San Clemente Island is a microcosm of California coastal archaeology from prehistoric through historic times-not only because of the extensiveness of its archaeological remains but because those remains have been so well preserved. In California Maritime Archaeology, the authors use the island as a platform to explore evidence of early seafaring, colonization, paleoenvironmental change, and cultural interaction along the California coast. They make a strong case that San Clemente island should be seen as a kind of California archaeological Galapagos, offering an extraordinary variety of ancient life as well as surprising information about prehistoric hunter-gatherers of the northern Pacific. The authors’ two decades of research have resulted in this rich cultural history that defies widespread assumptions about California’s ancient maritime history.
