Foragers (2,000 - 9,000 years ago)
By 9,000 years ago the last Ice Age had ended and the climatic patterns somewhat characteristic of the modern period became established. Many of the animals such as mammoths, camels, horses, and others that had dominated the Plains during the Ice Age were extinct. People changed the way they lived in response to shifts in climate and available plants and animals. More diverse hunting was practiced, utilizing both large and small game species. Wild plant resources were also exploited to a greater extent than during the Paleoindian tradition. People continued a nomadic lifestyle. Permanent villages are unknown, although the same location may have been returned to from year to year. Many changes in tool forms appear. No longer are particular projectile point styles found over large areas. It appears that the range or movement of people was more localized than during the Paleoindian period.
