The Tassili Tadrart (also known as the Red Tadrart) is the southern extension of the Tadrart Acacus. It is located in the south-east of Algeria, bordering Libya to the east and the Niger to the south. The mountain range is criss-crossed by west-east orientated, gorge-like wadis, of which In Djaren is the largest.
The Tassili Tadrart has magnificent rock paintings that cover a long chronological span from the early Neolithic to modern times. Walls and overhangs at the bottom of the wadis are littered with rock paintings and rock engravings that document the climate change of the area from a savannah 10,000 years ago to a desert 5,000 years ago. The rock art changed over time from wild fauna such as elephants, rhinos, giraffes, antelopes, wild cattle to domesticated animals such as sheep, horses and finally camels.
