Image Caption: Most of the Great Lakes Region (45.0N, 84.0W) appears in this single photo as well as part of COLUMBIA's payload bay and spacelab module. In the center, Lake Michigan and Chicago are clearly visible. The absence of clouds over the lakes is because of different temperatures between the landmass and the lakes. The warming land surface causes air to rise and form clouds while the cold lake water retards cloud growth and remain cloud free.
