Etosha National Park is a game reserve in northwestern Namibia and one of the largest national parks in Africa. The park’s main attraction is a salt pan so large it can be seen from space but it’s also home to abundant wildlife that congregate around the waterholes throughout the park. The pan was originally a lake but over time the earth’s climate forced the rivers that once fed the lake to change course and flow into the Atlantic Ocean. Salt springs on the pan have now built up little hillocks of clay and salt which are used by some of the park’s wildlife as salt licks. In the wet season, parts of the pan form rainwater pools, and in particularly wet years the entire pan becomes a lake once more, standing at about 10cm deep and drawing thousands of migrating flamingos.
