Devil’s Kettle is a mysterious natural structure. It is located on the North Shore of Lake Superior, in Minnesota. The Brule River flows through Minnesota’s Judge C. R. Magney State Park, and then it gets split in two waterfalls. The east half falls down normally 50 feet and continues toward the lake. However, the west half disappears in a very large pothole and is never seen again. Until today, no one knows where that water disappears.
