Leaving behind a collection of extensive drawings and a detailed journal, two company clerks provided great insight during the reconstruction of Fort Union Trading Post. Located on the Upper Missouri River and the Montana / North Dakota border, the Fort Union Trading Post dates to 1828. This important trading post of the time lasted for 39 years. Its life span was long before the Plains Wars and saw a peaceful coexistence between Plains Indians and white traders.
      The full scale replica fort takes in more than an acre, dwarfed by the wide open prairie. The 18 foot high, whitewashed palisade walls are set off by two defensive bastions (towers). Inside, the main Bourgeois house is today's visitor center. The replica is built on the same footprint as the original. Details include a bell tower, large flagpole, ice house, blacksmith shop and massive gates. The fort is operated by the National Parks Service and open to the public.
