Dakota Indians. The earliest known home of this tribe was on and near the Mississippi in southern Minnesota, northwestern Wisconsin, and neighboring parts of Iowa. In 1825, after they had spread somewhat farther west, Long (1791) gives their boundaries thus: They were bounded by a curved line extending east of north from Prairie du Chien on the Mississippi, so as to include all the eastern tributaries of the Mississippi, to the first branch of Chippewa River; thence by a line running west of north to Spirit Lake; thence westwardly to Crow Wing River, Minn., and up that stream to its head; thence westwardly to Red River and down that stream to Pembina; thence southwestwardly to the eastern bank of the Missouri near the Mandan villages; thence down the Missouri to a point probably not far from Soldiers River; thence east of north to Prairie du Chien. At a later time they occupied less territory toward the east but extended much farther westward between the Yellowstone and Platte Rivers.
Cheyenne Indians. This tribe moved frequently; in South Dakota they were associated with the Cheyenne River and the Black Hills. (See also Colorado, Kansas, Minnesota, Montana, Nebraska, North Dakota, Oklahoma, and Wyoming.)
Northern Shoshoni Indians. The Northern Shoshoni occupied eastern Idaho, except the territory held by the Bannock; western Wyoming; and north-eastern Utah.
