The Devil’s Kettle is a notable geological feature located at Judge C.R. Magney State Park in Minnesota, USA.
The mystery begins with the Brule River, which splits around a large rock formation. One half continues over a natural waterfall, falling to the ground below. The other half plunges into a deep pothole, known as the “kettle.” For decades, the water that vanished into this kettle seemed to disappear without a trace, baffling scientists and researchers. Attempts to track the water—by throwing logs, ping-pong balls, and other objects into the hole—never yielded a resurfacing point in Lake Superior or the downstream portion of the river.
The Solution
The mystery was finally solved in 2017 by hydrologists from the Minnesota Department of Natural Resources (DNR) using scientific measurements.
The solution was achieved by precisely measuring the volume of water flowing in the river:
Above the falls (upstream).
Below the falls (downstream).
The measurements revealed that the upstream and downstream volumes were nearly identical.
This crucial finding confirmed that the water entering the Devil’s Kettle does not leave the river system. Instead, it must rejoin the river underground a short distance after its dramatic disappearance. The water is simply flowing through a natural, subterranean passage.
