Abstract
This paper reports new dates for mid to late Holocene occupation of the lower Adelaide River in northern Australia. Earth mounds located on the margins of the floodplains provide a series of radiocarbon determinations that suggest continuous settlement from at least 4000 years BP until recently. During that time the floodplains have undergone a dramatic environmental evolution from extensive mangrove swamps in the mid Holocene, through a variable mosaic of estuarine and freshwater conditions c.3000 years ago, to the freshwater floodplains extant since 2000 BP. These results have implications for the chronology of earth mounds elsewhere in northern Australia.
