The Mystery of Devil's Kettle Falls

November 24 2015


We're going to explore the mystery of Devil's Kettle Falls in Northern Minnesota. Located along Lake Superior's North Shore, the falls have been puzzling hikers and geologists for years. No one knows where the water is going. We're going to send in an OpenROV, and see if we can find out. Current Status: Preparing for November 2016 Trip Read background

Preparation Stage

"What happened with this expedition?"

A number of people have asked me that recently. Quick answer: we missed the weather window last year.

But we're still going! The goal now is to take one of the new OpenROV Tridents later this fall. It will be more robust and better able to deal with the conditions. Also, much easier to hike with.

Expedition Background

Eric Stackpole always tells me:

"If the job is Dirty, Dangerous, Dull or Distant, then it's better to send a robot."

This expedition, searching for an answer to the mystery of Devil's Kettle Falls, is of the dangerous - and maybe just flat out impossible - variety. The picture and video explain more than I could write. Basically, no one knows where the water is going on the second waterfall. Not hikers. Not geologists. No one has been able to figure this out.

We're going to send in an OpenROV. Because it's back-packable (and relatively inexpensive), we're going to hike in and drop the robot down the second hole. We'll see how far we can explore and where all of this water is going.

The plan is to do this in November, but is very weather dependent. It may have to wait until next summer. Also, it's pending approval from the authorities.


Awesome guys! Following! Have fun before the snow gets there.

Very cool! I was just there this summer; impossible not to wonder what's down there. Good luck!

Very exciting! Many cavers in the Northeast were just talking about Devil's Kettle. Though some have been in many difficult and dangerous caves, this one is too dangerous for a person. OpenRov might be able to finally solve the mystery that's fascinated many for so long.. I can't wait to see what you find! Good Luck!

I was so excited to hear about this expedition! Whatever happened with it?
