Sahtú Divisional Education Council
The Sahtú or North Slavey (historically called ''Hare'' or ''Hareskin Indians'') are a Dene First Nations people of the Athabaskan-speaking ethnolinguistic group living in the vicinity of Great Bear Lake (''Sahtú'', the source of their name), Northwest Territories, Canada. The Sahtú peoples live in Colville Lake, Deline, Fort Good Hope, Norman Wells and Tulita which form the Sahtu Region of the NWT. The Dene of the region are represented by the Sahtu Dene Council who, in 1993, signed the Sahtu Dene and Metis Comprehensive Land Claim Agreement. Sahtú groups include the ''Hare Dene'' (K'ahsho Got'ine District, today: Colville Lake and Fort Good Hope), ''Bear Lake Dene'' (Déline District), and ''Mountain Dene'' (Tulit'a District). They call themselves also ''Ɂehdzo Got’ı̨ne'' (Trap People). Ethnography An early description of Sahtú cultures is given in Alexander Mackenzie's journal of his voyage down the Mackenzie River to the Arctic Ocean in 1789. Although there ...

Hare Indian Dog
The Hare Indian dog is an extinct domesticated Canis, canine; possibly a breed of domestic dog, coydog, or domesticated coyote; formerly found and originally bred in northern Canada by the Hare Indians for coursing. It had the speed and some characteristics of the coyote, and the domesticated temperament and other characteristics of a domestic dog. It gradually lost its usefulness as Indigenous peoples, aboriginal hunting methods declined, and became extinct or lost its separate identity through interbreeding with dogs in the 19th century, though some claim the breed still exists in modified form.

Athabaskan Languages
Athabaskan ( ; also spelled ''Athabascan'', ''Athapaskan'' or ''Athapascan'', and also known as Dene) is a large branch of the Na-Dene languages, Na-Dene language family of North America, located in western North America in three areal language groups: Northern, Pacific Coast and Southern (or Apachean). Kari and Potter (2010:10) place the total territory of the 53 Athabaskan languages at . Chipewyan language, Chipewyan is spoken over the largest area of any North American native language, while Navajo language, Navajo is spoken by the largest number of people of any native language north of Mexico. The word ''Athabaskan'' is an Anglicisation, anglicized version of a Cree language name for Lake Athabasca ( '[where] there are reeds one after another') in Canada. Cree is one of the Algonquian languages and therefore not itself an Athabaskan language. The name was assigned by Albert Gallatin in his 1836 (written 1826) classification of the languages of North America. He acknowledged ...

Port Radium
Port Radium is a mining area on the eastern shore of Great Bear Lake, Northwest Territories, Canada. It included the settlement of Cameron Bay as well as the Eldorado (also called Port Radium) and Echo Bay mines. The name Port Radium did not come into use until 1936 and at the time it was in reference to the region as a whole. The Eldorado mine site at LaBine Point adopted the name for its settlement in the 1940s and it has generally stuck. Location Port Radium is situated at on LaBine Point on the McTavish Arm of Great Bear Lake. Cameron Bay is situated southeast at and Port Radium Airport is at between the two to the north and consisted of a gravel airstrip next to Glacier Lake. History During a field trip along the east arm of Great Bear Lake in August 1900, James McIntosh Bell of the Geological Survey of Canada noted evidences of iron, copper, uranium and cobalt in the vicinity of Echo Bay. Thirty years later, a prospector Gilbert LaBine discovered high-gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eldorado Mine (Northwest Territories)
The Eldorado Mine is a defunct mine located in Port Radium, Northwest Territories, Canada. The site, which covers 12 hectares, is located next to Echo Bay in the shore of Great Bear Lake. The mine was 270 miles by air north of Yellowknife and approximal 850 miles north of Edmonton, on the edge of the Arctic Circle and therefore only accessible by small charter aircraft equipped with floats or skis, or larger charter aircraft flying to the south shore of the lake, followed by a boat journey. Radium, uranium and silver were extracted from the mine during several working periods between 1932 and 1982. Uranium from Eldorado was used in the Manhattan Project. The Eldorado Mine is also known as Port Radium, a name adopted for use at this specific site after 1942. The name Port Radium had previously referred to the post office and wireless radio station at Cameron Bay.

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include firestorms, extreme heat and ionizing radiation, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. The first nuclear weapons were developed by the Allied Manhattan Project during World War II. Their production continues to require a large scientific and industrial complex, pr ...

Radium
Radium is a chemical element; it has chemical symbol, symbol Ra and atomic number 88. It is the sixth element in alkaline earth metal, group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1,600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. For this property, it was widely used in Self-luminous paint, self-luminous paints following its discovery. Of the Radionuclide, radioactive elements that occur in quantity, radium is considered particularly Toxicity, toxic, and it is Carcinogen, carcinogenic due to the radioactivity of both it and its immediate decay product radon as well as its tendency to B ...

Radioactive Decay
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered ''radioactive''. Three of the most common types of decay are Alpha decay, alpha, Beta decay, beta, and Gamma ray, gamma decay. The weak force is the Fundamental interactions, mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic force, electromagnetic and nuclear forces. Radioactive decay is a randomness, random process at the level of single atoms. According to quantum mechanics, quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as a half-life. The half-lives of radioactive atoms have a huge range: f ...

Manhattan Project
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project. The project absorbed its earlier British counterpart, Tube Alloys, and subsumed the program from the American civilian Office of Scientific Research and Development. The Manhattan Project employed nearly 130,000 people at its peak and cost nearly US$2 billion (equivalent to about $ b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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] |
Alexander Mackenzie (explorer)
Sir Alexander Mackenzie ( – 12 March 1820) was a Scottish explorer and fur trader known for accomplishing the first crossing of North America north of Mexico by a European in 1793. The Mackenzie River and Mount Sir Alexander are named after him. As a leading member of the North West Company, he aspired to extend the Company's operations into western Canada and selling those furs in China. His hopes thus were intrusions on the monopoly positions of both the Hudson's Bay Company and the East India Company. Early life Mackenzie was born in Stornoway in Isle of Lewis, Lewis. He was the third of the four children born to Kenneth 'Corc' Mackenzie (1731–1780) and his wife Isabella MacIver, from another prominent mercantile family in Stornoway. When only 14 years old, Mackenzie's father served as an Ensign (rank), ensign to protect Stornoway during the Jacobite rising of 1745. He later became a merchant and held the Tacksman, tack of Melbost; his grandfather being a younger brot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
