2015 Map of Split Rock

About this map

The Granite Mountains dominate this central Wyoming landscape where the Sweetwater River winds through high-altitude basin and range country. This area is defined by its massive geological formations, including the distinctive Split Rock landmark and the Great Stone Face. The map traces early water management efforts in this arid environment, marked by the Mcintosh Beaton Ditch and Speyers Reservoir. A network of creeks, such as Cottonwood Cr and Larkin Cr, flow from the higher elevations toward the river valley. The terrain is further characterized by prominent rises like Castle Rock, Henry Peak, and Cranmer Rock, alongside topographic features such as Telephone Line Ridge and the Beaton Pocket. This survey captures the rugged crossroads of Natrona, Carbon, and Fremont counties as it appeared in the early 21st century.
