Ice Age Fossils in Clark County, NV

This 315-acre park features a portion of the upper Las Vegas wash that is rich in both paleontological and historical resources. During the Pleistocene, also known as the Ice Age, the wash provided verdant habitat for several species of now-extinct mammals, including Columbian mammoths, American lions, camels, dire wolves, and ground sloths. The discovery of abundant fossils onsite triggered a long history of scientific research, which includes the famous “Big Dig” of 1962-3, the largest interdisciplinary scientific expedition of its kind up to that point.
