Marks the beginning of the Sahara desert. It lies between the High Atlas Mountains and the edge of the Sahara Desert. It is an extinct volcano situated to the south of the Atlas Mountains and Dades Gorge. Jutting up out of a region full of much eroded sedimentary plateaus, Sarho is framed by small isolated farms. Its inhabitants, the Ait Atta, move from season to season between the Sarho region and the Atlas Mountains to seek food for their animal herds.
