Frozen Solid As anyone who's lived around the Great Lakes knows, this winter's been very cold. To confirm the obvious Nasa has published these remarkable images showing the ice cover in 3 of the 5 Great Lakes (Can you name them all, in order of increasing size?). Take a look at the detailed image to really see the ice cover. It's interesting that the western side of the frozen lakes show a bit of water that's ice free. I wonder if that's due to prevailing winds from the West?
