Alcatraz Island Lighthouse
Alcatraz Island Lighthouse is a lighthouse—the first one built on the U.S. West Coast—located on Alcatraz Island in California's San Francisco Bay. It is located at the southern end of the island near the entrance to the prison. The first light house on the island was completed in 1854, and served the bay during its time as a Citadel and military prison. It was replaced by a taller ( above mean sea level) concrete tower built in 1909 to the south of the original one which was demolished after it was damaged due to earthquake in 1906. The automation of the lighthouse with a modern beacon took place in 1963, the year Alcatraz closed as the Alcatraz Federal Penitentiary. It is the oldest light station on the island with a modern beacon and is part of the museum on the island. Although when viewed from afar it easily looks the tallest structure on Alcatraz, it is actually shorter than the Alcatraz Water Tower, but as it lies on higher ground it looks much taller.

Alcatraz Island
Alcatraz Island () is a small island about 1.25 miles offshore from San Francisco in San Francisco Bay, California, near the Golden Gate, Golden Gate Strait. The island was developed in the mid-19th century with facilities for a Alcatraz Island Lighthouse, lighthouse, a military fortification, and a military prison. In 1934, the island was converted into a federal prison, Alcatraz Federal Penitentiary. The strong tidal currents around the island and ice-cold water temperatures made escape nearly impossible, giving the prison one of the most notorious reputations of its kind in American history. The prison closed on March 21, 1963, leaving the island a major tourist attraction today. Beginning in November 1969, the island was Occupation of Alcatraz, occupied for more than 19 months by a group of Native Americans in the United States, Native Americans, initially primarily from San Francisco, who were later joined by the American Indian Movement and other urban Native Americans ...

Juan De Ayala
Juan Manuel de Ayala y Aranza (28 December 1745 – 30 December 1797) was a Spanish Navy officer who played a significant role in the European exploration of California, as he and the crew of his ship ''San Carlos'' were the first Europeans known to have entered the San Francisco Bay, having sailed there from the Port of San Blas, Nayarit, Mexico. Biography Ayala was born in Osuna, Andalucía, Spain. He entered the Spanish navy on 19 September 1760, and rose to achieve the rank of captain by 1782. He retired (on full pay on account of his achievements in California) on March 14, 1785. In the early 1770s, the Spanish royal authorities ordered an exploration of the north coast of California, "to Ascertain if there were any Russian Settlements on the Coast of California, and to Examine the Port of San Francisco". Don Fernando Rivera y Moncada had already marked the point for a mission in what is now San Francisco, and a land expedition to establish Spanish rule over the area ...

Cape St
A cape is a clothing accessory or a sleeveless outer garment of any length that hangs loosely and connects either at the neck or shoulders. They usually cover the back, shoulders, and arms. They come in a variety of styles and have been used throughout history for many different reasons. Semantic distinction In fashion, the word "cape" usually refers to a shorter garment and "cloak" to a full-length version of the different types of garment, though the two terms are sometimes used synonymously for full-length coverings. A shoulder cape is thus sometimes called a "capelet". The fashion cape does not cover the front to any appreciable degree. In raingear, a cape is usually a long and roomy protective garment worn to keep one dry in the rain. History The first known usage of capes is unknown, but some early references we know of are from Ancient Roman military uniforms. Later on, capes were common in medieval Europe, especially when combined with a hood in the chaperon. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Augustin Fresnel
Augustin-Jean Fresnel (10 May 1788 – 14 July 1827) was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Isaac Newton, Newton's corpuscular theory of light, corpuscular theory, from the late 1830s until the end of the 19th century. He is perhaps better known for inventing the Catadioptric system, catadioptric (reflective/refractive) Fresnel lens and for pioneering the use of "stepped" lenses to extend the visibility of lighthouses, saving countless lives at sea. The simpler Dioptrics, dioptric (purely refractive) stepped lens, first proposed by Georges-Louis Leclerc, Comte de Buffon, Count Buffon and independently reinvented by Fresnel, is used in screen magnifying glass, magnifiers and in condenser lenses for overhead projectors. By expressing Christiaan Huygens, Huygens's principle of secondary waves and Thomas Young (scientist), Young's principle of interference ...

Cape Disappointment Lighthouse
The Cape Disappointment Light is a lighthouse on Cape Disappointment near the mouth of the Columbia River in the U.S. state of Washington. History In 1848, it was recommended a lighthouse be located at Cape Disappointment in what was then the Oregon Territory. An appropriation of $53,000 was made in 1852. After the lighthouse was designed, a first-order Fresnel lens was ordered. When the lens arrived it was found to be too large for the tower. Rebuilding the tower took an additional two years. The first lighthouse in the Pacific Northwest was finally lit on October 15, 1856. In addition to the light, the station was equipped with a bell powered by a striking mechanism. The keeper's residence was about a quarter-mile away. The lighthouse had several shortcomings. The fog bell was sometimes inaudible due to the roar of ocean waves. It was discontinued in 1881 and moved to West Point Light in Seattle, and eventually to Warrior Rock Light near Portland. Also, the light was not ...

Humboldt Harbor Light
The Humboldt Harbor Light was an early lighthouse marking the entrance to Humboldt Bay. Plagued by fog, earthquakes, and flooding, it was eventually abandoned and left to deteriorate in favor of a new light at Table Bluff. History Humboldt Bay is reached through a narrow gap between two long sand spits, and the founding of Eureka, California in 1850 on the shores of the bay led to the provision of a lighthouse for the bay in the first set of eight west coast lights. The design was essentially that of the original Point Loma Light: a central tower with a 1½ story house erected around it. A fourth order Fresnel lens was provided and the light was first exhibited in December 1856. The protracted construction made this the last of the original eight lights to be completed, and in fact some lights in the next set were lit first. The light was situated in a sandy area towards the tip of the northern spit; the intent was for the light to serve both as a marker for the entrance and as ...

Farallon Island Light
Farallon Island Light is a lighthouse on Southeast Farallon Island, California. One of the highest lights in California, it was constructed in 1855 to warn ships approaching San Francisco from the west away from the rocky islands. In later years it was shorn of its lantern, but it remains in use. History Farallon Island Light was constructed on Southeast Farallon Island. After the tower was complete, it proved too small to house a first-order Fresnel lens, and the tower had to be torn down and rebuilt. The lighthouse was lit for the first time in December 1855. In 1939, the United States Coast Guard took over the lighthouse when the United States Lighthouse Service merged with it. The Coast Guard maintained a presence until 1972. By that time, the lantern room and the Fresnel lens had been removed, and an automated aero beacon was placed on the tower. The lens is on display in the San Francisco Maritime National Historic Park visitor center on Hyde Street, while the lantern ...
