DescriptionFort Union Trading Post National Historic Site, reached via US 2 and SR 1804, is 25 miles southwest of Williston, N.D., and 24 miles northeast of Sidney, Mont. Founded by John Jacob Astor for his American Fur Co. in 1828, the trading post became the center for the fur trade on the Upper Missouri River. The fort was 1,800 miles by river from St. Louis, the nearest supply point.
Excavators unearthed the foundations of the Bourgeois House, palisades, bastions, a Native American trade house, an icehouse and other structures. The trade house has been rebuilt and furnished as it might have appeared in the early 1850s. The fort's walls and bastions also have been reconstructed. A visitor center in the reconstructed Bourgeois House features exhibits about the fort and the fur trade.
