Approximately 5% of the Simpson Desert is made up of sand dunes. The parallel, wind-blown sand dunes that make up the spectacular parallel dunal desert occupy about 10 000 sq km of the entire desert, which is about 200 000 sq km in area. The remainder of the desert is sandy plains, spinifex grasslands, saltbush plains and salt lakes. If you would like more information, go to the related link below.

What is special about the Simpson desert?
The Simpson Desert is one of several deserts in Australia, and covers about 180,000 square kilometres in central Australia, spanning the Northern Territory, Queensland and South Australia. It is the fourth-largest desert in Australia. There are no maintained roads across the desert, but numerous 4Wd tracks. In 2008, for the first time, the Simpson Desert was closed to tourists from December 1 until mid-March in 2009. This was because of the high costs of rescuing tourists who foolishly try to cross the desert or take on the sand-dunes in the hottest months of the year. It is also to prevent the deaths that occur from this. However, it is also for the health of the desert - to give the desert some time to "regenerate" from the many tourists also. The Simpson Desert has some interesting things to see. These include: * Dalhousie Springs, where you can enjoy hot springs * Kaliduwarry Waterhole, a permanent supply which stretches for some 30 kilometres * the Birdsville Track * the Old Ghan Heritage Track * Chambers Pillar, a 50m sandstone pillar rising up from the desert plain * the Ewaninga Rock Carvings Conservation Reserve * Poeppel Corner, a remote spot where where three state borders meet * incredible red-orange, rippling sand dunes - there are over 1100 sand dunes all running parallel in a north-south direction * colourful sunrises and sunsets, unlike those you will see anywhere else

What percentage of a desert is made up of sanddunes?
It depends on which desert! I'm living in the middle of one and it has no sand dunes at all. A desert isn't necessarily a place of hot, dry sand and sun. A desert is merely any place that has an extremely low annual rainfall. Some deserts are indeed hot and dry with rolling sand dunes, and some are indeed almost nothing but rolling sand dunes. However, most deserts are merely dry and covered in grasses and small salty bushes that require very little water to survive. Deserts can also be lush and full of life along rivers that flow through them from areas where it does rain more often (such as nearby mountains); and some of the deserts on this planet are covered in ice all year.
