Clovis: Clovis is the name given to a prehistoric cultural manifestation found widely across North America and dating to the waning three centuries of the last glacial interval (ca. 11,200 to 10,900 radiocarbon years ago or RCYA; 12,900-12,550 calendar years ago). Ice still covered most of what is now Canada and lowered sea level expanded the coastal margins, especially along the Atlantic and Gulf of Mexico shorelines. Clovis sites are found from the southern margin of the continental ice sheets to Central America, from the Atlantic to the Pacific in virtually every kind of environment that existed at the time. Defining traits are large, fluted spearpoints (fig.1), a highly distinctive way of flaking large bifacial point preforms and knives, prismatic blades (fig.2), and pointed rods of bone or ivory. Clovis artifacts, especially points, are often found in association with bones of mammoths, but caches of stone tools and campsites with a variety of tools and debris are all characteristic.

Folsom: Folsom is the name given to the prehistoric culture that succeeded Clovis in the Plains, Prairies, and parts of the southwestern region of North America. Radiocarbon dates for this archaeological manifestation primarily fall within the interval of 10,900 to 10,200 BP. Folsom sites frequently consist of small, highly distinctive, fluted spearpoints found among the bones of bison (fig.3,4). Other characteristic stone tools are large and very thin knives and well-made hide scrapers. This was a specialized, nomadic bison hunting adaptation. [Folsom site references: Amick 1999; Boldurian and Cotter 1999; Wilmsen and Roberts 1978; Frison and Bradley 1980.]

Late Paleoindian: Following Folsom along the southern periphery of the Great Plains where the Gault site is located is a succession of regional archaeological cultures, each identified by a diagnostic style of projectile point. Dates for most of these style intervals are not well established, but as a group they fall within the interval of ca. 10,000 to 9,000 RCYA. Such names as Wilson, Golondrina/Barber, Angostura, and St. Marys Hall have been attached to the projectile points, but at present, not much is known about the lifeways of the people who left these materials behind [Collins 1995, 1998].
