WESTBROOK, Maine (AP) City officials say Maine’s famous giant spinning ice disk may soon meet its end, due to unseasonably warm temperatures.

The Portland Press Herald reports the disk in the Presumpscot River has lost most of its shape and its appearance that made it look like a blue moon.

Westbrook spokeswoman Tina Radel says the disk was on the move Wednesday, but it’s “time may be limited.”

The ice disk formed in early January, drawing crowds to the river’s edge and attracting attention on social media.

It is believed to have formed naturally where there’s a circular current that creates a whirlpool effect.

Radel says a webcam set up by scientists from Brown University that provides time-lapse photography of the disk will remain in operation through the spring.
