Ice balls in Lake Michigan
I don't know if these form by the same process as that which produced the "snowballs at the beach" that I posted yesterday. It could be, as someone has suggested, that the ones in the video (and perhaps the ones yesterday as well) are simply ice fragments from the lake ground into spherical shape by wave action.
