WESTBROOK, Maine (CBS) — It’s back! A massive ice disc that first appeared three years ago in a Maine river has returned.
“We can’t help but be excited for the return of the world famous Westbrook Ice Disk!” the city posted to Facebook. “Let’s enjoy it for as long as it’s here in our city.”
A nearby waterfall to the north creates churning water currents that help to form the disc. It can start to spin thanks to the current and temperature changes in the water underneath the ice that create a vortex.
