Red Dunes and a Pan of Dead Trees

Sossusvlei is a clay pan in Namibia's Namib-Naukluft National Park, surrounded by some of the tallest dunes on Earth. Vlei is an Afrikaans word for a shallow marsh or pan. The Tsauchab River reaches it only after rare heavy rains, filling it briefly with water.

The dunes are red because iron oxide coats the sand grains. Big Daddy rises about 325 m, and Dune 45, about 45 km from Sesriem gate, is a favorite climb at sunrise. The Namib is often called the oldest desert in the world, dry for tens of millions of years.

Nearby Deadvlei holds dead camel thorn trees, hundreds of years old, that stand black against white clay because the air is too dry for decay. The area is part of the Namib Sand Sea, listed by UNESCO in 2013. Sesriem Canyon, a narrow gorge, lies near the park entrance.
