Original Text


Visible from space, the Okavango Delta is Africa's largest remaining intact wetland wilderness. This shining delta in landlocked Botswana is the jewel of the Kalahari, more valuable than diamonds to the world's largest diamond producer and celebrated in 2014 as our planet's 1000th UNESCO World Heritage Site. Now, what you see here are the two major tributaries, the Cuito and the Cubango, disappearing up north into the little-known Angolan highlands. This is the largest undeveloped river basin on the planet, spanning an area larger than California. These vast, undeveloped Angolan watersheds were frozen in time by 27 years of civil war. In fact, Africa's largest tank battle since World War II was fought over a bridge crossing the Okavango's Cuito River. There on the right, disappearing off into the unknown, into the "Terra do fim do mundo" — the land at the end of the earth, as it was known by the first Portuguese explorers.
