The
Simpson Desert is located in central Australia, near the
borders of Queensland, New South Wales, South Australia and the Northern
Territory. It is real frontier country, still as wild and untamed as it
was for the first European pioneers 150 years ago. With undulating sand
dunes and challenging desert tracks, this is 4X4 outback country at its
best. Most of the Simpson Desert's attractions are within a day-trip's
range south to south-west of Alice Springs, but their vast, rugged beauty
will keep you in the region as long as your itinerary allows.
Dune
Geography
Over one
thousand one hundred parallel, white, red, yellow and orange sand dunes
rise across the Simpson Desert, some extending continuously in a North
West - South East direction for over 200 kilometres. The dunes comprise
75 percent of the total desert area and are formed by winds scouring the
surface of deposited sediment, resulting in the accumulation of sand in
leeside mounds on the northern margins of the floodplains.
Wildlife
While the
availability of water has a pronounced effect on diversity, over 180 species
of birds, over 30 species of reptile and up to 44 species of native mammal
are now found throughout the desert. Grassy floodplains provide the major
food source and the success or otherwise of wildlife is dependent on changing
patterns of rainfall, drought, competition for food sources and shelter,
predators and changes in fire regimes.
Wedge-tailed
eagles are often seen soaring majestically above the desert and then landing
on the apex of a perfectly sculptured live crest of sand. Camels are free
ranging and common inhabitants of the desert. |
