The Grandest Fort on the Upper Missouri

Fort Union Trading Post was the most important fur trading post on the upper Missouri from 1828 to 1867. 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.
