Ice circle

An ice disc, ice circle, or ice pan is a natural phenomenon that occurs 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. Ice discs have most frequently been observed in Scandinavia and North America, but they are occasionally recorded as far south as England and Wales. An ice disc was observed in Wales in December 2008 and another was reported in England in January 2009.

Ice circles vary in size but have been reported to be more than 4 metres (13 ft) in diameter.


Formed by natural processes.. ceated by eddies in the water and friction.
