The mountain 
The Jebel Uweinat (1,934m - 6,345ft) in Arabic: جبل العوينات (literally "mountain of springs"), also spelled Al Awaynat, Auenat, Ouenat, Ouinat, Owainat, Oweinat Uweinat, Uweinat Uwenat, Uweynat is a mountain in border between Egypt, Libya and Sudan. The Jebel Uweinat is located in the eastern Sahara, forty kilometers south-southeast of like mountains, the Jebel Arkanu, Libya.
The main source of solid, called Ain Dua, lies on its western foothills. This side is a cliff 600 meters high around which the foot is covered with large rocks fell under the effect of erosion. It is home to oases covered with bushes and herbaceous plants. A total of three valleys are oriented towards the West: Karkur Hamid Idriss and Karkur Karkur Ibrahim. To the East, the massif ends in the valley of Karkur Talh. The climax of the massif in its eastern half, is at the top of the Italia plateau.
The western half of the massif is an intrusion of granite forming concentric rings, the largest of which is 25 kilometers in diameter. The eastern half consists of sandstones forming four distinct trays.
The massif is officially discovered in 1923 by Ahmed Hassanein who, during his exploration, reports the existence of petroglyphs representing lions, giraffes, ostriches, gazelles or even oxen, in a style reminiscent of that of the Bushmen. He tries to cross the massif from west to east but makes a U-turn after traveling forty kilometers without finding an exit.
In the 1930s, each built a cairn at the top of the highest point of the massif.
