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 Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first ..., 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 highe ...

Nahanni Range Road
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 1986, the road fell into disuse and maintenance became increasingly difficult. Since the mine resume ...

Mountain Ranges Of Yukon
Yukon (population as of the 2021 Canadian census, 2021 census 40,232) is in the northwestern corner of Canada and is bordered by Alaska, British Columbia and the Northwest Territories. The sparsely populated territory abounds with natural scenery, snowmelt lakes and perennial white-capped mountains, including many of Canada's highest mountains. The territory's climate is Climate of the Arctic, Arctic in territory north of Old Crow, Yukon, Old Crow, Subarctic climate, 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 Taiga, 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 U.S. state, American state of Alaska to the west, the Northwest Territories to the east and British Columbia to the south.

Journal Of Vertebrate Paleontology
The ''Journal of Vertebrate Paleontology'' is a bimonthly peer-reviewed scientific journal that was established in 1980 by Jiri Zidek (University of Oklahoma). It covers all aspects of vertebrate paleontology, including vertebrate origins, evolution, functional morphology, taxonomy, biostratigraphy, paleoecology, paleobiogeography, and paleoanthropology. The journal is published by Taylor & Francis on behalf of the Society of Vertebrate Paleontology. According to ''Journal Citation Reports'', the journal has a 2017 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking.

Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 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 third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. 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) ...

Mount Nirvana
Mount Nirvana, at is the unofficial name of the highest mountain in the Northwest Territories, Canada. The mountain is a 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 time. Before 2016, only five successful ascent were recorded, all with the assistance of helicopters or floatplane. In June 2016, Nirvana was climbed without assistance for the first time.

Canol Road
The Canol Road was part of the Canol Project and was built to construct a pipeline from Norman Wells, Northwest Territories southwest 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 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.

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 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] |
