A 38,000‐year‐old archaeological site at Upper Swan, Western Australia

Abstract
An extensive open‐air site, on an ancient floodplain bordering the Swan River, has been partially uncovered by a clay pit operation. Preliminary excavations of small areas have yielded stone artefacts intimately associated with charcoal and carbonized material, possibly resin. A series of radiocarbon measurements place the site among the earliest yet known from Australia, and indicate that the southwestern corner of the continent was populated by about 40,000 years ago.
