Plain of Tamlelt

In the eastern High Atlas, low mountain chains enclose the broad Tamlelt plain. Streams from the high plateaux to the north enter the depression and often disappear through seepage or evaporation. At the southern edge, other channels drain towards the Oued Bouanane and the Guir. The dry plain and its bordering hills form part of the transition from the Atlas uplands to the lands and oases on the northern fringe of the Sahara.
