English: A relatively rare blanket of ice rested on the surface of Lake Superior in early March 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image of the lake and its surroundings on March 3, 2009. In this true-color, photo-like image, ice floating on the surface of Lake Superior ranges in color from white to pale gray-blue. The ice appears most solid along the southern shore of the western half of the lake. North of that solid band of ice, cracks reveal deep blue lake water. Dark lake water also appears in the eastern part of the lake, especially along its northern shore. As it does in the west, ice cover appears relatively unbroken at the extreme southeast end of the lake.
