The archaeology of submerged prehistoric sites on the North Pacific Coast of North America

Abstract

We review the history of underwater archaeological investigations of submerged prehistoric remains on the North Pacific Coast of North America, divided into three phases: Phase 1 (1960s–1981) – hypotheses and “wet-site archaeology”; Phase 2 (1981–1994) – operationalized scuba explorations of submerged anchor stone accumulations and the Montague Harbour Underwater Archaeology Project; and Phase 3 (1995–present) – refined modeling of regional sea beds for areas of high archaeological potential on submerged relict shorelines with limited testing and identification of late Pleistocene and early Holocene archaeological deposits on near-shore intertidal and interior upland strandlines. The latter part of Phase 3 also saw the potential for submerged prehistoric cultural resources integrated into consideration of development project assessments. Finally, the Coastal Migration Route for early migration to the Americas shifted from a peripheral proposition to a central complimentary paradigm. These multiple streams of theory, modeling, and pragmatic effort are poised to converge in a new era of practical underwater archaeological research on the North Pacific Coast.
