On another note: I have recently received a number of inquiries regarding how one can donate to my blog. Everyone has been so generous with my daughter and grandson’s fund that I have hesitated to put a donation option back on my posts, but I have been encouraged to do so and it will return in January. Meanwhile, in response to those who have recently inquired about supporting my Naturally Curious blog with a donation, you can go to www.naturallycuriouswithmaryholland.wordpress.com and click on “Donate,” or send a check made out to me to 134 Densmore Hill Road, Windsor, VT 05089. Thank you so very much.

    Ice disk formed in an eddy

      I agree about disc formed from an eddy

  2. We have these ice discs form each winter at thr bottom of our dam. It is caused by small discs joining into a mass. As the mass spins in the stream’s current it’s edge is carved by more solid ice.

    A naturally-formed ice circle. First heard of these about a year ago, then saw a bunch of smaller ones in Stoddard NH later in the winter. A friend and I made an artificial “ice carousal” last January on Tolman Pond, hope to do it again this winter. Much fun.

      How did you do this?

    That’s a huge one…I’ve seen those ‘ice pancakes’ at the bottom of a water fall, on either side of a fish ladder….much smaller, though & lots of them….real fun to see.

    This phenomenon used to occur sporadically in my hometown (probably still does) and was even published in a Ripley’s Believe it or Not when my grandfather was mayor well over 60 years ago. The spinning disc of ice there was about 24′ in diameter

    Very interesting! First time I’ve seen one or heard about it. Nature continues to amaze!

    It is probably not where a UFO landed but possibly where the water eddies forming the circular ice patch.

    Looks as if river currents have created an annular “whirlpool” around what appears to be an island. As the inboard edge of the whirlpool freezes, it attracts and freezes more water, causing the circumference to increase exponentially.
    Or could it be an alien’s frozen frisbee?

    this looks like an eddy that captured pieces of ice.

    Where a round ice fisherman’s hut was?

    My husband and I saw one of these many years ago. Somehow in a back Eddie a circle starts to form and goes around and around and around. It was beautiful. Like a potters wheel. It is being shaped by the rotation. Incredible.

    We saw these near Peterborough, ON, last December. Here’s the observer’s hypothesis: http://www.drewmonkman.com/sightings/mystery-circles-in-ice-on-pond-at-clear-lake/

    Northern Woodlands Dec. 8 e-newsletter reported on an occurrence of an ice disk in the Adirondacks. It references the Physical Review E Journal, which said “conditions must be very precise in order for these circles to form” and that they “occur as a result of changing temperatures.” Or, you could say it’s magic.

    This is an eddy ice disk, formed by a naturally occurring eddy in the river in which the water circulates continuously behind an obstruction in the current and the surface slowly freezes, causing the ice disk to form

    Ice forming in an eddy.

    December 18, 2017 at 10:46 am

  16. I like the Ice Disk idea but I would go out on a limb and speculate that the water was frozen, and two ski mobils crossed over , doing 360’s while at it; then you had melting. At the center of the picture are what looks like two washboard marks, so that’s my wild 2cent guess. 🎅❄️

  17. Josie

    I believe it is called an ice circle or ice disc.

    December 18, 2017 at 10:53 am

  18. The ice disc in an eddy is just too far fetched. I’m certain it’s a spot where a round intergalactic UFO with a super-efficient reverse heat pump hovered over the water and expelled frigid air downward as exhaust.

    An otter dragged a trap onto the ice, where the chain got stuck, and then ran in circles until something broke free and it escaped?

    December 18, 2017 at 10:59 am

  20. Barry Avery

    Quite obviously an a Alien space ship landing site. It could be an underwater Spring too.

    Looks like someone had fun on a snowmobile, a bit too close to open water in my opinion!

    There was a recent article explaining this very amazing thing.

  23. I wanted to say this was a beaver lodge frozen in, but my husband guessed it was the result of water currents freezing in this shape. Looks like he was right. Darn!

    December 18, 2017 at 12:05 pm

  24. It’s one of Mother Nature’s works of art!

    December 18, 2017 at 12:09 pm

  25. Treah Pichette

    Looks like a crop circle! 😉

    December 18, 2017 at 1:29 pm

  26. Doug Sherry

    I think it has to do with the wire overhead. Maybe snow or ice dropping off and hitting the ice such that water under the ice ripples out and freezes, creating the circle.

  27. Joan waltermire

    Did a long chunk of ice fall into a thin coat of ice on the water and…you’ve got me beyond that! Ain’t nature grand.

    December 18, 2017 at 2:12 pm

  28. Thea Lahti

    An eddy that has formed around a log or rock, and then frozen. The eddy current must have been moving more slowly than the stream’s current.

    December 18, 2017 at 2:39 pm

  29. KT

    Hmm, my guess would be some sort of eddying or differential current rates causing rotational shear in the ice. My other guess would be otters on ice skates. 🙂

    December 18, 2017 at 4:29 pm

  30. Dan Allen

    This looks like an ice island rotated about some sort of subsurface center (rock or stump) close to the water surface . It is turned and ground round by the passing ice floes.

    An eddy at the edge of a stream can form a circle like this.

    December 18, 2017 at 5:18 pm

  32. Kathy Schillemat

    That is a huge ice pancake! We have seen similar much smaller ones at the bottom of a spillway and waterfall in Stoddard, NH. Interesting stuff. I don’t know how this one got so big!

    December 18, 2017 at 7:56 pm

  33. VDOT’s engineers have too much time in winter. Designing
    River Roundabouts seems like a waste of time. But Mother Nature has shown us not to disturb such beauty! Please NO salt!!! This a true river traffic calming devise. Ahhhhhh amazing!

    December 19, 2017 at 6:36 am

  34. Russ Patton

    I think the circular pattern is formed in the river by eddies. The movement of water does not allow the ice to form as one smooth piece.

    Ice circle ,usually on a bend in the river where there are strong currents.

    A round tuit, definitely!

    December 19, 2017 at 3:30 pm

  37. cdhd2017

    A beaver swimming around his den could make this ice pattern around his home.

    How do we send you some pictures of an animal prowling around Lyme that has lots of people “naturally curious “?
