About this map

Cretaceous Mtn dominates the high-desert landscape of Sublette County in this 2015 study, surrounded by a complex system of dry washes and essential water sources. The importance of groundwater in this arid environment is evident through several named points of interest, including Mountain Home Spring, Tip Top Spring, and DeGraw Spring. These features supported the early ranching and transit networks of western Wyoming, where access to water dictated the routes of travel and settlement.

Logistics across this terrain are defined by the Big Piney Calpet Rd and several Bureau of Land Management routes, such as BLM 5328 RD, which navigate around deep geological cuts like Deloney Canyon and Black Canyon. This topographic record provides a clear look at the drainage patterns of Dry Piney Cr and its various forks, showing how the land was carved into features like Little Mesa and Dry Basin Draw.
