The Teton, moving westward from their early habitat to the east and north of the Minnesota, were encountered on the banks of the Missouri by Captains Lewis and Clark when they ascended the river, during the early autumn of 1804. On September 26 of that year the expedition reached the mouth of Teton River (the present Bad River), which enters the Missouri from the west at Pierre, Stanley County, South Dakota. Here stood the great village of the Teton, concerning which Sergeant Gass gave a very interesting account in his journal: "We remained here all day. Capt. Lewis, myself and some of the men, went over to the Indian camp. Their lodges are about eighty in number, and contain about ten persons each; the greater part women and children. The women were employed in dressing buffaloe skins, for clothing for themselves and for covering their lodges. They are the most friendly people I ever saw; but will pilfer if they have an opportunity. They are also very dirty: the water they make use of, is carried in the paunches of the animals they kill, just as they are emptied, without being cleaned.... About 3 o'clock we went aboard the boat accompanied with the old chief and his little son. In the evening captain Clarke and some of the men went over, and the Indians made preparations for a dance. At dark it commenced. Captain Lewis, myself and some of our party went up to see them perform. Their band of music, or orchestra, was composed of about twelve persons beating on a buffalo hide, and shaking small bags that made a rattling noise. They had a large fire in the centre of their camp; on one side the women, about 80 in number, formed a solid column round the fire, with sticks in their hands, and the scalps of the Mahas they had killed, tied on them. They kept moving, or jumping round the fire, rising and falling on both feet at once; keeping a continual noise, singing and yelling. In this manner they continued till 1 o'clock at night, when we returned to the boat with two of the chiefs." (Gass, (1), pp. 45-46.)
