A large cluster of walled Mandan, Hidatsa and Arikara villages situated on bluffs and islands of the river was home to thousands, and later served as a market and trading post used by early French and British explorers and fur traders.
Un gran grupo de poboados con estacadas dos mandan, hidatsa e arikara situábanse sobre os acantilados e illas do río e foron o fogar de miles de persoas, e máis tarde serviron como mercados e postos comerciais utilizados polos primeiros exploradores e comerciantes de peles franceses e británicos.
