Ice Circles

Reader Jodi DeMeulenaere submitted this photo of ice discs or circles floating on Coldwater Creek. She said she and her husband had never seen them before. They are one-and-a-half to two-and-a-half feet across.
No — these natural occurrences are not made by aliens. 
After a little research on Google, it turns out the phenomenon, which can be likened to frozen lily pads, can be solid enough for a person to stand on, not this size, but bigger ones that get as large as 50 feet in diameter. 
According to Wikipedia, the ice discs can 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. As it spins in the water, which is caused from it melting, it smooths it into a circle.
These circles are typically found in cold climates, such as North America and northern Europe.
Thanks for sending it in!
