Summary

DescriptionASTER Richat.jpg	English: Richat Structure, Oudane, Mauritania - This prominent circular feature in the Sahara desert of Mauritania has attracted attention since the earliest space missions because it forms a conspicuous bull's-eye in the otherwise rather featureless expanse of the desert. Described by some as looking like an outsized ammonite in the desert, the structure [which has a diameter of almost 50 kilometers (30 miles)] has become a landmark for shuttle crews. Initially interpreted as a meteorite impact structure because of its high degree of circularity, it is now thought to be merely a symmetrical uplift (circular anticline) that has been laid bare by erosion. Paleozoic quartzites form the resistant beds outlining the structure. The image was acquired October 7, 2000, covers an area of 45 x 47 km, and is located at 20.9 degrees north latitude and 11.6 degrees west longitude.
