World's largest ice-age footprint site uncovered in Australia

At Australia's Willandra Lakes, TIME’s Lisa Clausen Visits the site of the world's largest repository of ice-age human footprints.

They were in the wrong place, but Steve Webb's archaeology class decided to stay anyway. A colleague had mistakenly taken them to a site they'd never visited before, a nondescript-looking claypan lost among the pale dunes in the Willandra Lakes region of far western New South Wales. Luckily, Webb thought it would still make good practice fieldwork for his Aboriginal students after a week of classes in the nearby town of Mildura. He was walking behind one of them, 26-year-old Mary Pappin Jr., when she called out that she'd seen something. What she'd spotted on the wind-blown surface looked like a footprint. "We'd all been walking over it," her mother Mary says proudly. "But that little one saw it."

What she'd chanced upon is still hard to believe - not only the first Ice Age fossilized human footprints found in Australia, but the largest collection ever found anywhere. "You just don't get this sort of archaeological signature," says Michael Westaway, executive officer of the Willandra Lakes World Heritage Area. "This is a story, really, for everybody." Today the prints look as sharp as if their makers had just hurried over the top of the nearest dune. "Almost as good as a footprint in wet sand," Webb says. Since the 2003 find, which was announced last December, his team has uncovered around 460 human prints crisscrossing the site like the traces of a peak-hour crowd, many deeply impressed in the sediment, clearly showing where mud once squished between toes. From their size and the distance between them, Webb and his team have formed a rough picture of 23 individuals who traversed what would have been a wet landscape between 19,000 and 23,000 years ago. A child wanders alone, a little way off from a group. Intersecting their paths is a one-legged man whose confident pace gives no clue as to how he propelled himself, and four tall men running fast, their heels skidding as they sped - were they hunters or prey?
