REASSESSING HUMAN SETTLEMENT ON THE SOUTH COAST OF SAN MIGUEL ISLAND, CALIFORNIA: THE USE OF 14C DATING AS A RECONNAISSANCE TOOL
Abstract
Californias San Miguel Island contains over 600 archaeological sites, some occupied as early as 12,000 yr ago
and most located along the islands north coast. Archaeologists have long believed the south coast to have been marginal or
largely uninhabited. Burial of some landforms by sand dunes deposited after historical overgrazing, the lack of systematic survey,
and a dearth of radiocarbon dating have also contributed to an underestimation of the intensity of human land use along
the south coast of San Miguel Island. Our recent reconnaissance and dating of shell middens on the islands south coast indicate
more intensive occupation than previously thought, with numerous south coast sites spanning at least the past 9000 yr,
and demonstrate the utility of combining systematic archaeological reconnaissance and radiometrics in reconstructions of
human settlement and historical ecology in coastal environments.
