The 100 m false-colour image of 11 October 2015 shows us the Namib-Naukluft National Park, encompassing part of the Namib Desert. The winds that bring in the fog are also responsible for creating the park’s towering sand dunes, whose burnt orange color is a sign of their age. The orange color develops over time as iron in the sand is oxidized, like rusty metal; the older the dune, the brighter the color. These dunes are the tallest in the world, in places rising more than 300 meters above the desert floor.
