Part 2 of my Namibia video features Deadviei and Sossusviei, perhaps the most photographed spot in Namibia. Deadviei is a beautiful but eerie sculpture garden created by mother nature’s extreme mood swings. Here she’s turned a former lake into a dead pan of white clay surrounded by giant red sand dunes. And scattered around the former lake bed are the remains of trees, starved to death by drought, their skeletal remains left to bake in the sun for hundreds of years, the dryness of the climate making it impossible for them to decompose. This week on National Geographic Weekend I talk about my trip to this ancient desert and about climbing the red sand dunes, which are some of the tallest in the world.
