50 Foot Spinning Ice Disc In North Dakota River

"It's not an unknown phenomenon, but it is relatively rare," said Loegering, who lives in rural Casselton, about 20 miles west of Fargo.

Allen Schlag, a National Weather Service hydrologist in Bismarck, and Greg Gust, a weather service meteorologist in Grand Forks, said a combination of cold, dense air last weekend and an eddy in the river likely caused the disk.

"It's actually quite beautiful," Schlag said.

Wow -



Ever seen or heard of one of these?

Ever seen or heard of one of these?

here's a few
I think one was posted here last year or maybe it was on the news.
Cool.

From Wikipedia:

"Ice discs form on the outer bends in a river where the accelerating water creates a force called 'rotational shear', which breaks off a chunk of ice and twists it around.[5] As the disc rotates, it grinds against surrounding ice — smoothing into a circle." For more info: en.wikipedia.org...

Several more of these on YouTube as well:

Amherst Massachusetts


Quebec Canada


Stowe Vermont

Nice everyone. Gonna love me some spinning ice disks.

Now all that's needed is a few ducks and geese on the merry-go-round.

Maybe its where a UFO hovered to suck up water?

Maybe you could replace that disk with something solid with gear teeth, turn a reduction gear and generator?

It may just be loose ice moving with the river current. there is probably a small under current, and you can see the main current is going around the edge causing the loose ice to spin. I'm no scientist, but that's what it looks like.

doubtful it can be mechanized and resourceful. But cool none the less.

Thats pretty cool but its just a natural occurrence

Amazing!
Both of the strange phenomena and the fact that the videographer didn't use one crude word!
But then, he is old and has had years to build his vocabulary.

Skaters are always spinning on ice, why can't ice spin on water. I'll give it an 8.5

I saw a programme on TV last year about this and a scientist was able to recreate this in a massive laboratory and took a few attempts but was able to show how it is formed. No mystery at all. Just one of those things out there that are not too common but can be explained easily. Don't know what the programme was called but a google search would probably find it...

Very cool topic, and no this has nothing to do with UFO's.

If you've ever been white water rafting or kayaking the rapids, you know how crazy and extreme under currents can be.

That being said, it's not all that uncommon to find these.

Extremely cool to see a forum up about this, SnF~

It's just an eddy of water, frozen on top. Simple.
