History of Las Vegas Native Americans lived in the Las Vegas Valley, beginning over 10,000 years ago. Archaeologists have discovered baskets, petroglyphs, pictographs and other evidence in diverse locations, including Gypsum Cave and Tule Springs. Paiutes moved into the area as early as AD 700, migrating between nearby mountains in the summer and spending winter in the valley, near Big Springs.[1]
