This video of a giant spinning ice-disk is beautiful and hypnotic

Drone footage shows this beautiful ice disk floating in a river in Maine, USA. Intrigued by this phenomenon we naturally consulted Wikipedia which informs us:

“Ice discs, ice circles, ice pans, or ice crepes are natural phenomena that occur in slow moving water in cold climates.

Ice circles are thin and circular slabs of ice that rotate slowly in the water. It is believed that they form in eddy currents. It has been shown that existing ice discs can maintain their rotation due to melting.

An unusual natural phenomenon, ice disks occur in slow moving water in cold climates and can vary in size, with circles more than 15 metres (49 ft) in diameter observed.”

And here it is!

And here it is from another angle.
