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.
It’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.
It’s been a cold winter in Michigan, with sub-freezing temperatures and lots of snow. On Monday, the view from Mackinaw City, up at the top of Michigan’s lower peninsula, was quite a sight.
Blue-hued ice came towards the shores in jagged piles, inundating a local park where people trotted out to see the oddly colorful ice.
“The ice looks even better than photos can do justice,” Photographer Jeff Caverly told Business Insider in an email.
Blue ice isn’t any colder than normal ice. But it does have less air inside.
