Saharan Atlas
The Saharan Atlas includes a series of subranges: the Ksour Range in the west, the Amour Range in its central and the Ouled-Naïl Range at its eastern end. It also includes the Aurès (Belezma), the Hodna Mountains, the Nememcha Range and the Zab Mountains. The Tell Atlas and the Saharan Atlas merge in the east to join together into the Tébessa Range and the Medjerda Mountains.
