Williston, Williams County, North Dakota, 58801
At this post, the Assiniboine, Crow, Cree, Ojibway, Blackfeet, Hidatsa, and other tribes traded buffalo robes and other furs for trade goods such as beads, guns, blankets, knives, cookware, and cloth.
Between the fort gates through the south entrance is the Trade House. Historically when tribes came to trade, the main trading sessions were done here.
