RIVERS — Photographer Gary Lane of Riggins, who does Salmon River rafting with Wapiti River Guides in Idaho, captured this image of a rare natural phenomenon that occurs in slow moving water in cold climates, such as January in the River of No Return Wilderness.

Ice circles are thin and circular slabs of ice that rotate slowly in the water. Generally they form in eddy currents. In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past an obstacle or disturbance to the flow, such as a bay.

Some mystics have seized on the “power” of ice circles.  Some wackos connect them with UFOs.
