Golden Sands of the Grand Erg Oriental, Algeria and Tunisia31.5N 7.4E
Greenish sediments can be seen in the Gulf of Gabes off the coast of Tunisia between the Kerkennah Islands, an archipelago with an area of 160 km2, and Djerba (south of the former), the largest island of North Africa at 514 km².
The large tan area inland, west of Djerba, is the Chott el Djerid, a large endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara Desert. Moving southward, one comes to the golden yellow expanse of the Grand Erg Oriental, a sand dune sea stretching across Algeria to Tunisia.
