Advanced maritime technology associated with long-distance exchange and intensified resource acquisition has been linked to the development of stratification and greater sociopolitical complexity in the Pacific Rim region. One such example is the emergence of hereditary chiefs among the Chumash Indians of southern California. Plank boats owned by an elite group of wealthy individuals and chiefs were an integral part of an elaborate economic system that was based on maritime exchange. An artifact assemblage associated with the construction, maintenance, and use of this watercraft was identified and analyzed. It included wooden planks, asphaltum plugs, asphaltum caulking, and chipped stone drills. Radiocarbon dates and other relative-dating techniques provide strong evidence that the plank canoe originated at least 1,300 years ago in southern California. This represents the earliest use of this type of watercraft in North America and probably in the New World. The timing of this innovation provides evidence that sociopolitical complexity developed in the region at least 500 years earlier than previously proposed.
