A waterfall known as The Devil's Kettle empties water into a hole and nobody know where it ends up!

If you’ve ever worried that we’ve solved all the mysteries of nature, fear not. Minnesota’s Devil’s Kettle Falls has been puzzling hikers and geologists for generations. At the falls, along Lake Superior’s north shore, a river forks at a rock outcropping.

While one side tumbles down a two-step stone embankment and continues on like a normal waterfall, the other side vanishes into a deep hole and disappears apparently forever.

People have thrown dyes, logs and other things into it and have been unable to find out where all of this stuff along with the water goes. Are you brave enough to go there and try to find out where this pothole leads to?
