White Surface of Lake Mackay, Australia22.5S 128.6E
Lake Mackay appears as a large, white expanse surrounded by red, arid land. This white color is due to the fact that it is an ephemeral salt lake, one of hundreds scattered throughout Western Australia and the Northern Territory.
The red dots in the eastern half of the lake are islands. This half of the lake appears slightly darker in color due to shallower waters and/or some form of desert vegetation or algae.
