The Naco Mammoth Kill Site is an archaeological site in southeast Arizona, 1 mile northwest of Naco in Cochise County. 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 (eroded by the Greenbush Creek, a tributary of the San Pedro river), while digging out the fossil bones of a mammoth. Emil Haury excavated the Naco mammoth site in April 1952.Haury, Emil W., "Artifacts with Mammoth Remains, Naco, Arizona : Discovery of the Naco Mammoth and the Associated Projectile Points", American Antiquity 19, pp. 1–14, 1953ERNST ANTE, "Artifacts with Mammoth Remains, Naco, Arizona : Age of the Clovis Fluted Points with the Naco Mammoth", American Antiquity 19, pp. 15–18, 1953JOHN F. LANCE, "Artifacts with Mammoth Remains, Naco, Arizona : Description of the Naco Mammoth", American Antiquity 19, pp. 19–24, 1953 In only five days, Haury recovered the remains of a Columbian Mammoth in association with 8 Clovis points (including the 2 originally found by the Navarettes). The excavator believed the assemblage to date from about 10,000 years Before Present. An additional point was found in the arroyo upstream.Haury, Emil W., "The Naco Mammoth", Kiva, vol. 18, no. 3/4, pp. 1–19, 1952Naco Mammoth Kill Site - The Southeast Archeological Center - National Park Service The Naco site was the first Clovis mammoth kill association to be identified in Arizona.

In 2020, small charcoal fragments were found adhered to a mammoth bone from the site. AMS radiocarbon dating produced a mean date of 10,985 ± 56 years Before Present.Huckell, Bruce B., et al., "The Naco Clovis Site: Old Excavations and New Dates", PaleoAmerica, vol. 8, iss. 3, pp. 1-13, 2022 https://doi.org/10.1080/20555563.2022.2058903
