The Mountain Uwaynat on the border of Egypt, Libya, Sudan
Jebel Uweinat (1,934 m; جبل العوينات gabal al-ʿuwaināt “mountain of sourcelets”; also spelled Jabal, Djebel Al Awaynat, Auenat, Ouenat, Ouinat, Owainat, Oweinat, Uwaynat, Uweinat, Uwenat, Uweynat etc.) is a mountain range in the area of the Egyptian-Libyan-Sudanese border. The mountain lies about 40 km S-SE of Jabal Arkanu.[1] The main spring called Ain Dua lies at the foot of the mountain, on the Libyan side. The W foot (located at 
21°52′29″N 24°54′16″E / 21.87472°N 24.90444°E / 21.87472; 24.90444 according to Hassanein)[1] is 618 m high, and overcast with giant boulders fallen because of erosion. [1] In general, the W slope constitutes an oasis, with wells, bushes and grass. [1] 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. [1] . Engraved in Sandstone, petroglyphs of Bushmen style are visible, representing lions, giraffes, ostrichs, gazelles, cows and little human figures. [2]
