Ore Dock
An ore dock is a large structure used for loading ore (typically from railway cars or ore jennies) onto ships, which then carry the ore to steelworks or to transshipment points. Most known ore docks were constructed near iron mines on the upper Great Lakes and served the lower Great Lakes. Ore docks still in existence are typically about wide, high, and vary from to in length. They are commonly constructed from wood, steel, reinforced concrete, or combinations of these materials. They are commonly used for loading bulk ore carriers with high mass, low-value ore, such as iron ore, in raw or taconite form. Construction Ore docks are typically long, high structures, with a railway track or tracks along the top and a number of "pockets" into which ore is unloaded from railcars, typically by gravity. Each pocket has a chute that can be lowered to discharge the ore into the hold of a ship berthed alongside. The use of pockets and chutes allows the dock itself to be loaded with ...

Soo Locks
The Soo Locks (sometimes spelled Sault Locks but pronounced "soo") are a set of parallel Lock (water navigation), locks, operated and maintained by the United States Army Corps of Engineers, Detroit District, that enable ships to travel between Lake Superior and the lower Great Lakes. They are located on the St. Marys River (Michigan–Ontario), St. Marys River between Lake Superior and Lake Huron, between the Upper Peninsula of Michigan, Upper Peninsula of the U.S. state of Michigan and the Provinces and territories of Canada, Canadian province of Ontario. They bypass the rapids of the river, where the water falls . The locks pass an average of 10,000 ships per year, despite being closed during the winter from January through March, when ice shuts down shipping on the Great Lakes. The winter closure period is used to inspect and maintain the locks. The locks share a name (usually shortened and anglicized as ''Soo'') with the two cities named Sault Ste. Marie, Sault Ste.

Portage
Portage or portaging ( CA: ; ) is the practice of carrying water craft or cargo over land, either around an obstacle in a river, or between two bodies of water. A path where items are regularly carried between bodies of water is also called a ''portage.'' The term comes from French, where means "to carry", as in "portable". In Canada, the term "carrying-place" was sometimes used. Early French explorers in New France and French Louisiana encountered many rapids and cascades. The Native Americans carried their canoes over land to avoid river obstacles. Over time, important portages were sometimes provided with canals with locks, and even portage railways. Primitive portaging generally involves carrying the vessel and its contents across the portage in multiple trips. Small canoes can be portaged by carrying them inverted over one's shoulders and the center strut may be designed in the style of a yoke to facilitate this. Historically, voyageurs often employed tump lines on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schooner
A schooner ( ) is a type of sailing ship, sailing vessel defined by its Rig (sailing), rig: fore-and-aft rigged on all of two or more Mast (sailing), masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a Topgallant sail, topgallant. Differing definitions leave uncertain whether the addition of a Course (sail), fore course would make such a vessel a brigantine. Many schooners are Gaff rig, gaff-rigged, but other examples include Bermuda rig and the staysail schooner. Etymology The term "schooner" first appeared in eastern North America in the early 1700s. The term may be related to a Scots language, Scots word meaning to skip over water, or to skip stones. History The exact origins of schooner rigged vessels are obscure, but by early 17th century they appear in paintings by Dutch marine artists. The earliest known il ...

Plank Road
A plank road is a road composed of Plank (wood), wooden planks or wikt:puncheon#Noun, puncheon logs, as an efficient technology for traversing soft, marshy, or otherwise difficult ground. Plank roads have been built since antiquity, and were commonly found in the Canadian province of Ontario as well as the Northeastern United States, Northeast and Midwestern United States, Midwest of the United States in the first half of the 19th century. They were often built by toll road, turnpike companies. Origins The Wittmoor bog trackway is the name given to each of two historic plank roads or boardwalks, trackway No. I being discovered in 1898 and trackway No. II in 1904 in the ''Wittmoor'' bog in northern Hamburg, Germany. The trackways date to the 4th and 7th century AD, both linked the eastern and western shores of the formerly inaccessible, swampy bog. A part of the older trackway No. II dating to the period of the Roman Empire is on display at the permanent exhibition of the Archäol ...

Mule
The mule is a domestic equine hybrid between a donkey, and a horse. It is the offspring of a male donkey (a jack) and a female horse (a mare). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a male horse (a stallion) and a female donkey (a jenny). Mules vary widely in size, and may be of any color seen in horses or donkeys. They are more patient, hardier and longer-lived than horses, and are perceived as less obstinate and more intelligent than donkeys. Terminology A female mule is often called a "molly" or "Molly mule," though the correct term is "mare mule." A male mule is called a "john" or "John mule," though the correct term is "horse mule." A young male mule is called a "mule colt," and a young female is called a "mule filly." The donkey used to produce mules is called a "mule ja ...

Marquette Iron Range
The Marquette Iron Range is a deposit of iron ore located in Marquette County, Michigan in the United States. The towns of Ishpeming and Negaunee developed as a result of mining this deposit. A smaller counterpart of Minnesota's Mesabi Range, this is one of two iron ranges in the Lake Superior basin that are in active production as of 2018. The iron ore of the Marquette Range has been mined continuously from 1847 until the present day. Marquette Iron Range is the deposit's popular and commercial name; it is also known to geologists as the Negaunee Iron Formation. History The geology of the district consists of middle Precambrian rocks in the Animikie Group, which form a westward plunging syncline long and wide. The principal iron ore is found in the Negaunee Iron formation. This formation is thick near Negaunee. This is a magnetite or hematite chert. Natural ore deposits are located in synclines and up against mafic dikes. Beneficiation commenced in 1954 and this concent ...

Upper Peninsula
The Upper Peninsula of Michigan—also known as Upper Michigan or colloquially the U.P. or Yoop—is the northern and more elevated of the two major landmasses that make up the U.S. state of Michigan; it is separated from the Lower Peninsula by the Straits of Mackinac. It is bounded primarily by Lake Superior to the north, separated from the Canadian province of Ontario at the east end by the St. Marys River, and flanked by Lake Huron and Lake Michigan along much of its south. Although the peninsula extends as a geographic feature into the state of Wisconsin, the state boundary follows the Montreal and Menominee rivers and a line connecting them. First inhabited by Algonquian-speaking native American tribes, the area was explored by French colonists, then occupied by British forces, before being ceded to the newly established United States in the late 18th century. After being assigned to various territorial jurisdictions, it was granted to the newly formed state of Michigan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
