Tassili n'Ajjer (Berber: Tasili n Ajjer, meaning "Plateau of the Rivers") is a mountain range in the Algerian section of the Sahara Desert. It is a vast plateau in south-east Algeria at the borders of Libya, Niger and Mali, covering an area of 72,000 sq. km.

Prehistoric art

The range is also noted for its prehistoric rock art and other ancient archaeological sites, dating from Neolithic times when the local climate was much moister, with savannah rather than desert. The art depicts herds of cattle, large wild animals including crocodiles, and human activities such as hunting and dancing. The art has strong stylistic links to the pre-Nguni Art of South Africa and the region, executed in caves by the San Peoples before the year 1200 BCE. The range's exceptional density of rock art paintings-pictograms and engravings-petroglyphs, and the presence of many prehistoric vestiges, are remarkable testimonies to Neolithic prehistory. From 10,000 BCE to the first centuries CE, successive peoples left many archaeological remains, habitations, burial mounds and enclosures which have yielded abundant lithic and ceramic material. However, it is the rock art (engravings and paintings) that have made Tassili world famous as from 1933, the date of its discovery. 15,000 petroglyphs have been identified to date.

Geography

The Tassili n'Ajjer range extends from east-south-east to , and the highest point is Adrar Afao, 2158 m, at . 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.

The plateau is also of great geological and aesthetic interest: the panorama of geological formations with "rock forests" of eroded sandstone resembles a strange lunar landscape.[1]

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'Ajjer 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' referring to a time when the climate was repeatedly far wetter than today (see Neolithic Subpluvial).
