Once serving as part of the floor for a much larger Lake Chad, the area now known as the Bodele Depression, located at the southern edge of the Sahara Desert in north central Africa, is slowly being transformed into a desert landscape. In the mid-1960s, Lake Chad was about the size of Lake Erie. But persistent drought conditions coupled with increased demand for freshwater for irrigation have reduced Lake Chad to about 5 percent of its former size. As the waters receded, the silts and sediments resting on the lakebed were left to dry in the scorching African sun. The small grains of the silty sand are easily swept up by the strong wind gusts that occasionally blow over the region. Once heaved aloft, the pastel-colored Bodele dust can be carried for hundreds or even thousands of kilometers.

The remnants of Lake Chad appear as the olive-green feature set amid the tan and light brown hues of the surrounding landscape where the countries of Chad, Niger, Nigeria, and Cameroon all share borders. The Bodele Depression was the source of some very impressive dust storms that have swept over West Africa and the Cape Verde Islands in recent days. This true-color Aqua MODIS image was acquired on February 11, 2004.

Looks beautiful from up here; probably just pretty gritty and draughty down there... Wouldn't want to get caught out in it, in any case http://www.tombraiderforums.com/images/smilies/privateeye.gif
