The Sossusvlei, Namibia's famous highlight in the heart of the Namib Desert, is a huge clay pan, enclosed by giant sand dunes. Some of the spectacular hills of sand are, at a height of 300 metres, the highest in the world.
Only after a heavy rainfall, which is a rare event in this area, does the vlei fill with water. As the clay layers hardly allow any water infiltration, a turquoise lake will remain for quite some time.
