The Hartley Mammoth Site is a pre-Clovis archaeological and paleontological site in New Mexico. Preserving the butchered remains of two Columbian mammoths, small mammals and fish, the site is notable due to its age (~37,500 BP), which is significantly older than the currently accepted dates for the settlement of the Americas.
