About this map

The Green River carves a dramatic path through the heart of Dinosaur National Monument, defining the central character of this northeastern Utah landscape. The river's powerful descent through Split Mountain Canyon is marked by a series of significant whitewater features, including Moonshine Rapids, Schoolboy Rapids, and Inglesby Rapids. This corridor served as a vital, if treacherous, artery for early explorers and settlers in Uintah County.

Evidence of early ranching life persists at the Josie Ranch and along the nearby Chew Ranch Rd, indicating the hardscrabble livestock operations that once thrived near the Yampa Plateau. Topographic landmarks such as Split Mountain and Mitten Canyon rise sharply above the water, while the Ruple Point Trail offers access to the high overlooks of Ruple Point. The presence of Little Rainbow Park and Docs Valley provides a glimpse into the isolated basins used for grazing and transit between the canyon walls.
