Tademait Plateau
The Tademaït is an immense stony plateau in the Algerian Sahara, bordered by oasis chains on several sides. Its surface forms a hamada of bare rock and dark stones, with deeply eroded edges above the surrounding depressions. The Gourara lies to the north, the Touat to the west and the Tidikelt to the south. In their gardens, underground channels called foggaras bring water to palm groves at the margins of the dry plateau.
