California's Northern Channel Islands have produced several Paleocoastal assemblages that include some of the most intricate and finely crafted lithic technologies in the Americas. Current understanding of chert use and availability on the islands comes primarily from research on Late Holocene sites from Santa Cruz Island, where chert sources played an important role in providing microdrills for Late Holocene Olivella bead production. New data from Terminal Pleistocene and Early Holocene sites suggest that Paleocoastal peoples relied heavily on other cherts from San Miguel and Santa Rosa islands. To examine the deeper history of lithic use on the islands, we analyzed eight Paleocoastal lithic assemblages from San Miguel and Santa Rosa, which were part of the larger island of Santarosae until about 10,000 years ago. We discuss lithic availability and material preference for formal and expedient stone tool manufacture on the Northern Channel Islands between similar to 12,000 and 7,500 years ago.
