Freaky, huge ice disk discovered spinning in North Dakota river

[knocker]

 

There it was, just sitting in the Sheyenne River — a perfect circle of ice, about 50 feet in diameter, gently rotating in the water.

 

George Loegering's discovery of the huge ice disk last Saturday has been a big hit over the Web after his video of the phenomenon went viral.

 

"It's an amazing wonder," Loegering, 73, of Casselton, N.D., said in the video, which was reproduced by the Associated Press. "I don't have a clue how it did it, but that thing is rotating, as you can see."

Although hardly commonplace there are many examples of all sizes, I am surprised quite such a fuss has been made about this one!

Hardly a fuss when the article said this.

 

 

Similar phenomena have been documented in colder states and countries. You can see videos of somewhat similar disks here, here and here.

You get these occasionally though thats quite an impressive example. One happened on my local river in 2009: http://www.telegraph.co.uk/earth/4227030/Spinning-ice-disc-phenomenon-seen-in-British-river-for-first-time.html said to be the first time ones been recorded on England but I doubt it.

 

Then in December 2010 I saw a similar formation myself on the same river less than 100m from my house.. although it had sort of frozen back into the surrounding ice:

Poor reporting, there aren't many countries colder in winter than North Dakota, never mind states in the US.

Bar Alaska, I think ND is the coldest state, narrowly edging Minnesota?
