The Atlas Mountains (Arabic: جِبَال ٱلْأَطْلَس, romanized: jibāl al-ʾaṭlas /ʒibaːl al atˤlas/, Tamazight: ⵉⴷⵔⴰⵔⵏ ⵏ ⵡⴰⵟⵍⴰⵙ Idrarn n waṭlas) are a mountain range in the Maghreb. It separates the Mediterranean and Atlantic coastlines from the Sahara Desert. It stretches around 2,500 km (1,600 mi) through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, which is in southwestern Morocco, with an elevation of 4,167 metres (13,671 ft). The Atlas mountains are primarily inhabited by Berber populations. The terms for 'mountain' are adrar and adras in some Berber languages. These terms are believed to be cognates of the toponym Atlas. The mountains are also home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct.
