Sahel Corridor

The desert east of Tindouf lies between the stony plateaus of the western Sahara and the great sand ridges of the Erg Iguidi. South of the basin, the ancient rocks of the Réguibat ridge emerge in the Eglab massif; northward the Hamada of the Draa spreads across a broad plateau. Dry valleys, bare rock and sand form a severe landscape in which settlements are separated by long distances.
