The influence of large-scale bedrock landslides in carving Grand Canyon
Robertson J. The influence of large-scale bedrock landslides in carving Grand Canyon. Research Permit and Reporting System
The effects of large-scale landsliding on the continental-scale Colorado River system in Grand Canyon remain poorly understood. This paper describes deep-seated bedrock landslides in the Surprise Valley area by combining detailed mapping, volume balanced cross-sections, strath terrace heights, and cosmogenic burial dating of river deposits buried by landslides. Mapping shows failures involving ~1000 m Paleozoic section localized within basal shale detachments, dammed and diverted the Colorado.
