East of village of Merzouga lies Erg Chebbi in southeastern Morocco. It is one of two Saharan ergs in the northwest African nation. Its distinctive ergs — large dunes formed by wind-blown sand — reach up to 150 meters high, and form a composite erg 22 km long (north-south) and 5 km wide.
Large parts of the Sahara are made up of such “wandering dunes” that continuously change shape as a consequence of the shifting of the fine sand.
