Giant ice disk reappeared in the Maine River

One of the cities of Maine in the USA is celebrating the return of a massive ice disk floating on the river, after three years ago this wonderful winter phenomenon made a real splash. 

Tourists and media from all over the world came to the city of Westbrook in 2019, when a huge rotating ice circle appeared on the Presumpscot River. The amazing sight with a diameter of 300 feet was popular for several weeks, and then melted away and remained only a memory.

So it was until the beginning of this week, when residents noticed familiar shapes on the river. On Tuesday, it became clear that the ice disk, which one of the local TV channels proudly called "world famous", had returned. Unlike its predecessor, which appeared in 2019, this formation is still frozen in place, although, presumably, in the future it may begin to rotate if it breaks away from the frozen shore. The immobility of the disk did not weaken the enthusiasm for this phenomenon, as it has already begun to attract enthusiastic viewers.

Despite its otherworldly appearance, this is a natural phenomenon that occurs when a piece of ice rotates under the influence of water flow, and in the process its sides become smooth from friction against the shore.
