Kiyuska
Kiyuska is placed on the eastern Great Plains, where the James River of the Dakota country runs through wide valleys of grass and tall prairie. Indigenous peoples of the region combined cultivation along the river bottoms with hunting bison on the open plains and travelling through varied landscapes. Dakota (Sioux) bands camped along the rivers, while Hidatsa and Mandan villages stood farther up the Missouri. In the late eighteenth century Ioway and Dakota groups moved through the eastern plains, trading furs and horses with French and British traders from the Red River and the Upper Missouri.
