Chad - Tibesti Expedition 2015
Please visit my site for the full story
I’ve put together some video for you of my recent expedition to one of the Sahara’s most remote corners. Only one previous expedition has reached the Ouri plain. That was about 15 years ago. And given the difficulties, I can’t see anyone else trying it anytime soon.
Absolutely Nowhere in CHAD
Only some 400 tourists visit Chad each year. If you want to step out of your life and disappear into a vast, stunning and varied landscape; if youd have a keen sense of adventure; don't mind 130 degree heat midday or winds blowing dust through your tent at night, then Chad is the place to go. This huge landlocked country covers 495,753 square miles. If the human population is approximately ten million, the cattle and camel population seems triple that number. Part one of thios clip features our vans traveling through the landscape, touching the Sahel, savannah, desert and Ennedi region. Part two highlights the pulse of Chad - its people, wildlife, rivers and markets. Timeless, colorful and dare I say quirky, I have never experienced anything like this place.

The Lakes of Ounianga in the Sahara Desert, Chad
The Lakes of Ounianga in the Sahara Desert, Chad
Lakes of Ounianga are a series of 18 lakes in the Sahara Desert, in North-Eastern Chad, occupying a basin in the mountains of West Tibesti and Ennedi East. The names of the lake groups are derived from the name of a village nearby. It was added as a UNESCO World Heritage site in 2012, the lakes are in a hot and hyper-arid desert that features a rainfall of less than 2 millimeters a year. The lakes are situated in a shallow basin below sandstone cliffs and hills, from where the ancient water flows. Remarkably, this unique hydro-logical system is able to sustain the largest permanent freshwater lakes to be found in such an arid desert environment anywhere in the world. The lakes are remnants of a single large lake, probably tens of kilometers long, that once occupied this remote area approximately 14,800 to 5,500 years ago. As the climate dried out during the subsequent millennia, the lake shrank, and large, wind-driven sand dunes invaded the original depression, dividing it into several smaller basins.
The 18 lakes altogether, in two groups about 40 km apart. They vary greatly in chemical composition, some being so salty that they can only support the most basic forms of life, while others are fresh enough to provide habitat for aquatic plants, fish and a diversity of other species. The largest and most biologically important lake is Lake Teli and it has a surface area of 4.4km2 and a maximum depth of 10 meters. Its water is fresh, and supports an abundance of life. The sandy substrate is highly porous, so water flows freely underground between Lake Teli and 13 other smaller lakes in the eastern group. Further west, across the dunes and sandstone ridges that characterise this part of the Sahara, the second group of four lakes (known as Ounianga Kebir) is found, dominated by Lake Yoan (3.6 km2 and 27 m deep). This is a hyper saline lake which supports only algae and a few other micro-organisms. Rocks around its shores are encrusted in white salt deposits, and a sprawling village of some 9,000 people is spread amongst the nearby hills and dunes. There is a customs post, as this is the last habitable place on the main trans-Sahara truck route through to Libya.
The lakes’ dark surfaces are almost completely segregated by linear, orange sand dunes that stream into the depression from the northeast. The almost-year-round northeast winds and cloudless skies make for very high evaporation rates; an evaporation rate of more than 6 meters per year has been measured in one of the nearby lakes. Despite this, only one of the ten lakes is saline.
The reason for the apparent paradox—fresh water lakes in the heart of the desert—is that fresh water from a very large aquifer reaches the surface in the Ounianga Depression. The aquifer is large enough to keep supplying the small lakes with water despite the high evaporation rate. Mats of floating reeds also reduce the evaporation in places. The lakes form a hydrological system that is unique in the Sahara Desert.

Guelta d'Archei | Amazing lake in Sahara Desert
Guelta d'Archei amazing place in the heart of the Sahara Desert, It is located in the Ennedi Plateau, It is located in the Ennedi Plateau, in north-eastern Chad, south-east of the town of Fada. The Guelta d'Archei is inhabited by several kinds of animals, most notably the Nile crocodile, one of the last palace where Nile crocodiles are found in Sahara. The Middle Holocene remains, as well as rock paintings, indicate that this species once thrived across most of today's Sahara Desert and in swamps and rivers along South Mediterranean shores. The small group of surviving crocodiles in the Guelta d'Archei represent one of the last colonies know in the Sahara today; the Tagant Plateau colony in Mauritania has likely been extinct since 1996. The word Guelta means wetland, The reservoirs of this wetland is supported by groundwater. Guelta d'Arshey is surrounded by extensive desert areas, which make access to this awesome place.
Guelta Archei is a watering place for camels located in the Ennedi plateau. The guelta is also inhabited by a very small number ( between 1 and 7 there are only estimations) of the Nile crocodile. This is one of the last colonies of crocodiles in the Sahara. There is another colony in Mauritania. You can see the crocodile on the right edge. Image by Flickr user Hannes Rada
The Guelta d'Archei is the most famous permanent water source in the Ennedi region of Chad. Everyday, hundreds of camels are herded into the guelta in order to drink. That particular morning, one of the herdsmen was claiming that 850 of them were at once in the guelta. The value of a camel ranges between 250 EUR up to 800 EUR (and more). They are mainly raised for the milk they produce and as transport animals (not for the meat). Image by Flickr user A.Bielecki
