About this map

Industrial development in the late 1960s defines this corner of Sublette County, where an extensive network of oil wells and gas wells dots the high-elevation landscape. The terrain is dominated by the massive ridge of Cretaceous Mountain and the expansive Big Mesa, which rise above a series of drainages including Fogarty Canyon Creek and Beaver Creek. A dedicated Pumping Sta and a network of pipelines illustrate the infrastructure required to transport resources from the surrounding oil field toward larger hubs.

Scattered evidence of human settlement and ranching operations appear at Mountain Home Ranch and the locality of DeGraw near the North Fork Piney Creek. The hydrology of the area is marked by seasonal and permanent features like Tip Top Spring and a Gaging Sta, providing essential water data for the high plains ecosystem. Genealogists and local historians can trace the specific placement of early ranching outposts and extraction sites before modern intensification altered many of these original access points.
