On December 13th, 2008, This mysterious 'ice circle' appeared in, Mississauga, Ontario, Canada. They occur at bends in the river where the accelerating water creates a force called 'rotational shear,' which breaks off a chunk of ice and twists it around. As the disc rotates, it grinds against surrounding ice - smoothing into a perfect circle.

Hi Gerard,
Never heard, or seen anything like it. Wondering how rare a rotational shear is, or if its been captured on film before?
