With all the bitter cold we’ve seen this winter throughout the region, it’s probably no surprise to learn that Lake Superior is reaching levels of ice coverage that haven’t been seen in 5 years.
A false-color satellite image of Lake Superior taken Tuesday shows ice and snow in light blue and open water in dark blue, and there’s very little dark blue to show.
There’s a little along the far western short, near Isle Royale, and just east of the Keweenaw Peninsula.
The rest, including the Apostle Islands, are pretty much locked in ice.
As of February 11, the lake is 88% frozen, which amounts to about 28,000 square miles of ice cover.
And the Great Lakes on the whole are a shade over 80% coverage, the most ice coverage since 1996.
