New dates for earth mounds at Weipa, North Queensland, Australia

Abstract

ABSTRACTThis paper reports new radiocarbon determinations for late Holocene occupation in the Weipa region of Far North Queensland, Australia. Earth mounds along the margins of small wetlands and freshwater creeks developed mainly after 2200 years ago, but are concentrated within the past 500 years. Their establishment appears to be associated with changing environmental conditions and a regional increase in the availability of permanent water sources around 2200 and 500 years ago. These results have implications for earth mound chronology and possibly climate change understanding elsewhere in Northern Australia.
