Namibia is soul-stirring. Here on the southwest edge of Africa, burnt-orange dunes rise a thousand feet high against a cobalt sky. Inside are diamonds, tucked into the mountains of sand by waves and wind. The coastal desert is washed by the relentless ocean, while inland, the sun bakes the plains into a cracked puzzle of dried mud, pocked with enough grass and thornbush to sustain desert rhinoceros and other rare species. There is water here, too, although its presence is subtle. In the stark Etosha salt pan, waterholes attract game pursued by feline predators. Springbok, oryx, kudu and dik-dik run to elude them in a great and ancient desert dance.
