Jebels Awenat and Arkenu, Libya

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. Thousands of years ago, rainfall was more plentiful, and the Jebels were occupied by people, as attested by the numerous rock drawings. The images were acquired July 19, 2012, and July 31, 2013, cover an area of 66 by 67 kilometers, and are located at 22.1 degrees north, 24.8 degrees east. https://photojournal.jpl.nasa.gov/catalog/PIA22283
