The Grandest Fort on the Upper Missouri River Between 1828 and 1867, Fort Union was the most important fur trade post on the Upper Missouri River. Here, the Assiniboine and six other Northern Plains Indian Tribes exchanged buffalo robes and smaller furs for goods from around the world, including cloth, guns, blankets, and beads. A bastion of peaceful coexistence, the post annually traded over 25,000 buffalo robes and $100,000 in merchandise.

Winter Hours: Site grounds with outdoor interpretive signs open year-round. Fort Buford State Historic Site preserves remnants of a vital frontier plains military post. Fort Buford was built in 1866 near the confluence of the Missouri and Yellowstone rivers, and became a major supply depot for military field operations. Original features still existing on the site include a stone powder magazine, the post cemetery site, and a large officers' quarters building which now houses a museum. Fort Buford, located near present-day Williston, was one of a number of military posts established to protect overland and river routes used by immigrants settling the West. While it served an essential role as the sentinel on the northern plains for twenty-nine years, it is probably best remembered as the place where the famous Hunkpapa Sioux leader, Sitting Bull, surrendered in 1881.
