Crooked River Light
The Crooked River Light, also known as the Carrabelle Light, was built in 1895 to replace the Dog Island Light on Dog Island, which had been destroyed in 1875 by a hurricane. The location on the mainland allowed the light to serve as the rear range light for the channel to the west of Dog Island, used by ships in the lumber trade. History The Crooked River Lighthouse, built in 1895, replaced three lighthouses on Dog Island that over the years were destroyed by storms. The lightstation grounds originally included a house for both the Keeper and the Assistant Keeper, and several outbuildings. At first the lighthouse was painted solid dark red except for the black lantern room. Later (at the end of 1901) the lower half was painted white to offset it from the surrounding pine forest. This is the same daymark seen on the lighthouse today - the lower half white, the upper half red and a black lantern room. After being electrified in 1933, the lighthouse was automated and unmanned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog Island Light
Several lighthouses called Dog Island Light were constructed on the western tip of Dog Island south of Carrabelle, Florida. They marked the "middle entrance to St. George's Sound," between St. George and Dog Islands, during the nineteenth century, until its collapse by a hurricane in 1873. History The first lighthouse, a brick tower, was completed in 1839. A storm in 1842 destroyed the keeper's house and badly damaged the lighthouse tower. A wooden tower was completed in 1843 to replace the brick tower. This second tower was destroyed by a hurricane in 1851. A brick tower was built in 1851. This is the lighthouse in the photo above. The obsolete lamp and reflector system in the light was replaced by a Forward drop lens in 1856, which was more efficient. During the Civil War, Confederate forces burned the stairs in the tower and damaged the lens to prevent the tower from being used as a lighthouse or a watchtower. The light was repaired and put back into service after the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog Island, Florida
Dog Island is located in the northwestern Florida Gulf coast, just off-shore from Carrabelle, in Franklin County, Florida. There is, by reservation, ferry transportation to Dog Island on weekends.

Range Light
Leading lights (also known as range lights in the United States) are a pair of light beacons used in navigation to indicate a safe passage for vessels entering a shallow or dangerous channel; they may also be used for position fixing. At night, the lights are a form of leading line that can be used for safe navigation. The beacons consist of two lights that are separated in distance and elevation, so that when they are aligned, with one above the other, they provide a bearing. Range lights are often illuminated day and night. In some cases the two beacons are unlighted, in which case they are known as a range in the United States or a transit in the UK. The beacons may be artificial or natural. Operation Two lights are positioned near one another. One, called the front light, is lower than the one behind, which is called the rear light. At night when viewed from a ship, the two lights only become aligned vertically when a vessel is positioned on the correct bearing. During t ...

Lumber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

List Of Lighthouses In Florida
This is a list of existing and past lighthouses in the state of Florida in the United States. See also *Unmanned reef lights of the Florida Keys *List of lighthouses in the United States *List of lighthouses in the United States by height *Maritime history of Florida Notes :A. The first tower was built around 1737. Archival records are inconclusive as to whether the Spanish used the tower as a lighthouse. While it seems likely, not enough has been gathered to place it as a fact. :B. The tower was washed away in 1851. :C. In 1960, the lighthouse was replaced with a skeletal steel tower. The old structure moved multiple times as a private residence before it was returned to St. Joseph Bay in 1979. While the old light remains a private residence, its current owner has restored its former appearance with a rebuilt lantern room.

List Of Lighthouses In The United States
This is a list of lighthouses in the United States. The United States has had approximately a thousand lights as well as light towers, range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Lighthouses that are in former U.S. territories are not listed here. Most of the lights in the United States have been built and maintained by the Coast Guard (since 1939) and its predecessors, the United States Lighthouse Service (1910–1939) and the United States Lighthouse Board (1852–1910). Before the Lighthouse Board was established, local collectors of customs were responsible for lighthouses under Stephen Pleasonton. As their importance to navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership and in some cases responsibility for running them to other parties, the chief of them being the National Park Service under the National Historic Lighthouse Preservation ...

Lighthouses Completed In 1895
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
