Location of the Atlas Mountains across North Africa

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 Sahara. Its highest summit is the 2,308 m (7,572 ft) high Lalla Khedidja in the Jurjura Range.[2]

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.
