Photographer Kaylyn Messer was browsing Facebook recently when she learned that there was a large ice circle in the river close to her home. She grabbed her camera, jumped into her car, found the circle, and shot a series of beautiful photos.
Ice circles are a fairly rare phenomenon that occur mostly in North America and Scandinavia in slow moving rivers during the winter. The discs are formed when a large piece of ice breaks off in the river creating an effect called ‘rotational shear’ where the current slowly grinds away at the free-floating chunk until its smoothed into a perfect circle.
Messer shares more photos and videos of the ice disc on her blog.
