Petit Fort Porter County

Petit Fort was a structure located in northwestern Indiana, in or near the Indiana Dunes, near the mouth of Fort Creek, now known as Dunes Creek. It may have been a French military outpost, but was more likely a private residence, trading post, or at most a support station for larger forts in the area. The National Park Service refers to it as a "fur depot."
