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 (almost 1000 feet) above the desert floor. The dunes taper off near the coast, and lagoons, wetlands, and mudflats located along the shore attract hundreds of thousands of birds.
‘Namib’ means open space and the Namib Desert gave its name to form Namibia – “land of open spaces”. The park was established in 1907 when the German Colonial Administration proclaimed the area between the Swakop River and the Kuiseb River a game reserve. The park's present boundaries were established in 1978 by the merging of the Namib Desert Park, the Naukluft Mountain Zebra Park and parts of Diamond Area 1 and some other bits of surrounding government land.
The park has some of the most unusual wildlife and nature reserves in the world, and covers an area of 49,768 km² (19,215 square miles). It's an area far larger than Switzerland, roughly the size of the US states New Hampshire and Vermont combined. The region is characterised by high, isolated inselbergs and kopjes (the Afrikaans term for rocky outcrops), made up of dramatic blood red granites, rich in feldspars and sandstone. The easternmost part of the park covers the Naukluft Mountains.
