This image, released Saturday by NASA, shows Jebel Uweinat, a mountain range in the area of the Egyptian-Sudanese-Libyan border. The area is notable for its prehistoric petroglyphs. Engraved in sandstone, petroglyphs of the Bushman style are visible, representing giraffes, lions, ostriches, gazelles and human figures. The western part of the mountain consists of granite, arranged in a ring shape of some 16 miles in diameter, and its eastern part consists of sandstone. Four plateaus emerge from the level of the surrounding desert. One of the driest places on Earth, it reportedly hasn’t rained in this area since 1998.
