The Clovis culture was one of the earliest Native cultures in the United States about 13,500 to 12,800 years ago. The people of this culture consisted of Stone Age Paleoliths who moved in small groups and hunted mammoths with bony and flint-speared spears, among others.
The Clovis culture prevailed predominantly in what is now the United States, but some discoveries have even been made since Panama. The best known traces of this culture are the remains found in a cave near the town of Clovis, New Mexico, dating back 13,000 years. After only a few centuries of flourishing, the Clovis culture began its rapid division into numerous new local traditions across the continent and disappeared.
