2011 Map of Ringbolt Rapids

About this map

The Colorado River carves a path through the Black Canyon in this 2011 survey, marking the border between Arizona and Nevada. This stretch of river is defined by its turbulent waters, featuring a succession of natural hazards including Ringbolt Rapids, Cross Current Rapids, and Horseshoe Rapids. The desert landscape is punctuated by thermal features like Lost Man Hot Spring and Ringbolt Hot Spring, which suggest the geothermal activity present along the canyon floor. Notable landforms such as Liberty Bell Arch and the narrow passage of The Chute rise above the waterway, while the southern portion of the map shows the river widening into Lake Mohave. The presence of Cranes Nest Wash and White Rock Canyon illustrates the complex drainage systems that feed into the main river channel, providing a clear picture of the topography before these waters reach the dammed reservoirs downstream.
