Hueyatlaco
Puebla, Mexico
Hueyatlaco is an archeological site in the Valsequillo Basin near the city of Puebla, Mexico. After excavations in the 1960s, the site became notorious due to geochronologists' analyses, which have found wildly contradictory estimates for human habitation at Hueyatlaco dating from ca. 370,000 to 25,000 years before present (ybp). If correct, these controversial findings would substantially exceed the previous oldest-known evidence for habitation of the New World (the White Sands footprints dating to roughly 22, 000 ybp). The findings at Hueyatlaco are the subject of continued debate by the scientific community, and have seen only occasional discussion in the literature.
