Deepwater Shoals Light
The Deepwater Shoals Light was a lighthouse located in the James River upstream from Newport News, Virginia. History This light was erected in 1855 to mark the western edge of the channel. Ice damaged the light in the following year, and again in 1867; in the latter case the light had to be rebuilt completely, at which time the light was upgraded to a sixth-order Fresnel from the previous masthead light. During the Civil War the light was extinguished by confederate forces; relit in 1862, the Lighthouse Board reconsidered and removed the lighting apparatus to Fort Monroe for safekeeping. Decommissioning came in 1936, and the house was torn down in 1966. A steel tower light has been erected on the old iron foundation.

National Hydrography Dataset high-resolution flowline dataThe National Map , accessed April 1, 2011 to Chesapeake Bay. The river length extends to if one includes the Jackson River, the longer of its two source tributaries. It is the longest river in Virginia. Jamestown and Williamsburg, Virginia's first colonial capitals, and Richmond, Virginia's current capital, lie on the James River. History The Native Americans who populated the area east of the Fall Line in the late 16th and early 17th centuries called the James River the Powhatan River, named for the chief of the Powhatan Confederacy which extended over most of the Tidewater region of Virginia. The Jamestown colonists who arrived in 1607 named it "James" after King James I of England (), as they constructed the first permanent English settlement in the Americas at Jamestown along th ...

Newport News, Virginia
Newport News () is an independent city in the U.S. state of Virginia. At the 2020 census, the population was 186,247. Located in the Hampton Roads region, it is the 5th most populous city in Virginia and 140th most populous city in the United States. Newport News is included in the Hampton Roads metropolitan area. It is at the southeastern end of the Virginia Peninsula, on the northern shore of the James River extending southeast from Skiffe's Creek along many miles of waterfront to the river's mouth at Newport News Point on the harbor of Hampton Roads. The area now known as Newport News was once a part of Warwick County. Warwick County was one of the eight original shires of Virginia, formed by the House of Burgesses in the British Colony of Virginia by order of King Charles I in 1634. In 1881, fifteen years of rapid development began under the leadership of Collis P. Huntington, whose new Peninsula Extension of the Chesapeake and Ohio Railway from Richmond opene ...

Cast-iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

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] |
Lighthouse
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Fort Monroe
Fort Monroe, managed by partnership between the Fort Monroe Authority for the Commonwealth of Virginia, the National Park Service as the Fort Monroe National Monument, and the City of Hampton, is a former military installation in Hampton, Virginia, at Old Point Comfort, the southern tip of the Virginia Peninsula, United States. Along with Fort Wool, Fort Monroe originally guarded the navigation channel between the Chesapeake Bay and Hampton Roads—the natural roadstead at the confluence of the Elizabeth, the Nansemond and the James rivers. Union General George B. McClellan landed his forces at the fort during Peninsula campaign of 1862 during the American Civil War. Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Lighthouse Society
The United States Lighthouse Society is a non-profit organization dedicated to aiding in the restoration of American lighthouses and educating the public about their history. With four chapters, and more than a dozen affiliates, it is one of the largest and oldest lighthouse organizations in the world. History Founded in 1984 by Wayne Wheeler and initially headquartered in San Francisco, California, one of the United States Lighthouse Society's first major projects was the purchase of the lightship LV605 in 1986 from a private individual. The organization subsequently invested $400,000 and more than 40,000 volunteer hours in the preservation and restoration of the vessel. In 2003 the society received the California Governor's Historic Preservation Award for its work on the ship. The society relocated from California to Hansville, Washington in 2008, siting its headquarters at the historic Point No Point Lighthouse, which it rented from Kitsap County (the county, in turn, lease ...
