Plain of Tamlelt
On the eastern fringes of the Atlas, high plains and shallow depressions interrupt the mountain chains. The Tamlelt plain lies among the low ranges of the eastern High Atlas, while the Chott Tigri basin is bordered by Jebel Lakhdar and Jebel Bouarfa. Sparse vegetation and seasonal water distinguish this open country from the better-watered mountain slopes farther north. The land falls away towards the dry interior on the edge of the Sahara.
