Fort Benton [MT]
Fort Benton is located on the banks of the Missouri River and served as a fur trading outpost. The fort was abandoned in the 1860s, and was occupied briefly by the U.S. military before it was finally abandoned for good in 1871. The fort has recently undergone an extensive renovation, and now serves as a museum of Montana history.
The fort offers exhibits, guided tours, and special events. The website offers visitor information and brief history of the fort.
