Location of the Atlas Mountains across North Africa

The Tell Atlas (

Arabic: الاطلس التلي, al-ʾaṭlas al-tlī) is a mountain chain over 1,500 km (932 mi) in length, belonging to the Atlas mountain ranges in North Africa, stretching mainly across northern Algeria, with ends in both north-eastern Morocco and north-western Tunisia
.

The ranges of this system have an average elevations of about 1,500 m (4,900 ft) and form a natural barrier between the Mediterranean and the

Several large cities such as the Algerian capital, Algiers, with ~1,500,000 residents (2005) and Oran with ~770,000 residents (2005) lie at the base of the Tell Atlas. The Algerian city Constantine with approximately 505,000 residents (2005) lies 80 km inland and directly in the mountains at 650 meters in elevation. A number of smaller towns and villages are situated within the Tell; for example, Chiffa is nestled within the Chiffa gorge.

Geography

The Tell Atlas runs parallel to the

physiographic
division.

The Tell Atlas and the Saharan Atlas form two natural barriers, the first against the

Mediterranean and the second against the Sahara. Between them lies the valley of the Chelif
and various lesser rivers.

South of the Tell Atlas is the high plateau of the Hautes Plaines (~1000 m in elevation) with level terrain where water collects during the wet season, forming large shallow salt lakes which become salt flats as they dry. Agriculture includes grazing of sheep and goats on the grass in better-watered high plateau areas and some farming; dry-land barley is grown there.[3]

The Chelif is a 725 km long river with headwaters in the Tell Atlas to its discharge into the Mediterranean. The Chelif is characterized by an extremely fertile valley. Other noteworthy rivers having their sources in this range are the Medjerda and the Seybouse River. Only seasonal streams are found flowing south from the Tell Atlas.

Climate and vegetation

The Tell Atlas has a typical

cork oak. In the summer a hot, dry wind, the Sirocco
, blows north from the Sahara across the Tell Atlas, causing dusty, dry conditions along the northern coast of Africa.

Despite the arid climate, some agriculture for barley and wheat farming is found in the Tell Atlas region.
