Fort Union Trading Post National Historic Site
Williston, North Dakota
We had already driven north to the Theodore Roosevelt National Park north unit entrance in North Dakota, and were only 60 miles away from this national historic site, so we made the trip on up to Williston.
What a neat experience it is to drive through the vast open prairie and see an old fur trading post appear.
According to NPS.gov, Fort Union was one of the most important and profitable fur trading posts on the Upper Missouri River between 1828 and 1867.
Several local Indian tribes exchanged large buffalo hides and smaller furs like beaver and rabbit, for a mixture of goods from all over the world.
