flora&fauna
The Altiplano was formed millions of years ago by sediments washed down from the mountains to fill a deep valley that formed between two Andean chains as they were pushed up from the seabed. When the sea eventually retreated, it left behind giant salt lakes and saltpans. But as dry as it is, the Altiplano is hardly devoid of life. Animals and birds thrive here: Condors, herds of alpacas and vicunas, grey foxes and vizcachas all flourish in the ochre desert, and the algae-rich salt lakes support formidable colonies of all three species of South American flamingos.
