Rare polar blue ice has come to the shores of the Great Lakes - and it's stunning photographers

Things are looking blue this week in Michigan.

On Sunday, people near The Mackinac Bridge - which straddles Lake Michigan to the West and Lake Huron to the East - noticed huge blue hunks of frozen lake water coming ashore.

I's a rare sight to see this kind of brightly colored ice in the state. Blue ice is usually seen in permanently chilly spots like Antarctica and the North Pole, as well as on other slippery glaciers around the world.

As a result, some photographers were downright giddy to share their photos with Business Insider.

Take a look.
