The Clovis culture was first discovered on the 29th of August 1929 when Ridgely Whiteman found stone tools near Blackwater Draw in New Mexico. This site became the type site for the culture and was named after the nearby town of Clovis.
The Clovis point is a distinctively shaped bifacial stone projectile point that is typically fluted with an elongate flake removed from the base. It was made using percussion flaking for initial preparation and pressure flaking for finishing, often requiring years of practice to produce without breaking.
The Clovis people were high-technology foragers who hunted big game including Columbian mammoths, mastodons, bison, and equines. Isotope analysis of the Anzick-1 burial suggests mammoths made up a large proportion of their diet with major contributions from elk and bison.
The Clovis people originated from Siberia and migrated into North America, with the culture spanning from 13,050 to 12,750 years Before Present. Genetic evidence from the Anzick-1 infant confirms their Asian origin and connection to Siberian populations.
The Clovis culture ended around 12,750 to 12,600 years Before Present due to megafauna decline and decreasing mobility. It was succeeded by regional cultures including the Folsom tradition, Cumberland point, Suwannee point, and Western Stemmed Tradition.
