The Spirit Cave mummy is the oldest human mummy found in North America. It was discovered in 1940 in Spirit Cave, 13 miles (21 km) east of Fallon, Nevada, United States, by the husband-and-wife archaeological team of Sydney and Georgia Wheeler. He was said to be forty years old when he died. Analysis of the remains showed similarities to North and South American indigenous peoples and in 2016, the remains were repatriated to the Fallon Paiute-Shoshone Tribe of Nevada. The Spirit Cave mummy was one of the first to be dated using accelerated mass spectrometer radiocarbon dating. In turn, its discovery and analysis gave much insight and motivation of further research into the chronology of the western great basin.
