Rotating ice disc forms in U.S. river

A massive, spinning disk of ice that formed on a ME river has captivated both visitors and locals alike after video and images taken by a drone were shared by the city of Westbrook.

On nearly the exact same date Westbrook's natural ice disk was discovered, a group of people in Little Falls, Minnesota, made their own 506-foot-wide ice carousel.

The City of Westbrook released a drone's view of its insane ice circle.

Drone footage shows it nearly stretching across the whole of the Presumpscot River in Westbrook, Maine, US.

Locals had seen smaller ice discs before but nothing like this one, Ms Radel added. "I think it will continue to gain in thickness as long as it keeps spinning", said Mitchell, adding that the massive saucer acted as a giant Lazy Susan for ducks that made a decision to investigate it.

A curious formation that's getting attention in Greater Portland is actually a spinning ice disk that is roughly 100 yards (91 meters) wide.

"The Return of Wessie", she wrote of the ice disk.

The frozen water can be seen slowly rotating like a giant turntable. "It was a big duck-go-round".

The city also posted a drone video of the ice disk on its Facebook page.

Researchers believe ice discs spin because of temperature changes in the water, creating a vortex underneath.

California Institute of Technology physics professor Kenneth G. Libbrecht said the disk might be of a "world-record size, if anybody were keeping track", and stated most formations measure between 20 to 30ft in diameter, The New York Times reported.
