2018 Map of Separation Canyon

About this map

The Colorado River cuts a deep path through the Lower Granite Gorge in this Mohave County landscape, where the waters are marked by a series of significant river features. Navigational challenges for river runners and historians are noted by the sequence of named white water, including Two Hundred and Fortyone Mile Rapids, the well-known Separation Rapids, and Gneiss Canyon Rapids. The terrain transitions from the high elevations of the Sanup Plateau in the north down into the canyons that define the border between Grand Canyon National Park and the Lake Mead National Recreation Area. Numerous deep drainages converge with the main river channel, most notably Separation Canyon and Bridge Canyon, providing a clear record of the complex geological drainage patterns in this corner of Arizona as they appeared in 2018.
