Deadvlei

Deadvlei is a white clay pan located near the more famous salt pan of Sossusvlei, in a valley between the dunes in the Namib-Naukluft Park in Namibia. Also written DeadVlei or Dead Vlei, its name means "dead marsh". The pan also is referred to as "Dooie Vlei" which is the Afrikaans name. There are many references to the site on the Internet, its name often being translated erroneously in terms such as "dead valley"; a vlei is not a valley. Nor is the site a valley; the pan is a desiccated vlei.

Dead Vlei has been claimed to be surrounded by the highest sand dunes in the world, the highest reaching 300–400 meters, named "Big Daddy" or "Crazy Dune", resting on a sandstone terrace.
