We dated a sacred Aboriginal women's site used for birthing ceremonies and discovered 7,000 years' worth of tool making

Investigation of a sacred area at Avon Downs in Jangga Country, Central Queensland, has uncovered evidence of stone tool production in a place that was traditionally restricted to women.

We detail our findings in newly published research in collaboration with archaeological expert Liz Hatte and Jangga Elders Colin McLennan and Marie Wallace.

Our excavation of the layered sediments at Avon Downs reveals a long history of raw stone extraction and tool making. In the short period of our study, we recorded about 1,500 stone artifacts on the surface and under the ground.

And this is just the tip of the iceberg, as we expect more detailed evidence of tool production to be found beneath the site's surface and in neighboring areas.

By dating these artifacts, we have traced a 7,000-year history of continuous stone tool production by Aboriginal women—including objects traditionally associated with men. We are also the first team to ever date a sacred Aboriginal women's area.

Hundreds of generations of tool making

Using a technique called optically stimulated luminescence, we measured the age of individual sand grains within the artifact-rich layers of the hill slope. We were then able to date the artifacts by association.

The uncovered artifacts varied in age from about 430 years ago (before the first Europeans arrived) to some 7,000 years ago. This implies the site was used for stone tool production and possibly as a sacred women's area for hundreds of generations.

Jangga Elders Colin McLennan and Marie Wallace have a shared memory extending as far back as at least six generations. They understand the site has always been forbidden to men, as it continues to be today.

While some of the relevant sacred knowledge remains restricted, we can report that Jangga women came to Gaio Nanhi Bura (women's sacred place) to give birth and perform associated ceremonies until the turn of the 20th century.

Some of the stone tools were used in sacred ways, such as for cutting the umbilical cord of newborn babies, says Wallace. Drill points, ochre and a grinding stone and muller are further evidence of everyday tool making and decoration.

The rare discovery of an unfinished axe, ready to be ground and polished, is also somewhat surprising, as axe-making is typically associated with male crafters.

The site remains a direct link between modern Jangga women and their ancestors. Today's Jangga women who have visited and worked on the site describe feeling a strong sense of peace and belonging, as well as the presence of their ancestors.

Railway project disruptions

Like many other Aboriginal sites in Australia, the Avon Downs Women's Area has faced threats. It sits in the way of the North Galilee Basin Rail Project, which stretches from the Carmichael coal mine to the port at Abbot Point.

Planning for this project started in 2012, prompting cultural heritage surveys, assessments and negotiations with Traditional Owners.

In 2014, the sacred area at Avon Downs was revealed following a survey and consultations with Jangga Elders. The artifacts themselves, which had been partially hidden by thick spinifex grass, were discovered in 2020 during cultural heritage monitoring before the clearance of native forest.

After extended negotiations with the Carmichael project representatives, and some news coverage of the archaeological discoveries, a solution was found.

For the benefit of future study, the site was conserved as a protected portion inside the rail corridor—but not without any loss. This portion is a fragmented piece of a much larger complex of camp sites and knapping floors (areas where stone tools were shaped)—but there is no longer free access between these individual sites.

So while the railway project will not run directly through, it has still compromised the integrity of the area.
