#PPOD: In the far southeast corner of Libya, in the Libyan Desert, lie the uplifted massifs of Jebel Awenat and Jebel Arkenu. Both expose ancient Precambrian rocks, intruded by granites and then overlain with sandstones. Folding and doming have produced these interesting shapes, rising above the surrounding sand sea. Presently, the area receives less than one inch of rain per year. Credit: NASA/METI/AIST/Japan Space Systems, and U.S./Japan ASTER Science Team
