Tell Atlas
The Tell Atlas (Arabic: الاطلس التلي) is a mountain chain over 1,500 km (932 mi) in length, belonging to the Atlas mountain ranges in North Africa, stretching from Morocco, through Algeria to Tunisia.
The ranges of this system have average elevations of about 1,500 m (4,900 ft) and form a natural barrier between the Mediterranean and the Sahara. Its highest summit is the 2,308 m (7,572 ft) high Lalla Khedidja in the Jurjura Range.
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 Mediterranean coast. Together with the Saharan Atlas to the south it forms the northernmost of two more or less parallel ranges which approach one another towards the east, remaining quite distinct from one another in Western Algeria and merging in Eastern Algeria. At the western end, it ends at the Rif and Middle Atlas ranges in Morocco. The Tell Atlas are also a distinct physiographic section of the larger Atlas Mountains province, which in turn is part of the larger African Alpine System physiographic division.
