History Of Morro Rock And The Nine Sisters


The nine sisters are extinct volcano peaks which run in an approximately straight line for twelve miles, stretching from Morro Bay to San Luis Obispo. These peaks seperate the Los Osos and Chorro Valleys. The peaks are approximately 21 million years old. Davidson Seamount, disregarded as part of the chain, is submerged about 2 1/2 miles offshore of Morro Rock.

This area was the original home of the Chumash Indians, who made camps at the base of these peaks and ate the berries and roots found growing in the mountain sides. There is currently an effort being made to have the peaks named as historical landmarks, and thus preserved from further development.

Elevation 576 feet. It is also called "the Gibralter of the Pacific" and is probably the most famous peak. It was first sighted in 1542 by Juan Cabrillo. At one time it was surrounded by water. Quarrying was responsible for its shape, and rock from it supplied the breakwater for Morro Bay. It is now protected home for the endangered Peregrine Falcon.

Elevation 665 feet. This hill is located in Morro Bay State Park. It provides an overlook to the city of Morro Bay.

Elevation 911 feet. Named after Juan CAbrillo, it is located within the section of Morro Bay State Park bordered by Turri Road, South Bay Blvd., and Chorro Creek.

Elevation 1,404 feet. Named after the family that lived at its base in 1884. This is the only peak which has a spring located at the base. It is the most majestic looking, and had religious significance to the Chumash Indians.

Elevation 1,306 feet. Named after the Chumash Indian Romauldo, who received a land grant for the property. It was a quarry site. Cuesta College lies between this peak and Hollister Peak.

Elevation 1,257 feet. Named by Louisiana Clayton Dart in 1964 in honor of the Chumash Indians. Quarrying recently took place at this peak for rock to be used in foundations of the new buildings at Cuesta College.

Elevation 1,559 feet. It was named for a Bishop's miter. This is the highest peak in the chain; its quarries were the source of rock for foundations, curbing and buildings in San Luis Obispo.

Elevation 1,2929 feet. This peak is privately owned by Alex Madonna of Madonna Inn. It was named in honor of Mission San Luis Obispo.

Elevation 777 feet. Located near the country airport, it is a round grassy hill. Most of the area around it has been developed.
