WESTBROOK, Maine - Think of it as a crop circle, but in a river. A curious formation that has grabbed the attention of Greater Portland, Maine, is actually a spinning ice disk, and it's roughly 100 yards wide.
The formation in the Presumpscot River has gone viral on social media, and it has drawn comparisons to an alien spacecraft, a carousel and the moon.
Rob Mitchell, who owns a nearby office building, spotted the alien-looking disk Monday morning and immediately notified the city of Westbrook, just outside Portland. Officials say the disk is spinning slowly counter-clockwise, and has served as a big raft for ducks and other birds. ducks.
"There were ducks sitting on it," Mitchell says. "The ducks were rotating on this big Lazy Susan. It was a big duck-go-round.''
