The Clovis culture
Mammoth hunters with fluted spear points

In 1929 stone points were found among the bones of Columbian mammoths near Clovis, New Mexico. The Clovis culture spread across North America for just three centuries, about 13,050–12,750 years ago, and for decades it was thought to be the continent's first, until older sites turned up.
