Giant rotating ice disk draws attention, visitors

WESTBROOK, Maine (AP) — Think of it as a crop circle, but in a river.

A curious formation that’s getting attention in Greater Portland is actually a spinning ice disk that is roughly 91 metres wide.

The formation in the Presumpscot River was widely shared on social media and has drawn comparisons to an alien spacecraft, a carousel and the moon.

The oddity drew a crowd that stood mesmerised by the slow-turning disk on Tuesday afternoon in Westbrook.

The ice formation is believed to have formed naturally in a part of the river where there’s a circular current that creates a whirlpool effect, said the city’s Marketing and Communications Manager Tina Radel.

Locals said they’ve seen smaller ice disks before, but nothing like this one, Radel said. Rob Mitchell, who owns a nearby office building, spotted the alien-looking disk on Monday morning and immediately notified the city.

Officials said the disk is spinning slowly counter-clockwise, and has served as a big raft for ducks and other birds.

“The ducks were rotating on this big Lazy Susan,” Mitchell said.
