Editing Geography of Algeria (section)

=== The Tell ===
The fertile Tell is the country's heartland, containing most of its cities and population.<ref name=":0" /> Made up of hills and plains of the narrow coastal region, the several Tell Atlas mountain ranges, and the intermediate valleys and basins, the Tell extends eastward from the Moroccan border to the [[Isaak Mountain|mountains]] of the Grande Kabylie and the Bejaia Plain on the east.<ref name=":0" /> Its eastern terminus is the Soummam River.<ref name=":0" />

The best agricultural areas are the gentle hills extending 100 kilometers westward from Algiers; the Mitidja Plain, which was a malarial swamp before being cleared by the French; and the Bejaia Plain.<ref name=":0" /> The alluvial soils in these areas permitted the French to establish magnificent vineyards and citrus groves.<ref name=":0" /> By contrast, in the great valley of the Chelif River and other interior valleys and basins, aridity and excessive summer heat have limited the development of agriculture.<ref name=":0" /> The Grande Kabylie is a zone of impoverished small farm villages tucked into convoluted mountains.<ref name=":0" />
