13 ARCHAEOLOGICAL EVIDENCE OF HOLOCENE SUBMERGENCE ALONG THE OREGON AND SOUTHERN WASHINGTON COAST Rick Minor Heritage Research Associates, Inc.

1997 Garden Avenue Eugene, Oregon 97403 Evidence from archaeological sites along the Oregon and southern Washington coast has the potential to contribute to the study of Holocene earthquakes and subduction in the Pacific Northwest. Although the antiquity of human occupation (as demonstrated by radiocarbon dating) has been pushed back to circa 8000 B P, the great majority of the archaeological sites so far investigated in this coastal region were occupied within the last 3000 years. A significant change in sea level is reflected in the archaeological record around 3000 BP; this change apparently coincided with the formation of extensive dune systems at this time.

Continuing relative rise in sea level is indicated in the occurrence of anhaeological sites with submerged cultural deposits occupied in late prehistoric and early historic times. Available archaeological evidence shows that submergence has occurred along the Oregon and southern Washington coast in the late Holocene.
