NASA Photo ID: STS066-94-020       File Name: 20177638.jpg
  Film Type: 70mm                    Date Taken: 11/14/94
  Title: Lake Chad, Chad as seen from STS-66
  This oblique view of Lake Chad was taken by the STS-66 crew in November
  1994. This lake lies mainly in the Republic of Chad and partly in Nigeria,
  Cameroon and Niger. The size of Lake Chad varies seasonally and is actually
  divided into north and south basins; neither of which is generally more
  than 25 feet (7.6 meters) deep. In this photograph, all the water appears
  to be located in the southern basin with the northern and eastern edges of
  both basins covered with sand dunes which have invaded the area where the
  water once stood. The prevailing wind direction can be seen from the
  agriculture burning in both basins to be from the east.
