Original Point Arena Fresnel Lens

The original Point Arena Lighthouse was built in 1870.  It had to be rebuilt after the 1906 earthquake in San Francisco.  After automation in 1977, the First-Order Fresnel lens was relocated to the current Visitor Center. The lens is 6 feet wide and has 666 hand-ground prisms. It has three sets of bulls-eyes that originally emitted a double flash every 6 seconds. The current value of this lens is over $3.5 million!

Richard and Pam lived in the San Francisco Bay Area 14 years (1987-1999 and 2008-2011). They lived in Florida 13 years previously, until returning in July 2011 to present. They hope their photography will encourage you to get out and discover nature's beauty in your own backyard, parks, and wild places.
