(Video link here.) Photographer Kaylyn Messer made this wondrous, tiny video of an ice circle on the Snoqualmie River near Seattle. It’s a huge disk of ice formed when a large ice chunk breaks off in the river. In an effect called a rotational shear, the current slowly spins and grinds the ice into a perfect circle. It’s a divine little meditation: you hear the sound of the river and watch the circle slowly spin. Here are two 20-second views.
