Chott el Jerid and Chott Melrhir, Tunisia and Algeria33.8N 9.5E
Moving southward from the fertile green northern coast of Tunisia (right) and Algeria (left), towards the sandy Sahara Desert, one comes across several large salt lakes.
The largest visible here is the Chott el Djerid, an endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara with a surface area of over 7,000 km².
To the west of Chott el Djerid is Chott Melrhir, an endorheic salt lake in northeastern Algeria. It has an area of about 6700 km² and is the largest lake in Algeria. Like its neighbor to the east, it regularly dries up thus becomes a salt pan. Chott Melrhir is designated a Ramsar wetland of international importance.
