Tule Springs Archaeological Site in Nevada’s Las Vegas Valley became a major archaeological locality after the 1933 Tule Springs Expedition led by Fenley Hunter. An unworked obsidian flake found near extinct Pleistocene animal remains drew attention to the area, and later investigations by the Nevada State Museum in 1962 and 1963, directed by Richard Shutler with sediment studies by Vance Haynes, confirmed evidence of Ice Age animals and early North American Paleo-Indian peoples. Discoveries included mammoths, ground sloths, prehistoric horses, American camels, and Nevada’s first recorded giant condors. Although claims that humans lived alongside and hunted extinct megafauna are no longer generally accepted, Tule Springs remains important for understanding southern Nevada’s late Pleistocene environment and deep history.
