Simpson Desert – Surface Surveys
Simpson Desert – Australia
Protected in 1972 an Australian Conservation Park
With an area of 68,000 square miles and located in the “red center” of Australia, the Simpson Desert is the world’s largest sand desert that also contains the longest parallel sand dunes in the world. The main characteristic of the Simpson Desert is its lines of long, straight, and parallel dunes that vary in color from vibrant red to white. Individual dunes can extend continuously for over 150km.
The creation of the desert began 270 million years ago after glaciers in the area melted. Sediment of sand, mud, and small stones carried by water and glaciers, landed in the depressions of the earth and formed a layer with freshwater lakes above it. About 1.8 million years ago, changes in climate dried up all the lakes and rivers creating the desert environment it is today.
Aboriginal peoples have occupied and managed the desert lands and waters for thousands of generations. No maintained roads cross the desert, however, ancient song lines that reflect the creation of desert landforms and provide geographical references, enabling Wangkangurru Yarluyandi people to navigate their way across the desert.
