Deadvlei, Namibia
No, the above images are not surrealist paintings. They’re photographs of “dead valley,” where trees stand against a background of the highest sand dunes in the world. Once a thriving forest, the approaching desert has killed all life.
Sadly, the mining company that owns the caves could no longer afford to keep the massive pumps going to clear the chamber. I believe the pumps were shut down a few years ago and the cavern is refilled with water. The crystals are growing once again, but no one will ever see it.
