These Mysterious Ice Pancakes Have Taken Over a Scottish River

Weird things happen in the winter cold. At the River Dee in Scotland, that includes dozens of recently discovered "ice pancakes" floating on the river surface. Their strange shapes boggle the imagination, but rest assured, there's an explanation for their existence.


The River Dee Trust, which first posted the photos online, suggests eddies in the river are likely responsible for the ice's shape. As freezing foam swirled in the eddies, they formed into little disks. And all that jostling around on top of the river creates the raised edges. The pancakes may have grown over several days, with freeze-thaw cycles each day and night accounting for the tree-like rings.

These ice pancakes have also been found in Antarctica and in the Great Lakes, when the conditions are just right. (The video below shows ice pancakes jostling in a Great Lakes tributary.) Ted Scambos, a lead scientist at the National Snow and Ice Data Center told National Geographic, however, that it's rare to see ice pancakes solid enough to be picked up. More often, they're just delicate slush gently floating on the surface.

And neat and neat and neat and neat! Earth science just getting me all excited this morning (also, coffee, lots of coffee). Cannot wait till Littleswimming is older so we can dork out together! (or she can run and hide from her Mom, whatever.)
