Chegga is an ancient fort and water-source in the north-east of Mauritania, close to the international border with Algeria, on an escarpment known as El Hank. The limestone and chalk cliffs rise 100 m above the surrounding plains. It contains numerous water springs along the rock-face, and in among the rockfalls and slips are gueltas. The vegetation typical of the area includes: Phoenix dactylifera, Adiantum capillus veneris, Hyoscyamus muticus, Tamarix sp., Acacia raddiana, Rhus tripantitus, Capparis decidua, Leptadenia pyrotechnica, Maerua crassifolia, Salvadora persica, Balanites aegyptiaca and Panicum turgidum.
