The Simpson Desert is a large area of dry, red sandy plain and dunes in the Northern Territory, South Australia and Queensland in central Australia. It is the fourth-largest Australian desert, with an area of 176,500 km2 (68,100 sq mi). The desert is underlain by the Great Artesian Basin…. The Simpson Desert is an erg that contains the world’s longest parallel sand dunes. These north-south oriented dunes are static, held in position by vegetation. They vary in height from 3 m (9.8 ft) in the west to around 30 m (98 ft) on the eastern side. The largest dune, Nappanerica or Big Red, is 40 m (130 ft) in height.
