Chiquihuite Cave is a possible Upper Paleolithic archaeological site in the Astillero Mountains, Zacatecas State, in North-Central Mexico. Chiquihuite Cave may be evidence of early human presence in the Western Hemisphere up to 33,000 years ago. It is located 2,740 meters (9000 feet) above sea level and about 1 kilometer higher than the valley below. The lithic artifacts discovered here have been dated to 26,000 years ago based on more than 50 samples of animal bone and charcoal found in association with the tools. There is scholarly debate over whether the artifacts should be considered evidence of human activity or if they were formed naturally.
