Gibber plain, near Winton, western Central Queensland.The landscape shown here in this semi-arid region is a reminder that most of Australia's desert regions are not covered by sand dunes (though these are extensive in Australia), or by clay surfaces, but rather by rocky surfaces of various kinds.Gibber plains are made up of many small rocks, the lighter sands and clays having been washed away or blown away over time. In some places the rocks almost seem to have been laid down like mosaic tiles, forming what is called 'desert pavement'.
