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. Yukon covers , of which is land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaufort Sea
The Beaufort Sea ( ; ) is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, Yukon, and Alaska, and west of the Canadian Arctic Archipelago. The sea is named after Sir Francis Beaufort, a Hydrography, hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores. The sea, characterized by severe climate, is frozen over most of the year. Historically, only a narrow pass up to opened in August–September near its shores, but recently due to climate change in the Arctic the ice-free area in late summer has greatly enlarged. Until recently, the Beaufort Sea was known as an important reservoir for the replenishment of Arctic sea ice. Sea ice would often rotate for several years in the Beaufort Gyre, the dominant ocean current of the Beaufort Sea, growing into sturdy and thick multi-year ice. Claims that the seacoast was p ...

Kluane National Park And Reserve
Kluane National Park and Reserve (; ) are two protected areas in the southwest corner of the Provinces and territories of Canada, territory of Yukon. The National Park Reserve was set aside in 1972 to become a national park, pending settlement of First Nations in Canada, First Nations land claims. It covered an area of . When agreement was reached with the Champagne and Aishihik First Nations over an eastern portion of the Reserve, that part—about —became a national park in 1993, and is a unit of the national park system administered co-operatively with Parks Canada. The larger western section remains a Reserve, awaiting a final land claim settlement with the Kluane First Nation. The park borders British Columbia to the south, while the Reserve borders both British Columbia to the south, and the United States (Alaska) to the south and west. The Reserve includes the highest mountain in Canada, Mount Logan () of the Saint Elias Mountains. Mountains and glaciers, including Donj ...

Plateau
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming p ...

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] |
American Cordillera
The American Cordillera ( ) is a chain of mountain ranges (cordilleras), consisting of an almost continuous sequence of mountain ranges that form the western "backbone" of the Americas. Aconcagua is the highest peak of the chain. It is also the backbone of the volcanic arc that forms the eastern half of the Pacific Ring of Fire. Description North America The overlapping and parallel ranges begin in the north with the Alaska Range and the Brooks Range in Alaska, and run through the Yukon into British Columbia. The main belt of the Rocky Mountains along with the parallel Columbia Mountains and Coast Ranges of mountains and islands continue through British Columbia and Vancouver Island. In the United States, the Cordillera branches include the Rockies, the Sierra Nevada, the Cascades, and various small Pacific coastal ranges. In Mexico, the Cordillera continues through the Sierra Madre Occidental and Sierra Madre Oriental, as well as the backbone mountains of the Baja Cali ...

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. It spans an area of approximately and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has also been described as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing world ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the ...

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 ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mackenzie River
The Mackenzie River (French: ; Slavey language, Slavey: ' [tèh tʃʰò], literally ''big river''; Inuvialuktun: ' [kuːkpɑk], literally ''great river'') is a river in the Canadian Canadian boreal forest, boreal forest and tundra. It forms, along with the Slave River, Slave, Peace River, Peace, and Finlay River, Finlay, the longest river system in Canada, and includes the second largest drainage basin of any North American river after the Mississippi River, Mississippi. The Mackenzie River flows through a vast, thinly populated region of forest and tundra entirely within the Northwest Territories in Canada, although its many tributaries reach into five other Provinces and territories of Canada, Canadian provinces and territories. The river's mainstem (hydrology), main stem is long, flowing north-northwest from Great Slave Lake into the Arctic Ocean, where it forms a large River delta, delta at its mouth. Its extensive watershed drains about 20 percent of Canada. It is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukon River
The Yukon River is a major watercourse of northwestern North America. From its source in British Columbia, it flows through Canada's territory of Yukon (itself named after the river). The lower half of the river continues westward through the U.S. state of Alaska. The river is long and empties into the Bering Sea at the Yukon–Kuskokwim Delta. The average flow is . The total drainage area is , of which lies in Canada. The total area is more than 25% larger than Texas or Alberta. The longest river in Alaska and Yukon, it was one of the principal means of transportation during the 1896–1903 Klondike Gold Rush. A portion of the river in Yukon—"The Thirty Mile" section, from Lake Laberge to the Teslin River—is a Canadian Heritage Rivers System, national heritage river and a unit of Klondike Gold Rush International Historical Park. Paddle-wheel riverboats continued to ply the river until the 1950s, when the Klondike Highway was completed. After the purchase of Alaska by the Un ...
