Mungo National Park

Listen for a moment. There is wind moving across dry saltbush, a crow calling somewhere far off, and almost nothing else. Underfoot the ground is fine and pale, part sand and part clay. Ahead of you a long curve of eroded dunes glows white and orange in the light. This is Mungo National Park, in the far southwest of New South Wales. It feels empty. But this flat, quiet basin holds one of the longest records of human life anywhere on Earth.

The first surprise is that you are standing at the edge of a lake. You will not see water, because there has been none here for thousands of years. Lake Mungo is a dry lake bed. It is one of a chain of ancient lakes known as the Willandra Lakes. During the last Ice Age, rivers fed these basins. They filled with fresh water, fish, shellfish and waterbirds. For people living here, it was a place of plenty.

As the climate became drier, the lakes slowly emptied. Scientists generally place the final drying at roughly eighteen thousand years ago. Over the long wet centuries, steady westerly winds blew sand and clay off the shoreline. That material piled up along the eastern edge of the lake. It formed a long, crescent-shaped dune called a lunette. The word simply means a small moon, after its curved shape. That lunette is the pale ridge you can see on the horizon.

This lunette has a famous name: the Walls of China. Locals say the name comes from Chinese workers on the surrounding sheep stations in the nineteenth century. Some thought the dunes looked like the Great Wall of their homeland. That story is popular, though it is told more often than it is documented. Whatever its origin, the name stuck. Today the walls are a maze of ridges, gullies and small pinnacles, carved by wind and rare, heavy rain.

That erosion is the key to everything here. Each storm and each windy season removes a little more sand. In doing so, it exposes old surfaces buried for tens of thousands of years. Hearths, stone tools, shell middens and animal bones come to the surface. A midden is a heap of food remains, like shells and bones, left at an old campsite. Here the land itself keeps opening its archive, one layer at a time.

In 1968, geologist Jim Bowler was studying these ancient lake shorelines. He noticed burnt bones eroding from the sand. They turned out to be the remains of a young woman. She had been cremated, her bones broken, then burned again and buried. She became known as Mungo Lady. Her remains are dated to around forty thousand years ago. That makes this one of the oldest known cremations in the world.

In 1974, Bowler found a second burial nearby. This was a man, laid on his back, his hands crossed over his body. His remains had been sprinkled with red ochre, a natural iron-rich pigment. The ochre was carried here from some distance away. Mungo Man is also dated to roughly forty thousand years ago. Together, these two burials changed how the world understood the story of early Australia, and of human ritual itself.

Here is a detail many visitors do not expect. These are not just old bones. They are ancestors. For decades the remains were held in a university far from here. Aboriginal communities campaigned for their return. Mungo Lady came home in 1992. Mungo Man was returned to country in 2017, carried back in a slow procession across the outback. Those moments of return are now part of the story of this park.

The traditional owners of the Willandra Lakes are three Aboriginal groups. They are the Paakantyi, also spelled Barkindji, the Mutthi Mutthi and the Ngiyampaa. Together they share in the care of this land with the parks service. Aboriginal Discovery Rangers lead many of the guided walks. When you hear a ranger explain a stone tool or a fireplace, you are hearing living knowledge. It connects directly to the people who once camped on these shores.

Another discovery came in the early 2000s. A young Mutthi Mutthi woman noticed footprints pressed into an old clay surface. Researchers found hundreds of them. They show adults, children and at least one person who seems to have hopped on one leg. The prints are thought to be around twenty thousand years old. They are among the largest collections of Ice Age human footprints known anywhere. For their protection, the site is covered and not open to visitors.

The Willandra Lakes Region was added to the World Heritage List in 1981. It was recognised for both natural and cultural values. That double listing is unusual. It reflects what makes this place special. Here you can read a long record of climate change in the layers of the dunes. In the same layers, you can see how people adapted to it, generation after generation, over tens of thousands of years.

There is also a more recent layer of history. Near the visitor area stands an old woolshed from the pastoral era of the late nineteenth century. It is built from rough timber posts, with a weathered, silver-grey frame. Thousands of sheep were once shorn here. Grazing changed this landscape deeply. Hooves and hungry animals stripped vegetation from the dunes, and that sped up the erosion. It is a quiet reminder that this land is always changing.

Now take a slow look around you. Notice the colours shift as the sun moves across the lunette — white, then cream, then rust and pink. Watch for emus crossing the flat ground, or red kangaroos resting in the thin shade of a bluebush. If you are here near sunset, the walls glow, and the sky above them becomes enormous. After dark, with almost no city lights nearby, the stars appear in their thousands.

As you walk back, think about the ground under your feet. Somewhere below this pale sand are fireplaces, tools and footprints from forty thousand years of family life. People fished here, cooked here and buried their loved ones here. The lake is gone, but the shoreline is still visible, if you know how to look. Take one more breath of the dry, clean air... and listen again to the wind moving across the old lake bed.
