Snowballs spending a day at the beach

"It happens when there's a heavy snowfall and some wind at a time when the water is cold enough to freeze but due to motion it is prevented from doing so.

Conditions must be: Water temperature at zero deg. C., snow falling into the waves and combining together as the waves roll it along; think of it rolling a snowball on a liquid surface rather than a field, I'm sure you get the idea.

In Cape Breton this phenomenon is known by local fishermen as "a Lolly".

From foamymilkyway, where there are additional photos of this phenomenon.
