Mackenzie Mountains
The Mackenzie Mountains are a Canadian mountain range forming part of the Yukon-Northwest Territories boundary between the Liard and Peel rivers. The range is named in honour of Canada's second prime minister, Alexander Mackenzie. Nahanni National Park Reserve and Nááts'ihch'oh National Park Reserve are in the Mackenzie Mountains. The mining town of Tungsten, site of the Cantung Mine, is in the Mackenzie Mountains. Only two roads lead into the Mackenzie Mountains, both in Yukon: the Nahanni Range Road leading to the townsite of Tungsten and the Canol Road leading to the Macmillan Pass. The highest mountain in this range is Keele Peak at , in Yukon. The second-highest mountain is Mount Nirvana. It is, at , the highest mountain in the Northwest Territories. The Silurian fish family Archipelepididae has been described from specimens found in the Mackenzie Mountains.Soehn, K. L., Märss, T., Caldwell, M. W. & Wilson, M. V.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Cantung Mine
Cantung Mine is a tungsten producer in the Nahanni area of the Northwest Territories, Canada, located northeast of Watson Lake in the Flat River Valley of the Selwyn Range close to the Yukon border. Tungsten was originally discovered in the area in 1954 by prospectors. Cantung Mine operated from 1962 to 1986, again from 2002 to 2003, and from 2005. Production was suspended from October 2009 to October 2010. The mine owner, North American Tungsten Corporation, went bankrupt in 2015 and the mine closed in October of that year. The federal government of Canada now owns the mine and has to clean up the site. As of December, 2017, the mine remained closed, with the possibility of being opened to process a nearby lithium deposit. As of February 2019, the mine is still closed; the federal and NWT governments are trying to sell it. 1962—1986 The original company that developed the mine was Canada Tungsten Mining Corporation Limited, with ''Cantung'' being a short abbreviated form o ...

Mountain Ranges Of Yukon
Yukon is in the northwestern corner of Canada and is bordered by Alaska and the Northwest Territories. The sparsely populated territory abounds with natural scenic beauty, with snowmelt lakes and perennial white-capped mountains, including many of Canada's highest mountains. The territory's climate is Arctic in territory north of Old Crow, subarctic in the region, between Whitehorse and Old Crow, and humid continental climate south of Whitehorse and in areas close to the British Columbia border. Most of the territory is boreal forest with tundra being the main vegetation zone only in the extreme north and at high elevations. The territory is about the shape of a right triangle, bordering the American state of Alaska to the west, the Northwest Territories to the east and British Columbia to the south. Yukon covers 482,443 km2, of which 474,391 km2 is land and 8,052 km2 is water, making it the forty-first largest subnational entity in the world, and, among the fifty l ...

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Nirvana
Mount Nirvana, at is the unofficial name of the highest mountain in the Northwest Territories, Canada. Currently the Canadian government is working to officially recognize the name ''Thunder Mountain'', reflecting the local Dehcho First Nation name for the mountain. Today, the name ''Mt. Nirvana'' is commonly depicted in alpine literature. Mount Nirvana is part of Nahanni National Park Reserve, the largest national park in the Northwest Territories. History Part of the Mackenzie Mountains, it was first climbed by Bill Buckingham and Lew Surdam in July 1965.Principal heights by range or region from Buckingham gave the mountain the moniker of "Mount Nirvana" at that ti ...

Canol Road
The Canol Road was part of the Canol Project and was built to construct a pipeline from Norman Wells, Northwest Territories, to Whitehorse, Yukon, during World War II. The pipeline no longer exists, but the long Yukon portion of the road is maintained by the Yukon Government during summer months. The portion of the road that still exists in the NWT is called the Canol Heritage Trail. Both road and trail are incorporated into the Trans-Canada Trail. The Canol Road starts at Johnsons Crossing, Yukon, Johnson's Crossing on the Alaska Highway near the Teslin River bridge, east of Whitehorse, Yukon, and runs to the Northwest Territories border. The highway joins the Robert Campbell Highway near Ross River, Yukon, where there is a cable ferry across the Pelly River, and an old footbridge, still in use, that once supported the pipeline.

Nahanni Range Road
:Yukon Highway 10 :''Northwest Territories, no official route number'' (maintained by mining company) The Nahanni Range Road was completed in the early 1960s from Watson Lake, Yukon along the present alignment of the Robert Campbell Highway to Miner Junction (aka Cantung Junction), thence along the Highway 10 route, across the border into the Northwest Territories to the privately owned mining town, Tungsten (for the tungsten mined there), and the Cantung Mine (for Canada Tungsten Mining Corporation). The portion between Cantung Junction and Watson Lake has, since 1971, been part of the Robert Campbell Highway (Yukon Highway 4). The Nahanni Range Road proper is entirely gravel, and is not recommended for general public use. Originally, two-thirds of the route was maintained by the Yukon government, and had campgrounds for public use. The remaining third was maintained by the mining company, open to public traffic, but with no public facilities at the town. When the mine shut in ...

Tungsten, Northwest Territories
The townsite of Tungsten (shown as Cantung on some maps) is located at Cantung Mine in the Northwest Territories. It is accessible from Watson Lake, Yukon via the Nahanni Range Road History Tungsten was built in 1961 and the tungsten mine went into operation in 1962 as a large open-pit mine in the Mackenzie Mountains. It originally consisted of several small bungalow houses. Total population of Tungsten during the 1960s was approximately 120 persons, including about 27 families. In 1968 families were housed in 28 units (single and duplex housing). Because of extremely good wages and benefits, turnover rates for the entire operation were quite low. Families benefited from the K-8 Grade school, and later a K-9 system. During the summer months, because of the open pit operation, manpower and townsite population grew to 160. In the mid-1970s, the townsite expanded to include a trailer court, three condominiums, bunkhouse trailers, and in 1982, a modern recreation complex. An 80 ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
