Algeria’s southern part includes a significant portion of the Sahara. To the north, the Tell Atlas form with the Saharan Atlas, further south, two parallel sets of reliefs in approaching eastbound, and between which are inserted vast plains and highlands. The vast mountain ranges of Aures and Nememcha occupy the entire northeastern Algeria and are delineated by the Tunisian border, with the highest point of Mt. Tahat (2,918m).

The local scenery on the ground is as follows.
