The Spitzkoppe, is a group of bald granite peaks or inselbergs located between Usakos and Swakopmund in the Namib desert of Namibia. The granite is more than 120 million years old and the highest outcrop rises about 1,728 metres (5,669 ft) above sea level. The peaks stand out dramatically from the flat surrounding plains. The highest peak is about 670 m (2,200 ft) above the floor of the desert below. A minor peak – the Little Spitzkoppe – lies nearby at an elevation of 1,584 m (5,197 ft). Other prominences stretch out into a range known as the Pontok Mountains.
