Sossusvlei is a salt (salar) and clay desert in the Namib Desert, located in the Namib Naukluft Park in Namibia. It consists of a wadi penetrating from the town of Sesriem for about 60 km from east to west into the dune area of the desert.
Fed by the Tsauchab River, the area is known for its high red sand dunes surrounding the area, forming a sea of sand, the Sossusvlei Dunes. The sparse vegetation, which includes Acacia erioloba, is only lightly watered by the Tsauchab River, whose water is quickly lost in the dry clay.
