Earth from Space - Image Information

LOCATION Direction Photo #: ISS038-E-57977 Date: Feb. 2014
Geographic Region: USA-WISCONSIN

Snow-covered fields appear as geometric patterns on Lake Michigan's Washington Island in this photograph taken by the crew of the International Space Station. The island is 9 km long (5.6 miles) and lies on Lake Michigan's western shore, as a continuation of Wisconsin's Door Peninsula. (Note that north is to the lower left in the image.)

White coastal ice hugs the shoreline and connects Washington Island with Detroit Island and Rock Island. Ice typically accumulates first near land, where cooling is more rapid than in deeper lake water. Two other snow-covered islands (image top left) are small enough and far enough from land to evade the collars of ice.

On the day this image was taken, southwesterly winds were blowing ice into the lake in the form of long, coherent stringers. The thickness of a stringer is related to the length of coastline that feeds it. The smallest northern stringer (image left) is fed by the shortest section of upwind coastline, and the longest (image right) is supplied by the large amount of shore ice around Detroit Island. These dominant winds keep a narrow zone (along the western shore of the lake) clear of ice, even as accumulations in the winter of 2014 reach the highest levels ever recorded in Lake Michigan.
