The disk drew fans from around the globe when it first appeared in the river in 2019. It also partially formed in 2020.
Ice disks can form because of a current and vortex under ice. The ice sheets spin and form into circles. Officials with Westbrook have cautioned against attempting to go out on the ice disk.
