The river that never reaches the sea

The Okavango River flows over a thousand kilometres from Angola's highlands, then fans out across Botswana's Kalahari Desert and simply disappears — soaked up by sand and evaporation instead of emptying into any ocean. The seasonal flood, arriving in the dry season, turns the desert into one of Africa's richest wildlife habitats.
