Jebel Uweinat is a mountain range in the area of the Egyptian-Libyan-Sudanese border. The mountain lies about 40 km S-SE of Jabal Arkanu. The main spring called Ain Dua lies at the foot of the mountain, on the Libyan side. The W foot is 618 m high, and overcast with giant boulders fallen because of erosion. In general, the W slope constitutes an oasis, with wells, bushes and grass. The area is notable for its prehistoric petroglyphs first reported by the Egyptian explorer Ahmed Pasha Hassanein--the discoverer of Uweinat, who in 1923 traversed the first 40 km of the mountain towards E, without reaching the end.
