Brrrrr! Lots of snow in this Space Shuttle photograph! It shows an area about 240 miles across. You are looking southeast across part of Quebec, and you can see the deep blue of the Saint Lawrence Seaway in the background. It leads to the Great Lakes off the right edge of the image. Can you see any craters? Image Courtesy of NASA/Johnson Space Center. Space shuttle photograph STS51B-43 060.
