Namibia's Death Valley is located in a white depression in Sossusvlei. There is no grass growing in it and no signs of life, hence the name. Death Valley was not always so dead. More than 900 years ago, there were rivers and lush vegetation here. Unfortunately, something happened later, and sand dunes moved here, blocking the river. In addition, due to climate change and no rainfall for many years, the trees and grass here quickly died.
