Granite Island Lighthouse
Because it was positioned near the busy shipping lanes of the mid-19th century, a lighthouse was built on Granite Island in 1868 by the U.S. Lighthouse Board and commissioned in 1869. The lighthouse keeper's dwelling and the square tower attached to it are built of cut stone with white limestone decorations on the corners and windows. The 1-story dwelling shares its design with lighthouses found on Gull Rock and Huron Islands Lighthouse as well as the Marquette Harbor Light. There is an existing Fog Signal Building, which was constructed in 1910 to replace the one originally built in 1879. It is made of structural steel and is a bell tower. The fog bell was the one from the light at Thunder Bay Island Light, and was removed. in 1939. Lighthouse keepers and assistant keepers operated Granite Island Light until 1937 when the facility was automated and the living quarters were abandoned. Aids to navigation consisted of a 4th order Fresnel lens and a fog bell tower. The focal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navigation
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Completed In 1868
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] |
Detroit News
''The Detroit News'' is one of the two major newspapers in the U.S. city of Detroit, Michigan. The paper began in 1873, when it rented space in the rival ''Detroit Free Press'' building.

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 ...

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 ...

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] |

Mackinac Center For Public Policy
The Mackinac Center for Public Policy () in Midland, Michigan, is the largest U.S. state-based free market think tank in the United States. The Mackinac Center conducts policy research and educational programs. The Center sponsors MichiganVotes.org, an online legislative voting record database which provides a non-partisan summary of every bill and vote in the Michigan legislature. Mackinac Center scholars generally recommend lower taxes, reduced regulatory authority for state agencies, right-to-work laws, school choice, and enhanced protection of individual property rights; they avoid socially conservative issues such as reproductive or marriage rights. Joseph P. Overton, (1960–2003), a senior vice president of the Mackinac Center, stated the political strategy that later became known as the Overton window. Overton said that politically unpopular, unacceptable policies must be changed into politically acceptable policies before they can be enacted into law. The Center was ran ...
