The coarse terrain of the Tanezrouft Basin earn it an ominous nickname : Land of Terror . A rough wilderness of stone and shifting dunes always blast by inexorable wind , this is a land of furrowed stunner and geology laid bare .
Long ago , water eroded the canyons , river basin , and plateau of this basin in the Algerian Sahara . Now , steer extend to blast and glossiness exposed aqueous stone , uncover homocentric loops bands like sand highlights the beauty of woods grain . Steep canyon walls loom 250 to 500 meters above the surroundings , while dunes migrate across the landed estate .
This image is of the radio detection and ranging reflectivity as observe by the European Space Agency ’s Envisat satellite . The rougher a surface is , the brighter it is so that faults are brilliantly white , while soft , sanded rock are darker . The image is a composite taken in three pass on March 23 , 2009 , June 1 , 2009 and September 14 2009 , capture the dynamical landscape painting as basics is gnaw into deposit , and deposit deposit into shifting sand dune . The coloring ponder modification between each radiolocation pass .
