Stretching from the Moroccan border the [[Tell Atlas]], including the [[Djebel Babor]] formation, is the dominant northwestern mountain range. Stretching more than 600 kilometers eastward from the Moroccan border, the high plateau area (often referred to by the French name ''[[Hautes Plaines]]'' or ''Hauts Plateaux'') consist of undulating, steppe-like plains lying between the Tell and [[Saharan Atlas]] ranges.<ref name=":0" /> The elevation averages between {{Convert|1100-1300|m}} in elevation in the west, dropping to {{Convert|400|m}} in the east.<ref name=":0" /> The climate is so dry that these plains are sometimes thought of as part of the [[Sahara]].<ref name=":0" /> The plateau area is covered by alluvial debris formed when the mountains eroded.<ref name=":0" /> An occasional ridge projects through the alluvial cover to interrupt the monotony of the landscape.<ref name=":0" />

Higher and more continuous than the Tell Atlas, the Sahara Atlas range is formed of three massifs: the [[Ksour Range]] near the Moroccan border, the [[Amour Range]], and the [[Ouled-Naïl Range]] south of [[Algiers]].<ref name=":0" /> The mountains, which receive more rainfall than those of the High Plateaus, include some good grazing land.<ref name=":0" /> Watercourses on the southern slopes of these massifs disappear into the desert but supply the wells of numerous [[Oasis|oases]] along the northern edge of the desert, of which [[Biskra]], [[Laghouat]], and [[Béchar]] are the most prominent.<ref name=":0" />
