Ancient underwater landslide deposit near Mono Lake, Mono County, California

Underwater landslide deposits exposed in the Mono Lake Basin (Mono County). The landslide deposit is sandwiched between normal flat-lying lake sediments. The deposits formed when the surface of Mono Lake was perhaps several hundred feet higher during one of the ice ages of the Pleistocene Epoch (roughly between 11,000 and 2 million years ago). The underwater landslide may have been initiated by strong earthquake.
