Millys Cave: Evidence for Human Occupation of the Inland Pilbara during the Last Glacial Maximum

Abstract

The Last Glacial Maximum (LGM) peaked in Australia around 18,000 BP. At this time, many previously-occupied archaeological sites in the northwest quarter of the Australian continent show signs of abandonment or reduced occupation. Previously-reported evidence from the inland Pilbara on LGM activity is ambiguous and has been interpreted to mean both abandonment and continuous occupation. Excavations at Millys Cave have revealed the first unambiguous evidence for human occupation in the inland Pilbara during the LGM. Stone artefact data from Millys Cave indicate that the occupants exploited a smaller territorial area during the LGM compared with later periods, but did not substantially alter their land-use system. Population size probably changed very little but social networks and aggregation activities were reduced during the LGM. Show more
