The Laurentian Great Lakes

Carved by ice during the last glacial period, the Laurentian Great Lakes do not yet exhibit any ice cover on November 4, 2020 in this composite of Aqua/MODIS data. Lake Erie and Lake St. Clair (the "Sixth Great Lake") are shallower and more eutrophic than the other lakes, and they appear brighter because of the higher suspended sediment loads in their waters.
