How are Ice Circles are formed?

'Ice circles' are extremely rare natural phenomenon which occurs only in slow moving water at a particular speed and at a right temperature. Any variations in the above said variables will distort the formation and will lead to irregular or cracked Ice circles.

Ice circles are thin slabs of Ice which can rotate at slow speed and are formed by eddy currents. Every slab varies in size but they can reach more than 12 ft in diameter.
