"Ice circles" are going viral! Danika Klock shares this one that she saw on the Musselshell River. Montana FWP says these ice discs "form on the outer bends in a 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 circle." | ABC FOX Montana
