About this map

Dinosaur National Monument encompasses the heart of this landscape, where the Green River carves a dramatic path through the geologic uplift of Split Mtn. The river’s descent is marked by a series of white-water challenges including Moonshine Rapids, Schoolboy Rapids, and Inglesby Rapids, as it snakes through Split Mountain Canyon. Historical habitation is evidenced by the presence of the Josie Morris Cabin, located near the southern reaches of the monument boundary.

The topography is defined by significant structural features like the Island Park Fault and the high elevation of the Yampa Plateau. Drainage patterns are visible across various draws and canyons, from Horse Trail Canyon to Bourdette Draw. Access to this remote river corridor is limited to primitive routes such as Blue Mountain Rd and Docs Valley Rd, reflecting the preserved nature of the park's wilderness areas.
