Salt Lakes of Chott el Djerid, Tunisia and Chott Melrhir, Algeria33.6N 8.3E
Two salt lakes are visible in the middle section of this image of northern Africa: the Chott el Djerid in Tunisia, right, and the Chott Melrhir in Algeria, left. The Grand Erg Oriental of the Sahara Desert begins south of the lakes.
Chott el Djerid is a large endorheic salt lake in southern Tunisia, at. It is the largest salt pan of the Sahara with a surface area of over 7,000 km² (some sources state 5,000 km²). Due to the extreme climate with annual rainfall of only 100 mm and temperatures reaching 50° C, water evaporates from the lake. In summer Chott el Djerid is almost entirely dried up.
Chott Melrhir is a large endorheic salt lake in northeastern Algeria. It has an area of about 6700 km² and is the largest lake in Algeria. It also lies almost entirely below the sea level; the lowest point of Algeria is located here. It regularly dries up and thus becomes a salt pan. Chott Melrhir is designated a Ramsar wetland of international importance.
