A swirling disc of ice on a river in the US state of Maine is drawing onlookers in the heart of winter once again.
The disc has formed in the Presumpscot River in Westbrook.
A handful of dog walkers and onlookers stopped to gaze at the curious ice formation on a chilly Thursday morning around dawn.
It also partially formed in 2020.
Ice discs can form because of a current and vortex under ice.
The ice sheets spin and form into circles.
Officials in Westbrook have cautioned against attempting to go out on the ice disc.
