Thunder Bay Island Light
Thunder Bay Island Light, located on Thunder Bay Island's southeast tip, is one of the oldest operating lighthouses in Michigan. The third operating U.S. lighthouse in Lake Huron was built here in 1831, but it disintegrated almost at once and was rebuilt in 1832 of local limestone. This 1830s light tower was raised ) to a height of in 1857, and sheathed with brick. A fourth order Fresnel lens was installed. This 1857 light tower is the current Thunder Bay Island Light, although the tower has been further altered and is currently high. A fog bell was installed in 1858, and the lightkeeper's house was rebuilt in 1868. A steam-powered fog horn was added in 1871, and a fog signal building sheltering the fog signal apparatus was constructed in 1892. The lighthouse was staffed during the seasons of Great Lakes navigation from 1832 until the staff was replaced by automation in 1983, more than 150 years later. Current status The Thunder Bay Island Light was automated in 1983. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fog Horn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help mariner ...

Buildings And Structures In Alpena County, Michigan
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, 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 habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses On The National Register Of Historic Places In Michigan
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] |
Houses Completed In 1857
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouse Digest
''Lighthouse Digest'', a specialty magazine from FogHorn Publishing in East Machias, Maine, is about maritime history with particular attention to the preservation of lighthouses and their past. Though it is geared toward enthusiasts and antiquarians in the United States, it is also quoted commonly in more academic publications, and its editors have become a staple presence in scholarly circles. Editor Tim Harrison issued the first number in May, 1992. Scope Coverage includes historic and current lighthouse events and an events calendar for lighthouse activities around the United States and elsewhere. They publish a "Doomsday List" of Endangered lighthouses, and have helped save a number of at-risk lighthouses. They have been credited with uncovering many parts of lighthouse history that had been unknown, or which were thought to have been lost. Each issue carries articles and unusual lighthouse-related stories that, for the most part, cannot be found elsewhere, and many phot ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fog Bell
A fog bell is a navigation mark used as an audible aid to navigation in seafaring, especially in fog and poor visibility. Floating navigation signs with bells are called bell buoys. On ships, the ship's bell is used for sound signals. Due to more suitable sound generators, but also the development and spread of radar, satellite navigation and Electronic Chart Display and Information System, electronic charting systems, fog bells have lost their importance for maritime navigation. Maritime marks on land Starting in the 18th century, fog signals were given for seafaring in Europe, initially cannons or guns. In 1766, the first bell for this purpose was installed in Nidingen on the Baltic Sea.Thomas Tag''Fog Bells'' United States Lighthouse Society website. Retrieved September 27, 2021. These were initially rung by hand, which was a chore during prolonged fog, others used mechanisms similar to clockwork that had to be wound periodically.
