Salt Flats of Lake Eyre, Australia28.1S 137.2E
During years of especially high rainfall, all the riverbeds in the vast, mostly flat, arid and semi-arid areas of Australia lead inland towards Lake Eyre in central South Australia. Most of the water reaching Lake Eyre comes from the river systems of semi-arid inland Queensland, roughly 1000 kilometres to the north.
Lake Eyre itself lies approximately 16 metres below sea level, and usually contains only salt. In flood years it fills and for a short time undergoes a period of rapid growth and fertility: long-dormant marine creatures multiply and large flocks of waterfowl arrive to feed and raise their young before the waters evaporate once more. Here, the lake appears mostly dry and salty, as evidenced by the white coloring.
