Clovis Culture, Clovis is the oldest clearly defined culture known in North America, with radiocarbon dates concentrating in the range of 11,200–10,900 years BP (before the present) (though a few sites have yielded dates three to four centuries older). Its most characteristic artifact, the Clovis projectile point is lanceolate (axially elongate with roughly parallel sides curving to a point), with a concave base, and one or more elongate axial flakes removed from each side of the base, presumably to facilitate hafting to a shaft.
