The Naco Mammoth Kill Site is an archaeological site in southeast Arizona, near Naco, Arizona. The site was reported to the Arizona State Museum in September 1951 by Marc Navarrete, a local resident, after his father found two Clovis points in Greenbush Draw, while digging out the fossil bones of a mammoth. Emil Haury excavated the Naco mammoth site in April 1952. In only five days, Haury recovered the remains of a Columbian Mammoth that had been killed by the use of at least 8 Clovis points about 10,000 years ago. The Naco site was the first Clovis mammoth kill association to be identified.
