... 2 m.y. We document a sequence of eight landslides. Three are Toreva-block landslides containing back-rotated but only mildly disrupted bedrock stratigraphy. The largest of these landslides, Surprise Valley landslide, is hypothesized to have dammed the Colorado River, cut off a meander loop through...

...Eric R. Meyer; Ron A. Harris ABSTRACT Structural and geomorphic studies, and lithostratigraphic and biostratigraphic mapping reveal that a giant toreva block (6.125 km 3 ) slid off Mount Timpanogos toward what are now densely populated urban areas along the Wasatch Front of Utah. The block forms...
