Geocache Description:


Chott el Jerid

Dry salt lake 'Chott' is the word used in Tunisia for lakes that stays dry through the hot season,
but which has some water in the winter.


Most of the year the Chott el Jerid holds little or no water, and can be crossed by foot or by vehicle. During these periods, the Chott is cut by small creeks, transporting surplus water from the rainy season. The chott has little economic importance, as its water is salty, and the immediate surrounding land is thereby prevented from agricultural development. All settlements along the Chott are located at a distance from the shore. There are no fisheries in the Chott, since it being dry most of the year.

Formation of this lake. Chott el Jerid was some thousand years ago part of the Mediterranean. A natural dike then detached it from the Sea. The dry local climate, hot and very little rain, has caused the exsiccation and mineralization.



Some of the most prosperous oases of Tunisia, Tozeur, Nefta, Kebili, Douz, and Zaafrane, are located along the northern and southern shores of the Chott. The trip is highly recommended, and offers some great sights, especially when the sun shines on the salty surface, and reflections together with the heat gives startling optical effects.
Earlier, many caravans were lead astray by the mirages out on the Chott. The largest, the Chott el Jerid, covers 5,000 sq km at the most, and lies in the middle of Tunisia, close to the Algerian border. Chott el Jerid was some thousand years ago part of the Mediterranean Sea. The chott is easily accessed, as an elevated causeway has been built across it, from Kebili to Tozeur.
