Plain of Tamlelt
The Tamlelt plain occupies a depression within the eastern High Atlas, where low ranges give way to dry open ground. The northern part receives streams from the high plateaux, their waters largely lost to infiltration and evaporation. In the south, channels including the Oued Haloua flow towards the Bouanane and the Guir. Springs along the edges of the basin provide water in a landscape otherwise marked by the aridity of the Saharan fringe.
