrating the complex hydrology of the high plains before significant modern alteration. Further west, the Coyote Springs Rim forms another significant vertical break in the terrain, accessible only by a few unimproved tracks and the corridor of Route 287.
