About this map

The Colorado River carves a deep, winding path through this corner of Grand County, Utah, defined by a series of named whitewater challenges including Skull Rapids, Funnel Falls, and Sock-It-To-Me Rapids. The river course is flanked by dramatic elevation shifts through Westwater Canyon and Star Canyon, creating a landscape dominated by high plateaus and drainage systems. To the south, the prominent geological formations of Big Triangle and Little Triangle rise above the confluence of seasonal watercourses like Coach Creek and Ryan Creek.

Evidence of modern recreation and movement through the high desert is found on Buckhorn Mesa and along the Mel's Loop Tr, while the presence of Cane Spring and Sand Flat highlights the traditional survival points in an arid environment. The map details a complex network of dry washes and canyons, such as Agate Wash and Cow Canyon, which illustrate the erosional patterns typical of the Colorado Plateau.
