About this map

The confluence of the Little Snake River and the Yampa River serves as the central focal point of this Moffat County landscape. At Lily Park, these two significant waterways meet before the Yampa winds westward into the protected canyons of Dinosaur National Monument. The terrain is defined by dramatic elevation shifts, moving from the river valley floors up to the expansive plateau of Twelvemile Mesa and the prominent heights of Cross Mtn.

Transportation through this high-desert environment is facilitated by the Yampa Valley Trl and Deerlodge Road, which track the river's path toward the deep incisions of Cross Mountain Canyon. Numerous drainage features like Graham Gulch, Sawmill Canyon, and Buffalo Gulch illustrate the complex erosion patterns that have shaped this portion of the Colorado Plateau. This map captures the intersection of public land conservation and the ranching geography of the western slope.
