Revisiting the Santa Barbara Museum of Natural History 1935 Hurricane Deck Expedition

When informed of artifact-rich caves and spectacular paintings in the backcountry, the Santa Barbara Museum of Natural History mounted a research expedition in 1935 to survey and document the sites, as well as to rescue the artifacts that were being systematically looted from the many cache caves in the area. Time intervened, and the results of the expedition were never published as originally intended. The current study takes a small step toward realizing some of the goals of the 1935 project.

After 85 years of continued interest in Chumash rock art and archaeology, new methods and insights facilitate a fresh look at the region, its rock art, and its largely overlooked archaeological record. This presentation focuses on the role of women in rock art production, the role of rock art sites and medicine, and possible depictions of the Milky Way and its importance to the annual harvest rituals of the Chumash.

Bill Hyder retired from the University of California Santa Cruz in 2010 after thirty years of academic and information technology management. He earned MAs in political science and anthropology. His interest in rock art began in 1970 after reading Campbell Grant’s Rock Paintings of the Chumash. As an independent researcher, he conducted studies for the California State Parks and the National Park Service. Bill is a past president of the American Rock Art Research Association and a Research Associate with the Santa Barbara Museum of Natural History Anthropology Department, and he currently serves on the board of the California Rock Art Foundation. His retirement years have been devoted to research, writing, and designing and producing publications covering prehistoric art and his other passion, numismatics.
