Megalandslides of The Colorado Plateau


Aerial oblique view of a series of retrogresive Toreva Block landslides along the Vermilion Cliffs near House Rock, AZ.  Toreva blocks are large rotational slump blocks exhibiting back rotation.   The term was coined by Dr. Perry Reiche of the U.S. Soil Conservation Service when he documented the bedrock landslides surrounding the Second Hopi Mesa near Toreva, AZ in 1937.  Toreva Blocks occur throughout the Colorado Plateau.
