Located south of the main road between the towns of Akjoujt and Atâr in the Adrar region, this is an area of rock escarpments and cliffs on the edge of the Adrar plateau. There are numerous wells and springs issuing from faults in the rock. Permanent and semi-permanent gueltas form in rocky basins within the escarpment and a wetland called a grara forms in a large lowland depression at the base of the escarpment after the rains. The vegetation of the area includes Phoenix dactylifera, Hyoscyamus muticus, Tamarix sp., Acacia raddiana, Capparis decidua, Leptadenia pyrotechnica, Maerua crassifolia, Salvadora persica, Balanites aegyptiaca and Panicum turgidum.
