Chipped Stone Crescents and the Antiquity of Maritime Settlement on San Nicolas Island, Alta California

Abstract Radiocarbon dates from archaeological sites on San Nicolas Island place the earliest human occupation at around 6000 cal BP The presence of chipped stone crescents, however, suggests that the island was first occupied during the early Holocene or terminal Pleistocene. In this article, we describe 18 crescents reportedly found on San Nicolas and discuss their significance as indicators of Paleo-Coastal occupation. These data suggest that in evaluating the antiquity and intensity of Paleo-Coastal settlement of California's Channel Islands, a combination of radiocarbon dates and temporally diagnostic technologies is required.
