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.
