Polar vortex: Lake Michigan turns to sea of giant ice balls
The polar vortex which has plunged the US into sub zero temperatures has caused yet another incredible sight - huge boulders of ice in Lake Michigan
The sub zero temperatures have brought huge, nuclear snowballs to the shores of Lake Michigan.
The incredible basketball sized - and bigger - 'ice balls' have been captured on film at Glen Arbor Township, Michigan, were they cover the entire shoreline.
Despite appearing as unnatural creations, the boulders are a regular feature of Lake Michigan when temperatures drop below freezing, and are formed by ice clumping together in a similar way to snowballs.
Meteorologist Joe Charlevoix explains: "[When] the water temperature on the Lake Michigan is just a little bit below freezing, so you get a small piece of ice that forms in the water and as waves move back and forth it adds additional water and freezes in layers.
"It gets bigger and bigger, and eventually you get big balls of ice, that are pushed to the shore by the wind."
Some locals have an alternative explanation however: "The creature that dwells within Lake Michigan lays eggs once every 10,000 (or so) years. Evacuate now while you still can!" joked Les Lukacs on the Glen Arbor Facebook page.
