For decades, geologists from all over the northland were perplexed by the kettle. Rumors ran rampant as people tried to figure out what was happening to all the water. Some claimed that it led to an underground cave, others said that it flowed through a lava tube down deeper in the earth. While these were logical guesses, the type of rock in Judge C.R Magney State Park does not coincide with underground caves or lava tubes.
The next most logical thing to do was throw things down the Devil’s Kettle to see where they come out. People threw everything down there from sticks and logs to ping pong balls. Allegedly, a group of people even threw a car into the kettle, but this seems highly unlikely due to both the size and the inaccessibility of the kettle itself. With everything being dropped into the mysterious funnel, nothing had ever been seen again.
In 2017, a Minnesota hydrologist named Jeff Green decided to find out what was happening once and for all. He and a group of his peers measured the amount of water going over the falls along with the amount of water near the base of the falls. With results being very similar, it was determined that the water flowing into the Devil’s Kettle was deposited right back into the Brule River somewhere near the falls.
