This photo was taken in northern parts of Namibia, near Purros, overlooking part of the Skeleton Coast National Park. As you can see, this is an extremely dry area.
The mix of the cold water from the South Atlantic Ocean, and the hot air from the Namibian dessert, regularly causes mist at the sea. Many ships, on their way to India and Indonesia found themselves lost in these mists, quite ofter resulting them to run aground on the barren coast that doesn't have much to offer shipwrecked crews.
This resulted in the name "Skeleton coast".
