New archaeological evidence from Dargan Shelter in the Blue Mountains reveals high-altitude occupation in Australia over 20,000 years ago, challenging long-held beliefs about Ice Age settlement limits. The discovery of 693 artefacts and hearths highlights deep cultural ties and sustained Aboriginal presence in the high country during extreme climatic conditions.
A recent archaeological finding in the Blue Mountains pushed back the timeline of inhabitation in the high elevation of Australia by a few thousand years. The team of archaeologists unearthed 693 artifacts and multiple hearths at the ancient cave Dargan Shelter dating back to 20,000 years ago.
This discovery proves the high mountains of Australia were occupied during the last stage of Ice Age, defying the earlier research about oldest occupation in the continent restricting itself to elevations at or below the periglacial zone. It also puts Australia on the map with other countries showing cold temperatures did not limit the movement to the high altitudes or their continued occupation.
Dargan Shelter is an ancient rock shelter in Dharug Country along the Blue Mountains. It holds strong cultural connections with many Aboriginal groups who have inhabited the mountain for thousands of years. The rock art indicates the use of the cave as a meeting place and for cultural and spiritual ceremonies.
The stone artefacts prove that the site was occupied and not served as a mere stopover. The evidence suggests the tools were made from local stones while some were imported from far-away regions like Jenolan and Hunter. The scholars believe it indicates occasional movement of people to the mountains or their participation in the trade and ceremonial activities of the region.
This discovery revises the existing research that Australian mountains were too difficult for occupation due to their extreme cold climate and high altitudes. The local custodians of the region hope the research will protect their cultural heritage for the future generations.
