File this under “Things That Make You Go Hmmmm…”:
A giant disk of ice, 100 yards wide, that formed by itself this week is swirling counterclockwise in the Presumpscot River here in Maine (not far from the Farmers’ Almanac HQ).
Is it aliens?
Birds are enjoying it—reports say they are hitching a ride on the icy merry-go-round and simply “hanging out.”
So why is it there, and how did it form? Scientists aren’t quite sure (ice disks like this one have been forming for centuries) but they’re investigating. One theory speculates that as the ice melts, it cools the warm water below, which creates an unseen vortex that spins the ice floe above. Slowly moving river water is believed to help get it started moving.
What do you think?
