Fort Clark State Historic Site

Fort Clark Trading Post State Historic Site is one of the most important archeological sites in the state because of its well-preserved record of the fur trade and of personal tragedy. More than 150 years ago, it was the scene of devastating smallpox and cholera epidemics that decimated most of the inhabitants of a Mandan and later an Arikara village. The archaeological remains of the large earthlodge village, cemetery, and two fur trade posts (Fort Clark Trading Post and Primeau's Post) are protected at the site, located one and one-quarter mile west of the town of Fort Clark, Mercer County.
