Dead Vlei means Dead Valley. It’s a popular destination in the Namib desert famous for its dead trees, hence the name. To the West a small part of the dried mud bed in the dune locked valley has subsided, and there, amazingly, a handful of trees, probably at least a hundred years old due to a very slow rate of growth, have managed, God knows how, to survive!
