The nomadic tribes of the Great Plains survived on hunting, some of their major hunts centered on deer and buffalo. Some tribes are described as part of the 'Buffalo Culture' (sometimes called, for the American Bison). Although the Plains Indians hunted other animals, such as elk or antelope, bison was their primary game food source. Bison flesh, hide, and bones from Bison hunting provided the chief source of raw materials for items that Plains Indians made, including food, cups, decorations, crafting tools, knives, and clothing.
