These large snowballs have been washing up on the shores of Nyda, in the Yamal Penninsula of eastern Russia. Some of them are as big as three feet in diameter! The locals say they've never seen anything like it.
They result from a rare environmental process where small pieces of ice form, are rolled by wind and water, and end up as giant snowballs.
Russians are having fun with the phenomena. One commenter predicted they would hatch into "snowsaurs." See more pictures of the snowballs at BBC News. -via Boing Boing
