Erg Amatlich

This stretch of the western Sahara lies near Tichla, on the desert plain of Tiris. Low rocky hills rise from the surrounding hamada, and the nearby depression of Sebjet Dalaat Asder marks one of the area's salt flats. Across Tiris, such basins collect the runoff of occasional rains, while alluvial fans and fractures in the rock offer places where groundwater can accumulate.
