The Tassili n'Ajjer (It is a name from the Berber language, and it is known as "التاسيلي" (Tassili) in Arabic and its English name is: "Tassili Plateau") is a mountain range in the Sahara desert in southeast Algeria, North Africa. It extends about 500 km from 26°20′N 5°00′E east-south-east to 24°00′N 10°00′E, and the highest point is Adrar Afao, 2158 m, at 25°10′N 8°11′E. The nearest town is Djanet, about 10 km southwest of the range.

Much of the range, including the cypresses and archaeological sites (see below), is protected in a National park, Biosphere Reserve and World Heritage Site, named the Tassili n'Ajjer National Park.

Geology

The range is composed largely of sandstone. Erosion in the area has resulted in nearly 300 natural rock arches being formed, along with many other spectacular landforms.

Ecology

Because of the altitude and the water-holding properties of the sandstone, the vegetation is somewhat richer than the surrounding desert; it includes a very scattered woodland of the endangered endemic species Saharan Cypress and Saharan Myrtle in the higher eastern half of the range.

The ecology of the Tassili n'Aljer is more fully described in the article West Saharan montane xeric woodlands, the ecoregion to which this area belongs. The literal English translation of "Tassili n'Ajjer" is 'Plateau of the rivers'; indicating a time when the climate was far more wet than today.

Prehistoric art

The range is also noted for its prehistoric rock paintings and other ancient archaeological sites, dating from neolithic times when the local climate was much moister, with savannah rather than desert.
