Rick L OGY OF L alifornia’s northern Channel Islands have one of the longest and best preserved archaeological records in the Americas, spanning some 13,000 calendar years. When CEuropean explorers first traveled to the area, these islands were inhabited by the Chumash, some of the most populous and culturally complex hunter-gatherers known. ate Chumash society was characterized by hereditary leaders, sophisticated exchange networks and HO interaction spheres, and diverse maritime economies. Focusing on the archaeology of five sites Perspectives in California Archaeology, Volume 8 dated to the last 3,000 years, this book examines the archaeology and historical ecology of San L O Series Editor: Jeanne E. Arnold Miguel Island, the westernmost and most isolated of the northern Channel Islands. Detailed CE faunal, artifact, and other data are woven together in a diachronic analysis that investigates the N interplay of social and ecological developments on this unique island. The first to focus solely on E Cotsen Institute of Archaeology S San Miguel Island archaeology, this book investigates issues ranging from coastal adaptations to A University of California, Los Angeles emergent cultural complexity to historical ecology and human impacts on ancient environments. N M I “This is an exceptionally fine piece of research ... It is well written, well researched, and presents G UEL important findings from a fascinating but under-researched corner of the Chumash archaeology world. It definitely represents a major contribution to California archaeology and prehistory.” I SLA — Terry L. Jones, California Polytechnic State University, San Luis Obispo ND R Torben C. Rick received his Ph.D. in Anthropology from the University of Oregon. Currently Assistant Professor of Anthropology at Southern Methodist University, he has published widely on the archaeology and historical ecology of maritime hunter-gatherers. With research interests in coastal and maritime societies, social and economic complexity, and zooarchaeology, he has worked on the Channel Islands, southern California coast, and Pacific Northwest.

RICK COTSEN INSTITUTE OF ARCHAEOLOGY UNIVERSITY OF CALIFORNIA, LOS ANGELES 2007 THE COTSEN INSTITUTE OF ARCHAEOLOGY at UCLA is a research unit at the University of California, Los Angeles that promotes the comprehensive and inter-disciplinary study of the human past. Established in 1973, the Cotsen Institute is a unique resource that provides an opportunity for faculty, staff, graduate students, research associates, volunteers and the general public to gather together in their explorations of ancient human societies. Former President and CEO of Neutrogena Corporation Lloyd E. Cotsen has been associated with UCLA for more than 30 years as a volunteer and donor and maintains a special interest in archaeology. Lloyd E. Cotsen has been an advisor and supporter of the Institute since 1980. In 1999, The UCLA Institute of Archaeology changed its name to the Cotsen Institute of Archaeology at UCLA to honor the longtime support of Lloyd E. Cotsen. Cotsen Institute Publications specializes in producing high-quality data monographs in several different series, including Monumenta Archaeologica, Monographs, and Perspectives in California Archaeology, as well as innovative ideas in the Cotsen Advanced Seminar Series and the Ideas, Debates and Perspectives Series. Through the generosity of Lloyd E. Cotsen, our publications are subsidized, producing superb volumes at an affordable price.
