The Nine Sisters
The Nine Sisters or the Morros are a chain of nine volcanic peaks and hills between Morro Bay and San Luis Obispo, California. They are popular with photographers and rock climbers. Their volcanic origin makes them of significant geological interest. They support a wide variety of plant, animal, and bird life. Two of the peaks are in Morro Bay State Park.
The peaks were created over 20,000,000 years ago as volcanic plugs of magma which welled up and solidified inside softer rock which has since been eroded. The highest peak is Bishop Peak at 1,559 feet (475 m).
