Part of the Illizi province (wilaya), in the south-eastern corner of Algeria, is visible here. The upper half of the image shows the orangey sand dunes of the Sahara Desert, while the lower half shows the brown slopes of the Tassili n’Ajjer mountain range.

The name of the range means “Plateau of the Rivers” in Tamazight. As the name suggests, the topography of the range is deeply indented, eroded by rivers in the past. Today the range is drier, although due to the altitude and the water-holding properties of the sandstone, the vegetation is somewhat richer than the surrounding desert.
