Lake Gairdner, Australia
In bright shades of blue, this false-colour image, acquired in April 2015, shows Lake Gairdner and nearby smaller lakes and lagoons such as lakes Everard (west), Macfarlane (southeast), Hart and Hanson (northeast) and Island Lagoon (east). Lake Gairdner is the third largest salt lake in Australia and part of a closed drainage basin that is located to the north of the Eyre peninsula and the stony hills of the Gawler Ranges in South Australia. Together with Lakes Everard and Harris (northwest) and surrounds, Lake Gairdner forms a protected national park that is well preserved. While very hot and devoid of surface water in summertime, the park shelters many species of plants and birds, feral camels, emus and kangaroos in Spring. For race fans, the salt flats are a site of annual attempts to improve various land speed records.
