A catastrophic landslide that rivals in size the largest known gravity slide on the surface of the Earth has been mapped in southwestern Utah by geologists. The Markagunt gravity slide, the size of three Ohio counties, covered at least 1,300 square miles and its full scope is still being mapped. It could prove to be larger than the Heart Mountain slide, the largest known on the Earth's surface.
