Salt of the earth

At Lake Tyrrell, southern Australia, the sky meets the Earth in a dazzling display. The state of Victoria's largest salt lake was formed around 120,000 years ago. Over time, climate change caused water levels to drop; these days, the lake is normally dry, except in winter when it's covered in over 5 centimetres of water. The name 'Tyrrell' comes from the local Wergaia word for 'sky,' a nod to the Boorong Aboriginal People's interest in astronomy. Spanning more than 180 square kilometres, Lake Tyrrell is a haven for wildlife, including Mallee reptiles, kangaroos and emus.
