Prehistory
Native American Chumash were the first inhabitants of the local area. These peoples relied partially on the harvesting of fish and shellfish (e.g. Macoma nasuta) from Morro Bay. There is a large Chumash archaeological site on a stabilized sand dune in Los Osos dating to at least as early as 1200 AD. Cabrillo first encountered the Chumash in the year 1542.
