The Chumash are a Native American people who historically inhabited the central and southern coastal regions of California, in portions of what is now San Luis Obispo, Santa Barbara, Ventura and Los Angeles Counties, extending from Morro Bay in the north to Malibu in the south. They also occupied three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited on a seasonal basis due to the lack of a consistent water source. Modern place names with Chumash origins include Cayucos, Malibu, Lompoc, Ojai, Pismo Beach, Point Mugu, Port Hueneme, Piru, Lake Castaic, Saticoy, and Simi Valley.
