Half of this waterfall disappears into a hole never to be seen again.
So where does the water go? So far, nobody knows — but not for lack of trying. Scientists and hikers will keep tossing things into the Devil’s Kettle and watching Lake Superior for any sign of their trinkets, but maybe there are other explanations. If you happen to be traveling, say, somewhere in Eurasia and stumble across a geyser that’s surrounded by pingpong balls, logs, and even a car that locals are reported to have pushed in one night years ago, you might want to call a geologist in Minnesota. You may just have solved the mystery of Devil’s Kettle Falls.
