Ice disk

I've previously posted photos of interesting ice formations, including round ice floes in Russia and a "creek circle" in Canada.  This photo above was posted at the cosmos of enlightened vision; the disk was reportedly seen on the Salmon River in Idaho.

  1. Cool! When I was a kid I used to see these every once in a while in the brook that ran behind our house. We'd watch them for a while, then break them up by chucking rocks at them from the bank and watch the chunks bump away downstream. Good times!

  2. The Salmon River (and the Lewiston Morning Tribune) are both located in Idaho.

  4. Interesting, I remember reading an article some time ago that was about a similar phenomonon, which occured with a perfectly circular hole in the middle of ice, usually unstable to walk. It kinda tried to link it to crop cirlces somehow...

  5. Wow, this is a first for me, but my engineering training mentioned vector curl and so I see this as a natural example.
