Isle La Motte Light
The Isle La Motte Light in Vermont is an iron lighthouse at the northern end of Isle La Motte in Lake Champlain. It is one of several lights on the lake which were reactivated in their original structures early in the 21st century. History This light, together with the Windmill Point Light, forms something of a range marking the center of the channel in this section of the lake. A light was placed here as early as 1829; some sources state it was initially a lantern simply hung in a tree, but all agree that it was soon hung in an upper story window of a stone house (still standing today). In 1856 the Lighthouse Board purchased a small plot and erected a stone pyramid on it, with a lantern placed at its peak. This light was first lit in 1857 and was tended by a local farmer rather than by a dedicated keeper. The farmer lived at some distance from the light, and there were constant problems with the lamp being extinguished on stormy nights. After requests through the first part of ...

Isle La Motte
Isle La Motte is an island in Lake Champlain in northwestern Vermont, United States. At 7 mi (11 km) by 2 mi (3 km), it lies close to the place that the lake empties into the Richelieu River. It is incorporated as a New England town in Grand Isle County. Its population was 488 at the 2020 census. The island is named after a French soldier, Pierre La Motte, who built a military outpost on the island in 1666. The island's population significantly increases in the summer months. The island is the site of Fort Sainte Anne, Saint Anne's Shrine, the Methodist Episcopal Church of Isle La Motte, the Fisk Quarry and Goodsell Ridge Preserves, the Isle La Motte Elementary School, and the Isle La Motte Lighthouse. History On 9 July 1609, Samuel de Champlain debarked on the island. In 1665, the French began building a series of forts along the Richelieu River to protect New France from the Iroquois. From north to south these were Fort Richelieu, Fort Chambly, and Fort Sainte Thé ... [...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.

Vermont
Vermont () is a state in the northeast New England region of the United States. Vermont is bordered by the states of Massachusetts to the south, New Hampshire to the east, and New York to the west, and the Canadian province of Quebec to the north. Admitted to the union in 1791 as the 14th state, it is the only state in New England not bordered by the Atlantic Ocean. According to the 2020 U.S. census, the state has a population of 643,503, ranking it the second least-populated in the U.S. after Wyoming. It is also the nation's sixth-smallest state in area. The state's capital Montpelier is the least-populous state capital in the U.S., while its most-populous city, Burlington, is the least-populous to be a state's largest. For some 12,000 years, indigenous peoples have inhabited this area. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, Fr ...

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] |
Windmill Point Light (Vermont)
The Windmill Point Light in Vermont is the northernmost lighthouse on Lake Champlain. Extinguished for seventy years, it was reactivated in 2002 to replace the skeleton tower erected next to it. It is named after the Windmill Point peninsula, where it is located. History The first lighthouse on this site was privately erected in 1830. In 1858, the Lighthouse Service contracted with the Ellis and O'Neil firm to erect the present octagonal tower, which is connected directly to the keeper's house. Together with the Isle La Motte Light, it forms a rough line marking the channel through the center of the lake. It remained in service until 1931, when a steel tower was erected on the property with an automated acetylene light on top. The keeper's house was transferred to the customs service for use in battling smuggling during Prohibition. The tower and house were eventually sold to a private individual. In 1963 the light was purchased by Lockwood Clark, who had come across the then- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Buildings And Structures In Isle La Motte, Vermont
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the :Human habitats, human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful).
