Adrar Plateau

The stony desert known as Reg de l'Adrar in Mauritania.

The Adrar Plateau (Berber: , lit. mountain) is a highland area of the Sahara Desert in northern Mauritania. It was heavily settled in the Neolithic era, and the more recent aridification has left much of the archaeology intact, most notable several stone circles and the later town of Azougui.

The plateau is known for its gorges, regs (stony deserts) and shifting sand dunes. It is home to a small human population, centred on the town of Atar.
