Lakes of Ounianga in Sahara Desert (15 pics)
The Lakes of Ounianga consist of 18 lakes located in the heart of the Sahara Desert, in an extremely arid region of northern Chad where the average yearly rainfall is no more than 2 mm. They depend on an underground supply of ‘fossil’ water that fell on this area in ancient times when the Saharan climate was much wetter than it is today.
