Fort Union Trading Post National Historic Site

Fort Union was established in the early 1800s by the American Fur Company as the principal trading post on the upper Missouri. For roughly four decades it was the busiest fur post on the northern plains, where steamboats and keelboats brought trade goods up the river and carried bison robes and furs back down. It was a place of business first, and its success rested on relationships with the Native nations who supplied the trade.

Many tribes came to trade at Fort Union, among them the Assiniboine, the Crow, the Blackfeet, the Cree, the Ojibwe, and the Mandan, Hidatsa, and Arikara whose homeland lay downriver. At the post, Native and newcomer economies met, and goods, ideas, and people moved in both directions. The fort was also visited by artists and naturalists who left some of the earliest detailed records of the region and its peoples.

Life at Fort Union revolved around the trade room, where furs and robes were exchanged for cloth, metal tools, beads, and other manufactured goods. The post was a small, diverse community of company men, laborers, interpreters, and their families, many of them of mixed Native and European heritage, and diplomacy was as important as commerce in keeping the trade flowing peacefully.

The reconstructed fort recreates this world. Visitors can walk the white palisade walls, enter the well-appointed Bourgeois House where the trader in charge lived, and step into the trade room stocked with the goods of the era. Living-history programs and demonstrations bring the daily rhythms of the post to life during the warmer months.

The fur trade that sustained Fort Union eventually collapsed as bison herds dwindled, tastes changed, and the U.S. Army moved into the region. The old fort was dismantled in the mid-1800s, its materials used to build a nearby military post, and for more than a century only the archaeological traces remained.

In the twentieth century, the National Park Service studied the site and reconstructed the fort on its original footprint, guided by paintings, records, and excavation. The result is one of the most complete and evocative reconstructions of a fur-trade post anywhere, giving visitors a vivid sense of the crossroads that once stood here.

The fort sits on the north bank of the Missouri near its meeting with the Yellowstone, on open river bottom and prairie in the far northwest corner of North Dakota. The setting is broad and quiet, and a visit combines naturally with the nearby confluence area and its interpretive center just across the line.

Summer is the fullest season, with living-history programs, demonstrations, and the annual rendezvous drawing visitors, though the open prairie can be hot and windy, so sun protection helps. Fall is cooler and golden along the river, winter is cold and still, and spring greens the bottoms. Checking the program schedule ahead helps time a visit to the fort's liveliest days.
