SUMMARY: This is a satellite photograph of two huge sandy regions in the Fezzan region of Southwest Libya, near the border of Algeria.

The photograph was taken by the European Space Agency's Envisat satellite using its Medium Resolution Imaging Spectrometer (MERIS).

The image going with the story is interesting. The round feature in the image seems to called a dry lake bed in the story, but I can't help wondering if it is an old impact basin filled with sand. Do any of the geologists on the forum know how to tell?

I agree - it looks like a crater. None shown on tis map, though ...
