Simpson Desert Bounded by Lake Eyre and Rivers, Australia25.4S 138.2E
The Simpson Desert appears rusty red to the north and more tan to the south in this image of parts of central Australia. With a surface area of around 176 500 square kilometers, it spreads across the states of the Northern Territory, South Australia and Queensland.
It is bounded to east by the Georgina and Diamantina Rivers. Here, these rivers and others in Australia’s Channel Country, an arid area marked by a series of ancient flood plains from rivers which only flow intermittently (right side of image).
When very heavy rainfall occurs over time, these rivers flow into Lake Eyre, a great salt lake that generally remains dry. Here, the lake is greenish in color to the south and more tan to the north.
