Duluth Ship Canal
The Duluth Ship Canal is an artificial canal cut through Minnesota Point, providing direct access to Duluth harbor from Lake Superior. Begun privately in 1871, it was put under federal supervision and maintenance several years later. It is still an important component of the harbor facilities. In its current configuration, the canal is defined by a pair of breakwaters long and apart, constructed of concrete set on timber and stone cribbing. HAER No. MN-10 The canal is maintained at wide and LWD, allowing passage of ocean-going ships. Three lighthouses are placed on the sides of the canal: the Duluth North Pier Light and the Duluth South Breakwater Outer Light mark the lake ends of the canal, while the Duluth South Breakwater Inner Light functions with the south breakwater light as a range light. At the harbor end, the canal is straddled by the Aerial Lift Bridge which connects Minnesota Point to the rest of the city. On the north side, there is a building housing the local Co ...

Historic American Engineering Record In Minnesota
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Canals In Minnesota
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Canals
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Chisholm, Minnesota
Chisholm is a city in St. Louis County, Minnesota, United States. The population was 4,976 at the 2010 census. The city has been called "The Heart of the Iron Range" due to its location in the middle of the Mesabi Iron Range. History The city was named for its founder, Archibald Mark Chisholm (1862–1933), a mining man and investor from Glengarry County, Ontario, Canada. Chisholm was incorporated in 1901. A post office called Chisholm has been in operation since 1901. With a railroad line to Duluth and plenty of mining work available in and near town, Chisholm's population grew rapidly, and by 1908 it had more than 6,000 people and 500 buildings. On September 5, 1908, a fast-moving forest fire obliterated the town due to dry conditions and the wooden construction of nearly all the town's buildings. Many people escaped by going into the lake. No one died in the fire. Afterward, building codes were enhanced, and by the next summer more than 70 fireproof buildings had been erected ...

William Boeing
William Edward Boeing (; October 1, 1881 – September 28, 1956) was an American aviation pioneer who founded the Pacific Airplane Company in 1916, which a year later was renamed to The Boeing Company, now the largest exporter in the United States by dollar value and among the largest aerospace manufacturers in the world. William Boeing's first design was the Boeing Model 1 (or B & W Seaplane), which first flew in June 1916, a month before the company was founded. He also helped create the United Aircraft and Transport Corporation (known as "United Airlines" today) in 1929 and served as its chairman. He received the Daniel Guggenheim Medal in 1934 and was posthumously inducted in to the National Aviation Hall of Fame in 1966, ten years after his death. Early life William Boeing was born in Detroit, Michigan, to Marie M. Ortmann, from Vienna, Austria, and Wilhelm Böing (1846–1890) from Hohenlimburg, Germany.

Near the Twin Ports of Duluth, Minnesota and Superior, Wisconsin, the river becomes a freshwater estuary. History According to Warren Upham, the Ojibwe name of the river is ''Gichigami-ziibi'' (Great-lake River). He notes: "The river was probably so named by Pierre Gaultier de Varennes, sieur de La Vérendrye (1685–1749), who was a very active explorer, in the years 1731 and onward. Shortly before his death the king of France in 1749 conferred on him the cross of Saint Louis as a recognition of the importance of his discoveries, and thence the name of the Saint Louis River appears to ...

Dike (flood Prevention)
A levee (), dike (American English), dyke (Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters. Etymology Speakers of American English (notably in the Midwest and Deep South) use the word ''levee'', from the French word (from the feminine past participle of the French verb , 'to raise'). It originated i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Superior And Mississippi Railroad
The Lake Superior and Mississippi Railroad is the name for two different railroads in Minnesota. Historic railroad The Lake Superior and Mississippi Railroad (LS&M) was the first rail link between the Twin Cities and Duluth and came into existence in 1863 when financier Jay Cooke selected Duluth as the northern end of a new railroad. Lyman Dayton, a local businessman put up $10,000 of his own money to do the original surveying work and served as the railroad's president until his death in 1865. Dayton was succeeded as president by Frank Hamilton Clark, a Philadelphia banker whose family firm gave Cooke his start in the financial industry. The LS&M was completed in 1870, running through the city of Carlton and running along the path of the Saint Louis River to Duluth. Later that year the first passenger trains started running between the Twin Cities and Duluth. The LS&M was a victim of the Panic of 1873, as Jay Cooke's company was overextended and burdened with financial commitm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
