Regarding Morro Rock.

• In 1542, Juan Rodriguez Cabrillo, the Portugese explorer, sighted and named Morro Rock.
• In 1769, Gaspar de Portola, Father Juan Crespi, and some sixty other men and one hundred mules marched north on an overland expedition from San Diego, to find Monterey Bay, camping at one point near Morro Rock.
• The Rock was quarried periodically from 1889 to 1963. In 1966 the State of California obtained title to it, and in 1968 was declared a state landmark, and Morro Rock is now a nature preserve.
