These buffalo-hunting and horticultural people once dominated the vast open region of the Great Plains, west of the Mississippi River and east of the Rocky Mountains, that stretches from present-day Canada to Texas. The Native people of the Plains found this vast, harsh land rich in resources, with tall grass prairies abundant with herds of buffalo and other grazing animals and fertile river valleys that supported farming.
