Late Prehistoric Oneota population movement into the central Plains

The White Rock phase is an intrusive Late Prehistoric archaeological comple x in the central Plains. It shows clear ties to the Oneota tradition of the upper Midwest. Population movement best explains the presence of this Oneo ta complex in the Plains. Interpretations of seasonal mobility or migration are evaluated through analysis of White Rock phase assemblages. Evidence f or gardening and lithic material use patterns suggest permanent or year-rou nd occupation of the central Plains resulting from the Oneota migration.
