This postcard with Pigeon Point Lighthouse (Pescadero, California) arrived from Ruth. This lighthouse was built in 1871 and is the second tallest on the West Coast (115 foot). |
Wiki says:
Pigeon Point Light Station or Pigeon Point Lighthouse is a lighthouse built in 1871 to guide ships on the Pacific coast of California. It is the tallest lighthouse (tied with Point Arena Light) on the West Coast of the United States. It is still an active Coast Guard aid to navigation. Pigeon Point Light Station is located on the coastal highway (State Route 1), 5 miles (8 km) south of Pescadero, California. The 115-foot (35 m), white masonry tower, resembles the typical New England structure.
Pigeon Point Lighthouse is one of the most picturesque lighthouses on the Pacific coast. The tower stands on a rocky promontory and has long been a landmark for ships approaching San Francisco Bay from the south. This headland, and hence the lighthouse, took its name from the ship Carrier Pigeon that wrecked here in 1853.
The lantern room of the tower is equipped with the original first-order, 1000-watt Fresnel lens. Illuminated for demonstration purposes only today, the lens has 24 flash panels, is composed of 1008 hand-polished lenses and prisms and is capable of producing over 500,000 candlepower illumination. It was manufactured by the Henry-LePaute company in Paris, France and was first lit at Pigeon Point at sunset on November 15, 1872.
Originally the tower was equipped with a lamp that burned refined lard oil. In 1888, that lamp was replaced with a mineral oil (kerosene) lamp. To produce Pigeon Point's assigned characteristic of one white flash of light every ten seconds, the four ton lens rotated one time every four minutes. When observed from a distance, this resulted in the appearance of one white flash of light every ten seconds. The lens rotation was originally powered by a clockworks and weight. In 1926 the lighthouse was provided with electricity.
The lighthouse has been designated California Historical Landmark number 930. In 1972, the United States Coast Guard mounted a 24-inch aerobeacon on the front of the tower and officially retired the Fresnel lens from regular duty. The Fresnel lens is now lit only to celebrate special occasions, such as the annual lighting of the lens, which usually occurs in mid-November (closest Saturday to Nov. 15) the date of the original first lighting in 1872. The light (outside aerobeacon) is still an active aid to navigation.
