California Historical Landmarks in San Luis Obispo County
California Historical Landmark 821
An important mariner's navigational landfall for over three hundred years, Morro Reef was chronicled in the diaries of Portolá, Fr. Crespí, and Costanso in 1769, when they camped near this area on their trek to find Monterey. Sometimes called the 'Gibraltar of the Pacific,' it is the last in the famous chain of nine peaks which start in the city of San Luis Obispo.
