2017 Map of Cretaceous Mountain

About this map

Cretaceous Mtn rises above a high-altitude landscape defined by its numerous perennial water sources and deep drainage systems. The terrain is marked by a network of springs, including Mountain Home Spring, DeGraw Spring, and Tin Top Spring, which feed into local water bodies like Dry Piney Cr and Sawmill Cr. This network of water sources was historically vital for livestock and early ranching efforts in this corner of Sublette County. The map also delineates several significant geologic features, such as Little Mesa and the branching systems of Deloney Canyon and Fogarty Canyon. Transportation through this complex topography is facilitated by established routes like Big Piney Calpet Rd and Black Canyon Rd, which connect the isolated canyons and draws across the plateau.
