DeTour Reef Light
The DeTour Reef Light is a non-profit-operated lighthouse marking the southern entrance of the DeTour Passage between the eastern end of Michigan's Upper Peninsula and Drummond Island. The light is an automated active aid to navigation. It marks the northern end of Lake Huron. The passage is used by almost all of the Great Lakes commercial freighter traffic moving to and from Lake Superior, with approximately 5,000 vessel movements annually. It is said to be "the gateway to Lake Superior." In addition, many recreational boaters use the passage. The Light is located in Lake Huron, three miles (5 km) south of the nearest town, DeTour Village, Michigan. Lighthouse history The southern entrance to DeTour Passage is made dangerous by a shoal, DeTour Reef. In order to enter or leave the passage, boats must thread past a shallow area no more than deep. In 1847 a lighthouse was located on shore at Point DeTour, Michigan to protect the DeTour Passage at the northwestern end of ...

Lake Huron
Lake Huron ( ) is one of the five Great Lakes of North America. Hydrology, Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as Lake Michigan, to which it is connected by the , Straits of Mackinac. It is shared on the north and east by the Canadian province of Ontario and on the south and west by the U.S. state of Michigan. The name of the lake is derived from early French explorers who named it for the Wyandot people, Huron people inhabiting the region. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of the lake include the North Channel (Ontario), North Channel and Georgian Bay. Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River (Michigan–Ontario), St. Marys River, and the main outlet is the St. Clair River. Geography By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of — ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Ship
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with crane (machine), cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. Definitions The words ''cargo'' and ''freight'' have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard the ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: # Liner business: typically (but not exclusively) container vessels (where ...

Argand Lamp
The Argand lamp is a type of oil lamp invented in 1780 by Aimé Argand. Its output is 6 to 10 candelas, brighter than that of earlier lamps. Its more complete combustion of the candle wick and oil than in other lamps required much less frequent trimming of the wick. In France, the lamp is called "Quinquet", after Antoine-Arnoult Quinquet, a pharmacist in Paris, who used the idea originated by Argand and popularized it in France. Quinquet sometimes is credited with the addition of the glass chimney to the lamp. Design The Argand lamp had a sleeve-shaped wick mounted so that air can pass both through the center of the wick and also around the outside of the wick before being drawn into a cylindrical chimney which steadies the flame and improves the flow of air. Early models used ground glass which was sometimes tinted around the wick. An Argand lamp used whale oil, seal oil, colza, olive oil or other vegetable oil as fuel which was supplied by a gravity feed from a reservoir mou ...

Waugoshance Light
The ruined lighthouse at Waugoshance protects boats from a shoal area at the northern end of Lake Michigan. The lighthouse is located in Emmet County, Michigan, United States, and in U.S. Coast Guard District No. 9. It is about west of Mackinaw City. Due to erosion and deterioration, the lighthouse is deteriorating and critically endangered, and likely to fall into the lake in the near future. Reason for lighthouse Boats from Chicago heading North (and ultimately) East need to navigate the narrow tip of northern Lake Michigan, and there are many dangers. The area around Waugoshance Point is not only shallow, it's a large (in area) projection from the bottom of the lake. Boats large enough to safely travel in times of storm cannot approach the light closer than a few hundred yards. Adding to the complication of navigation in this area is the White Shoal, located just north of Waugoshance. This area is currently protected by White Shoal Light—built in 1910, nearby, powerful a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Shoal Light (Michigan)
The White Shoal Light is a lighthouse located west of the Mackinac Bridge in Lake Michigan. It is an active aid to navigation. It is also the tallest lighthouse on the Great Lakes. History Overview The period between 1852 and the beginning of the 20th century saw great activity on the Great Lakes by the United States Lighthouse Board. Between 1852 and 1860 26 new lights were built. Even as the United States Civil War and its aftermath slowed construction, a dozen new lights were still lit in that decade. In the 1870s, 43 new lights were built on the Lakes. The 1880s saw more than one hundred lights constructed.''Beacons in the Night'', Clarke Historical Library. |
Spectacle Reef Light
Spectacle Reef Light is a lighthouse east of the Straits of Mackinac and is located at the northern end of Lake Huron, Michigan. It was designed and built by Colonel Orlando Metcalfe Poe and Major Godfrey Weitzel, and was the most expensive lighthouse ever built on the Great Lakes. Because of the challenges of building on a shoal, including laying an underwater crib, it is said to be the "most spectacular engineering achievement" in lighthouse construction on Lake Huron. It took four years to build because weather limited work to mostly the summer season. Workers lived in a structure at the site; one of the limiting conditions. It ranks high as an engineering achievement among all the lighthouses built on the Great lakes. In 2020, ThSpectacle Reef Preservation Societywas formed and began to restore the lighthouse. History Overview From 1852 to the beginning of the 20th century, the United States Lighthouse Board was active in building lighthouses to support ship traffic on t ...

Fourteen Foot Shoal Light
The lighthouse at Fourteen Foot Shoal was named to note that the lake is only deep at this point, which is a hazard to navigation, ships and mariners. This light is located at the northern end of Lake Huron, Michigan, US, where it is necessary for boats heading to Chicago to pass through a narrow strait and still avoid shallow water. The most common path is to go south of Bois Blanc Island (Michigan). In this channel, the Poe Reef Light marks the northern end of the safe channel and the Fourteen Foot Shoal light marks the southern side of the channel. History The United States Lighthouse Service intended from the time of design that this light would be automated (possibly the first such instance) and operated by radio control from the nearby Poe Reef Light which is away; the keeper's house was never intended to be used as a residence. In 1925 a temporary acetylene buoy was installed there and construction of the permanent light began in 1929 such that the light could begi ...

Fraternal Twin
Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of TwinLast Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share the same sex, while fraternal twins may or may not. In rare cases twins can have the same mother and different fathers (heteropaternal superfecundation). In contrast, a fetus that develops alone in the uterus, womb (the much more common case, in humans) is called a ''singleton'', and the general term for one offspring of a multiple birth is a ''multiple''. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgängers. Statistics The human twin birth rate in the United States rose 7 ...

Cheboygan, Michigan
Cheboygan ( ) is a city in the U.S. state of Michigan. As of the 2010 census, the city population was 4,876. It is the county seat of Cheboygan County. The name of the city shares the name of the county and probably has its origin from the Cheboygan River, although the precise meaning is no longer known. It may have come from an Ojibwe word ''zhaabonigan'' meaning "sewing needle". Alternatively, the origin may have been "Chabwegan," meaning "a place of ore." The city is at the mouth of the Cheboygan River on Lake Huron. U.S. Highway 23 (US 23) connects with Interstate 75 (I-75) at Mackinaw City and the Mackinac Bridge, about to the northwest. Rogers City is about to the southeast. M-27 runs south from the city along the north shore of Mullett Lake to I-75 at Indian River about to the southwest. M-33 runs due south along the east shore of Mullett Lake to M-68 about to the south. History Cheboygan was originally an Ojibwe settlement. In 1844, Jacob Sammons, ...

Poe Reef Light
Poe Reef is a lighthouse located at the east end of South Channel between Bois Blanc Island and the mainland of the Lower Peninsula, about east of Cheboygan, Michigan. Poe Reef has historically caused problems for shipping. Powered vessels heading west to Lake Michigan generally use South Channel, which is approximately three nautical miles wide, but Poe Reef sits close to the middle of the channel, and to the north of it the water is too shallow for lake freighters. History Many attempts were made to position a lightship here but it was difficult. Four different lightships served beginning in 1893: Lightships Nos. 62, 59, 96, and No. 99. The Poe Reef Light was an extension of the effort—beginning in 1870 through 1910—where engineers began to build lights on isolated islands, reefs, and shoals that were significant navigational hazards. Until that time, Light ships were the only practical way to mark the hazards, but were dangerous for the sailors who manned them, and dif ...

Martin Reef Light
The Martin Reef Light Station is a lighthouse located in northern Lake Huron, south of Cadogan Point in Clark Township, Michigan. It was listed on the National Register of Historic Places in 2005. History At the end of the 19th century, the availability of iron ore from the Upper Peninsula caused shipping traffic through the Great Lakes to increase tremendously. Martin Reef, only a few inches deep in its shallowest area, was a significant hazard for ships approaching the Straits of Mackinac. In 1896, the Lighthouse Board asked for funds to be allocated to construct a lightship to station at the reef. However, despite repeated requests, it was not until 1906 that Congress approved the request. Plans were drawn up to construct a lightship designated LV89. In 1907, the Racine-Truscott-Shell Boat building Company of Muskegon, Michigan was awarded a contract to build the steel-hulled vessel. The vessel was completed in 1908, but was not stationed on the reef until the beginning of ... [...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. ''The News'' absorbed the ''Detroit Tribune'' on February 1, 1919, the ''Detroit Journal'' on July 21, 1922, and on November 7, 1960, it bought and closed the faltering ''Detroit Times''. However, it retained the ''Times building, which it used as a printing plant until 1975, when a new facility opened in Sterling Heights, Michigan, Sterling Heights. The ''Times'' building was demolished in 1978. The street in downtown Detroit where the Times building once stood is still called "Times Square (Detroit), Times Square." The Evening News Association, owner of ''The News'', merged with Gannett Company, Gannett in 1985. At the time of its acquisition of ''The News'', Gannett also had other Detroit interests, as its outdoor advertising company, which ultimately became Outfront Media through a series ...
