The Grand River in eastern Oklahoma, a south-flowing tributary of the Arkansas, drains a transitional zone—called the Prairie-Plains Peninsula—that separates the Ozark Highlands on the east and the Southern Plains on the west. This zone, about 50 miles wide, consists of scattered patches of open oak-hickory forest amidst mixed prairie and short-grass prairie habitats and occasional sandstone outcrops. In historic times, Osage Indians found the Prairie-Plains Peninsula a rich environment for hunting and small-scale agriculture. |
