Missouri River [SEP] First people
Indigenous peoples of North America who have lived along the Missouri have historically had access to ample food, water, and shelter. Many migratory animals naturally inhabit the plains area. Before they were hunted by colonists and Native Americans, these animals, such as the buffalo, provided meat, clothing, and other everyday items; there were also great riparian areas in the river's floodplain that provided habitat for herbs and other staple foods. No written records from the tribes and peoples of the pre-European contact period exist because they did not yet use writing. According to the writings of early colonists, some of the major tribes along the Missouri River included the Otoe, Missouria, Omaha, Ponca, Brulé, Lakota, Arikara, Hidatsa, Mandan, Assiniboine, Gros Ventres and Blackfeet.
