COLOSSAL, NATURALLY FORMED ICE CIRCLE APPEARS IN A WASHINGTON RIVER
Photographer captures image of phenomenal spinning ice disk.
Ice circles are a fairly unusual but completely natural phenomenon which is known to occur in North America and certain areas of northern European, especially the wintery Scandinavian countries of Finland, Denmark, Sweden, and Norway. The discs are formed in incredible cold whether when slow moving rivers begin to freeze over. A large piece of ice breaks off owing to pressure from the river current. A process then occurs which is known as a ‘rotational shear’. What this means is that the slow moving current of the river gently erodes the jagged corners of the ice away at an incredibly slow pace. At the conclusion of the process, the free floating shard of ice is smoothed into a perfect circle. The ice circle then begins to settle and spin with the current of the river. Messer was certainly lucky to be able to catch a glimpse of this unusual and wonderful natural phenomenon first hand, and thanks to her incredible photographic skills the rest of the world can share her experience with her.SOURCE
