Thousands of ice balls appeared on the shore of a lake in the United States

The administration of Holland Park in the state of Michigan (USA) shared photos of the shore of Lake Michigan filled with thousands of ice balls. This is reported on the official Facebook page of the Park.

CNN writes that the shore of Lake Michigan is strewn with ice floes ranging in size from baseballs to large yoga balls. According to the Park’s employees, they “had heard of their existence, but had never seen them before.”

USA Today adds: these ice balls form when the temperature drops slightly below zero. Ice balls are formed due to water flows that break the layer of coastal ice — its pieces connect and become rounded due to constant rotation around its axis.

A similar phenomenon was previously noticed in other parts of the world.
