At Mungo, in far south-western NSW, you’ll find undulating sandplains, ancient lakebeds, spectacular dunes and abundant fossils.
Mungo National Park and the wider Willandra Lakes Region World Heritage Area has a series of ancient lakes that once supported lush ecosystem.
Today the lake floors are dry saltbush plains; on their western sides they have crescent-moon shaped dunes known as lunettes, which were formed by prevailing winds when the lakes were full.
Over millennia, wind and water carve the lunettes – such as the Walls of China, pictured below into alien-looking formations.
Rain slowly washes away sand and soil, creating channels and ridges.
