This is a fun history trip if you are into that sort of stuff. You can also see a bunch of other interesting things if you are willing to travel some. Like preserved parts of the Organon trail etched into rock by wagon wheels, independence rock which is a main marker on the journey that if you don't reach by the right time you might.. you know, die. If you find yourself in the area and it is summer-ish this is worth checking out. Just plan ahead. There are closures, maybe specific requirements to request a tour, etc...

Upon becoming established, it was influential in shaping the western part of America. It was the best-known and largest fort on the Northern Plains until 1890, when it was abandoned. Known as 'The Embassy on the Plains,' trappers, traders, Native Americans, soldiers, missionaries, miners, ranchers, homesteaders, and anyone traveling west on one of the historic trails passed through here to trade or pick up supplies to continue their journey.
