The 218-Mile Toreva Block


The 218-Mile Landslide is a classic example of a Toreva block.  Although many of the landslides in Grand Canyon and Colorado Plateau exhibit rotational movement, only a few are as intact as the Toreva block shown in the photo below.


 This view above 220-Mile Camp in the western Grand Canyon shows a textbook example of a Toreva-Block landslide high above the Lower Granite Gorge on river right.  As with other large landslides in Grand Canyon, this one experienced basal failure in the Bright Angel Shale.
