Geoarchaeological investigations of repeated site occupation in the uplands of the Portland Basin

Archaeological deposits discovered at three sites near Vancouver, Washington, challenge the accepted view of the depositional history of the Portland Basin since the late Pleistocene. Deep, intact archaeological features and deposits dating to as early as ca. 8,000 cal yr BP were discovered during archaeological excavations and construction monitoring. The archaeological and stratigraphic records found at the sites suggest that sediment accumulation in some upland areas of the region did not cease after the deposition of late Pleistocene catastrophic flood sediments, but continued well into the Holocene in the form of eolian deposition. Geoarchaeological techniques were used at the sites to reconstruct their history since the late Pleistocene and to better understand the depositional and environmental history of the sites' vicinity.
