Namib Desert, Namibia, satellite image. The desert sands (yellow) are piled up high by coastal winds (from left) to form the world's tallest sand dunes (ripples running mostly top to bottom). The dunes can reach 300 metres in height. This is a region of the Namib Desert designated the Namib-Naukluft National Park. The Sossusvlei clay pan (white and grey) was eroded and deposited by rare heavy rains that run off the high ground to the right. This image is around 60 kilometres across. Image acquired in visible and infrared wavelengths on 12 August 2000 by the Enhanced Thematic Mapper Plus (ETM+) sensor on NASA's Landsat 7 satellite.
