Baku, August 8, AZERTAC Stretching a mind-boggling 144km by 77km, South Australia`s Lake Eyre, also called Kati Thanda–Lake Eyre, truly is a natural wonder. Its seemingly-endless expanse of shimmering salt crystals lure travelers year-round, but the real magic happens when the lake is flooded by desert rain. Once every few years, networks of channels, streams and floodplains converge in Kati Thanda-Lake Eyre National Park, bringing with them an abundance of wildlife, stunning natural beauty and dreamlike pink and orange hues. The lake has only filled to capacity three times in the last 150 years.Located 647km north-east of Adelaide, Kati Thanda-Lake Eyre is Australia`s biggest salt lake and was formed approximately 200 million years ago and is the lowest point below sea level on the Australian continent.When the lake`s water level is low, its glittering crystalized surface stretches as far as the eye can see. When it floods, waterbirds descend in their thousands, fish converge in channels and wildflowers blanket floodplains. As water begins to evaporate, the lake takes-on a spectacular pink hue caused by a pigment found within a specific type of salt-loving algae.
