2021 Map of Separation Canyon

About this map

The Colorado River cuts a deep path through northwestern Arizona, defining the boundary where the Grand Canyon National Park meets the Lake Mead National Recreation Area. This terrain is characterized by massive elevation shifts between the high Sanup Plateau to the north and the Hualapai Plateau to the south. Within the Lower Granite Gorge, the river is marked by a series of significant whitewater features, including Two Hundred and Forty-one Mile Rapids and the well-known Separation Rapids. The landscape is etched by deep side drainages such as Separation Canyon, Gneiss Canyon, and Bridge Canyon, providing a detailed look at the canyon's complex geological structure. For those tracing the river's path on foot, the Colorado River Trl follows the water's edge through some of the most isolated stretches of the gorge.
