The Simpson Desert is a large area of dry, red sandy plain and dunes in Northern Territory, South Australia and Queensland in central Australia. The Simpson Desert is an erg that contains the world’s longest parallel sand dunes which formed as a result of wind erosion and sand deposition taking place over thousands of years. Some of the dunes stretch more than 100km in length. Also Lake Eyre (Kati Thanda), Australia’s largest salt lake, can also be seen at the lower right corner of the photo.

The local scenery on the ground is as follows.
