In Westbrook formed a 90-metre perfectly round ice that doesn't melt

Strange, very evenly rotating ice circles in rivers are extremely rare in nature. Scientists call the ice floe in Westbrook, which is estimated at 90 m giant, because of such phenomena like size never found.

Ice formation is on the river for several days, while more generally there is no ice. The circle rotates counterclockwise, and it is often sitting ducks, the newspaper notes.

Scientists are trying to study the ice disks from the XIX century, but the process stops very rare appearance of such a phenomenon. Probably, it is connected with the river current, which in the center becomes a whirlpool. It does not allow the ice to move down the river and allows it to increase in size.

In addition, the upper part of the ice melts and turns into water — the difference in water temperature around the disk also causes it to gradually accelerate.
