The Devil's Kettle is located in Judge C. R. Magney State Park along the north shore of Lake Superior. The falls along the Brule River has geological interest because it splits into two, half of it going over a 50 foot waterfalls and flowing into Lake Superior. The other half disappears into a pot hole. The outlet of this part of the river has never been discovered. Because the flow of the pothole is conducted away laterally, there is no satisfactory explanation for how it was formed.
yes, that is what is seems to do. There is a theory that there is a fault line that the water runs through on its way to the lake, but it is only a theory, somehow, from what I can understand is seems to run away to the side, rather than down. But perhaps I have misread. There is some good information about it on line if you have a desire to read about it.
