Utah’s Ancient Mega-Landslides: Geology, Discovery, and Guide to Earth’s Largest Terrestrial Landslides (C-132)

by Robert F. Biek, Peter D. Rowley, and David B. Hacker

Southwest Utah contains what may be the largest landslide complex on land in the world. This complex includes three ancient side-by-side gigantic slides that cover an area roughly the size of Yellowstone National Park with a volume of slide debris that would nearly fill the Grand Canyon to its rim. This guide tells the history of their discovery, describes many of their unique and unusual features, and offers over a dozen places visitors can go to see the rocks that tell this fascinating story.
