This Sea-viewing Wide Field-of-view Sensor (SeaWiFS) true-color image of Lake Michigan shows
a lake effect where clear dry air moves eastward
from Wisconsin, picking up moisture as it traverses the lake and forming dense clouds by the time it reaches Lake Michigan's eastern shore. The scene was acquired on January 17, 2002.
Note the newly-fallen snow that covers Wisconsin, Michigan, and northern Illinois. The southern edge of the snow line extends to just south of the Chicago area. Chicago sits on the southwestern shore of Lake Michigan.
Except for cloudy areas in the west and east and around Lake Superior, the entire Canadian portion of the broader image can be seen to be snow covered as well. Lake Winnipeg (upper left) and James Bay (upper right of center) are frozen over.

The light tan oval in this image is the floor of a lake in central Italy that has been drained by a tunnel dug through the surrounding hills. Numerous rectangular fields occupy the former lake bottom—now one of the most fertile regions of Italy. The area is still referred to as “Fucine Lake,” even though the lake has been dry for nearly 150 years.
