Lake Superior ice blown around by wind

Two days ago, an East wind drove a lot of Lake Superior ice to our end of the Lake (above). Yesterday and today, we have had very high winds out of the west. Above, on March 6 we see the result of the East Wind, with a lot of ice in front of Duluth. After two days of West wind, a lot of that ice went back to the Lake. The Duluth harbor, connected to Lake Superior by the Duluth ship canal, followed the pattern, as you would expect. Two days ago, the harbor was full of ice, now it is full of blue water.
