Salt of the earth. Lake Tyrrell, Victoria, Australia

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 changes caused water levels to drop; these days, the lake is normally dry, except in winter when it's covered in around 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 70 square miles, Lake Tyrrell is a haven for wildlife, including Mallee reptiles, kangaroos and emus.

In recent years, the lake has become a tourist hotspot. People come from all over the world during the winter months, drawn by its mirror-like surface that reflects the endless Australian sky, making it the perfect photo op. The salt formations on the lakebed also provide a stunning backdrop for photographs. At night, it becomes the perfect place for stargazing, offering the chance to marvel at the constellations of the Southern Hemisphere.
