Sand Hills Light
Sand Hills was an active lighthouse on the shore of Lake Superior is on private property and is currently closed to the public. It is located in Ahmeek in Keweenaw County in the Keweenaw Peninsula, which is the northern part of the Upper Peninsula in Michigan. It was listed in the National Register of Historic Places in 1994. History From 1857 to 1908, Eagle River Light was the only lighthouse between the Keweenaw Waterway and Eagle Harbor Light. With the end of the copper boom in the 1870s the Eagle River, Michigan harbor started to decay. "By the 1890s, it seemed the only ship coming into the harbor was the lighthouse service tender." It was recommended to build a new lighthouse at Sand Hills where most of the lake traffic passing and to decommission Eagle River. A lighthouse at Sand Hills was authorized by Congress in 1893, but no funds were allocated for its construction. Meanwhile, the Eagle River Light was decommissioned and sold in 1908, leaving no navigation light in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior.

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Scotch Cap Light
The Scotch Cap Light is a series of lighthouses located on the southwest corner of Unimak Island in Alaska. It was the first station established on the outside coast of Alaska. History In 1903, the Scotch Cap Light was built. The original lighthouse was a 45-foot (14 meter) wood tower on an octagonal wood building. According to the Coast Guard Historian's Office, the lighthouse was witness to several ship wrecks. In 1909, the cannery supply ship ''Columbia'' wrecked. The 194 crew members were guests of the keepers for two weeks before a rescue ship could remove them. In 1930, the Japanese freighter ''Koshun Maru'' became lost in a snowstorm and beached near the light. In 1940, a new concrete reinforced lighthouse and fog-signal building was erected near the site of the original lighthouse. In 1942, the Russian freighter ''Turksib'' wrecked near the station. The 60 survivors lived at the station for several weeks because rough seas prevented a rescue ship from reaching the station. ...

Dossin Great Lakes Museum
The Dossin Great Lakes Museum is an historical maritime museum in Detroit, Michigan. Located on The Strand on Belle Isle State Park (Michigan), Belle Isle Park along the Detroit River, this museum places special interest on Detroit's role on national and regional maritime history. The museum features exhibits such as one of the largest collection of model ships in the world, and the bow anchor of the SS Edmund Fitzgerald, SS ''Edmund Fitzgerald'', which went down in a storm in 1975. History This was founded in 1949 as the City Maritime Museum aboard the ''J. T. Wing'' wooden schooner, the last commercial sailing ship on the Great Lakes. The museum closed by 1956, less than a decade later, because of the deteriorating condition of the schooner. With $125,000 in donations from Detroit's Dossin family, and a matching subsidy by the city's historical commission, the Dossin Great Lakes Museum broke ground on Belle Isle on May 21, 1959, near the former mooring of the ''J. T. Wing.'' ... [...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.

Boatnerd
The boatnerd corporation, a registered not for profit corporation, circulates information about vessels that ply the North American Great Lakes. When Acheson Ventures provided space for a headquarters for the organization in their Maritime Center overlooking the St Clair River, they called boatnerd ''"the most widely-used website for Great Lakes maritime information."'' Reporters consider the boatnerd site reliable enough that they cite or quote it by name in their articles. The organization was profiled by ''The Globe and Mail'' in 2008. The organization holds annual festivals, at sites of interest to those interested in maritime commerce on the Great Lakes. ''The Globe and Mail'' profiled boatnerd when the 2008 festival was held in a shipyard in Port Colborne, Ontario, where the ''Calumet'', an 80-year-old lake freighter was being scrapped. According to ''The Globe and Mail'' the site gets over 20 million page views a month. According to ''The Globe and Mail'' the site's voluntee ...

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barracks
Barracks are usually a group of long buildings built to house military personnel or laborers. The English word originates from the 17th century via French and Italian from an old Spanish word "barraca" ("soldier's tent"), but today barracks are usually permanent buildings for military accommodation. The word may apply to separate housing blocks or to complete complexes, and the plural form often refers to a single structure and may be singular in construction. The main object of barracks is to separate soldiers from the civilian population and reinforce discipline, training, and ''esprit de corps''. They have been called "discipline factories for soldiers". Like industrial factories, some are considered to be shoddy or dull buildings, although others are known for their magnificent architecture such as Collins Barracks in Dublin and others in Paris, Berlin, Madrid, Vienna, or London. From the rough barracks of 19th-century conscript armies, filled with hazing and illness and bare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
