Oneota

Oneota is a designation archaeologists use to refer to a cultural complex that existed in the eastern plains and Great Lakes area of what is now the United States from around AD 900 to around 1650 or 1700. The culture is believed to have transitioned into various Macro-Siouan cultures of the protohistoric and historic times such as Ioway. A long-accepted ancestry to the Ho-chunk has yet to be conclusively demonstrated.
