Pigeon Point Lighthouse

Pigeon Point Lighthouse, located south of San Francisco, was first lit in 1872 and is the tallest lighthouse on the west coast. The current set of images focuses on its massive lens, which stands 16 feet tall and is 6 feet in diameter. This first-order Fresnel lens is comprised of 1008 prisms. The "lighthouse keeper" checking the state of the bulbs is Peter, a docent for the Pigeon Point Light Station State Historic Park, wearing a historic lighthouse keeper uniform.
