Ironworld Discovery Center
The Minnesota Discovery Center, formerly known as Ironworld Discovery Center and originally as the Iron Range Interpretive Center, opened in the 1977 outside Chisholm, Minnesota, United States. It showcases northeastern Minnesota's "history and future" and includes a museum, entertainment venue, research center and library, and a park. The site offers various community programs and events including Polka fests, concerts, and fairs. The property includes a memorial to Rudy Perpich and holds historical documents and artifacts related to mining in the Iron Range. History The museum complex opened in 1977 as the Iron Range Interpretive Center with 34 exhibits and was renamed in 1984 as Ironworld USA. In 2009 it became the Minnesota Discovery Center. It was built to celebrate the immigrants who built Minnesota's Iron Range mining region, including Italians, Finns, and Yugoslavs. It was supposed to draw tourists from around the state and other parts of the U.S., but in the late 1990s ...

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 ...

Tram
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the Unit ...

History Museums 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 ...

Taconite
Taconite () is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or ''taconyte''. Following development of high grade direct shipping iron ore deposits on the Mesabi Range, containing up to 65% iron and as little as 1.25% silica, miners termed the unaltered iron-formation wall rock taconite. The iron content of taconite is generally 30% to 35%, and the silica content generally around 45%. Iron in 'taconite' is commonl ...

Immigration
Immigration is the international movement of people to a destination country of which they are not natives or where they do not possess citizenship in order to settle as permanent residents or naturalized citizens. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however. As for economic effects, research suggests that migration is beneficial both to the receiving and sending countries. Research, with few exceptions, finds that immigration on average has positive economic effects on the native population, but is mixed as to whether low-skilled immigration adversely affects low-skilled natives. Studies show that the elimination of barriers to migration would have profound effects on world GDP, with estimates of gains ranging between 67 and 147 percent for the scenarios in which 37 to 53 percent of the developing countries' workers migrate ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Shaft Mining
Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shaft (civil engineering), Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means. Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinker (mining), sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa. The modern shaft sinking industry is gradually shifting further towards greater mechanisation. Recent innovations in the form of full-face shaft boring (akin to a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minnesota
Minnesota () is a state in the upper midwestern region of the United States. It is the 12th largest U.S. state in area and the 22nd most populous, with over 5.75 million residents. Minnesota is home to western prairies, now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed, and settled; and the less populated North Woods, used for mining, forestry, and recreation. Roughly a third of the state is covered in forests, and it is known as the "Land of 10,000 Lakes" for having over 14,000 bodies of fresh water of at least ten acres. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub. With a population of about 3.7 million, the Twin Cities is the 16th largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas in the state include Duluth, Mankato, Moorhead, Rochester, and ...

Yugoslavs
Yugoslavs or Yugoslavians ( Bosnian and Croatian: ''Jugoslaveni'', Serbian and Macedonian ''Jugosloveni''/Југословени; sl, Jugoslovani) is an identity that was originally designed to refer to a united South Slavic people. It has been used in two connotations, the first in a sense of common shared ethnic descent, i.e. panethnic or supraethnic connotation for ethnic South Slavs, and the second as a term for all citizens of former Yugoslavia regardless of ethnicity. Cultural and political advocates of Yugoslav identity have historically ascribed the identity to be applicable to all people of South Slav heritage, including those of modern Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, Serbia, and Slovenia. Although Bulgarians are a South Slavic group, attempts at uniting Bulgaria into Yugoslavia were unsuccessful, and therefore Bulgarians were not included in the panethnic identification. Since the dissolution of Yugoslavia and the establishment of So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finns
Finns or Finnish people ( fi, suomalaiset, ) are a Baltic Finnic ethnic group native to Finland. Finns are traditionally divided into smaller regional groups that span several countries adjacent to Finland, both those who are native to these countries as well as those who have resettled. Some of these may be classified as separate ethnic groups, rather than subgroups of Finns. These include the Kvens and Forest Finns in Norway, the Tornedalians in Sweden, and the Ingrian Finns in Russia. Finnish, the language spoken by Finns, is closely related to other Balto-Finnic languages, e.g. Estonian and Karelian. The Finnic languages are a subgroup of the larger Uralic family of languages, which also includes Hungarian. These languages are markedly different from most other languages spoken in Europe, which belong to the Indo-European family of languages. Native Finns can also be divided according to dialect into subgroups sometimes called ''heimo'' (lit. ''tribe''), although suc ...
