North American Palaeo‐Indian cultures occupying the Great Plains and adjacent areas of the west and southwest, and extending east of the Mississippi into the Great Lakes area and across to New Jersey, during the period 9000–8000 bc. Believed to have developed from the Clovis Culture, Folsom is characterized by its fluted projectile points (generally rather smaller than Clovis points).
Most known Folsom Tradition sites are kill sites where bison have been slaughtered and butchered; some kill sites contain the remains of up to 50 beasts. A more substantial site at Hanson, Wyoming, has evidence of three hard‐standings which may have been the sites of houses. In addition to bison remains, bones of mountain sheep, deer, marmot, and cotton‐tail rabbit illustrate the diversity of species exploited by groups within this tradition.
