Widespread late Palaeoindian tradition in North America from 10,000-7000 BP. In the west, it is characterized by bison hunting and diverse projectile point styles; complexes include Agate Basin, Hell Gap, Cody, and Frederick. The characteristic unfluted leaf-shaped projectile point appears to have developed from Llano and Folsom types. These many styles or types have been identified by such local names as Plainview, Angostura, Milnesand, Agate Basin, and Scottsbluff and their primarily hunting culture may be included in the term Plano. The Plano complex or culture type was a direct descendant from the fluted-blade early American hunters. As the climate moderated, peoples of the Late Plano complex moved north into Saskatchewan and Alberta with the grazing game animals and, by 3000 BC, had reached the Arctic tundra zone in the Northwest Territories of Canada. It is the most recent of the three major Palaeoindian cultures.
