Yathkyed Lake
Yathkyed Lake (variant: Haecoligua; meaning: "white swan") is a lake in Kivalliq Region, Nunavut, Canada. Located between Angikuni Lake and Forde Lake, it is one of several lakes on the Kazan River. Yathkyed lake was named by the Sayisi Dene, historical barren-ground caribou hunters of the area. Caribou Inuit artifacts have also been found here. Lake Yathkyed contains the only lake on an island in a lake on an island in a lake in the world, and the only islands within such a lake. Geography It is part of the Hearne Domain, Western Churchill province of the Churchill craton, which is the northwest section of the Canadian Shield. According to the Atlas of Canada the geographical centre of the country lies just south of the lake at .

Kivalliq Region
The Kivalliq Region (; Inuktitut syllabics: ᑭᕙᓪᓕᖅ ) is an administrative region of Nunavut, Canada. It consists of the portion of the mainland to the west of Hudson Bay together with Southampton Island and Coats Island. The regional centre is Rankin Inlet. The population was 10,413 in the 2016 Census, an increase of 16.3% from the 2011 Census. Before 1999, Kivalliq Region existed under slightly different boundaries as Keewatin Region, Northwest Territories. Although the Kivalliq name became official in 1999, Statistics Canada has continued to refer to the area as Keewatin Region, Nunavut in publications such as the Census. Most references to the area as "Keewatin" have generally been phased out by Nunavut-based bodies, as that name was originally rooted in a region of northwestern Ontario derived from a Cree dialect, and only saw application onto Inuit-inhabited lands because of the boundaries of the now-defunct District of Keewatin.

Recursive Lake
A recursive island or lake is an island or a lake that lies within a lake or an island. For the purposes of defining recursion, small continental land masses such as Madagascar and Zealandia, New Zealand count as islands, while large continental land masses do not. Islands found within lakes in these countries are often recursive islands because the lake itself is located on an island. Recursive islands Islands in lakes Only a few notable examples are given. Islands in lakes on islands There are nearly 1,000 islands in lakes on islands in Finland alone. Islands in lakes on islands in lakes Islands in lakes on islands in lakes on islands Until 2020, Vulcan Point was an island that existed in Main Crater Lake, Taal, Main Crater Lake on Volcano Island (Philippines), Volcano Island in Lake Taal on Luzon in the Philippines.

Molybdenum
Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin ''molybdaenum'', which is based on Ancient Greek ', meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in 1778 by Carl Wilhelm Scheele. The metal was first isolated in 1781 by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a grey cast, has the sixth-highest melting point of any element. It readily forms hard, stable carbides in alloys, and for this reason most of the world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. Most molybdenum compounds have low solubili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Of Canada
The Atlas of Canada (french: L'Atlas du Canada) is an online atlas published by Natural Resources Canada that has information on every city, town, village, and hamlet in Canada. It was originally a print atlas, with its first edition being published in 1906 by geographer James White and a team of 20 cartographers. Much of the geospatial data used in the atlas is available for download and commercial re-use from the Atlas of Canada site or from GeoGratis. Information used to develop the atlas is used in conjunction with information from Mexico and the United States to produce collaborative continental-scale tools such as the North American Environmental Atlas The ''North American Environmental Atlas'' is an interactive mapping tool created through a partnership of government agencies in Canada, Mexico and the United States, along with the Commission for Environmental Cooperation, a trilateral internati ....

Canadian Shield
The Canadian Shield (french: Bouclier canadien ), also called the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible. As a deep, common, joined bedrock region in eastern and central Canada, the Shield stretches north from the Great Lakes to the Arctic Ocean, covering over half of Canada and most of Greenland; it also extends south into the northern reaches of the United States. Geographical extent The Canadian Shield is a physiographic division comprising four smaller physiographic provinces: the Laurentian Upland, Kazan Region, Davis and James. The shield extends into the United States as the Adirondack Mountains (connected by the Fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribou Inuit
Caribou Inuit ( iu, Kivallirmiut/ᑭᕙᓪᓕᕐᒥᐅᑦ), barren-ground caribou hunters, are Inuit who live west of Hudson Bay in Kivalliq Region, Nunavut, between 61° and 65° N and 90° and 102° W in Northern Canada. They were originally named "Caribou Eskimo" by the Danish Fifth Thule Expedition of 19211924 led by Knud Rasmussen. Caribou Inuit are the southernmost subgroup of the Central Inuit. Groups ;Ahialmiut Ahialmiut relied on caribou year-round. They spent summers on the Qamanirjuaq calving grounds at Qamanirjuaq Lake ("huge lake adjoining a river at both ends") and spent winters following the herd to the north. ;Akilinirmiut Akilinirmiut were located in the Thelon River area by the Akiliniq Hills (''A-ki'', meaning "the other side") to the north of Beverly Lake and also visible above Aberdeen Lake. Some lived northwest of Baker Lake (''Qamani'tuuaq''), along with Qairnirmiut and Hauniqturmiut. Many relocated to Aberdeen Lake because of starvation or education o ...

Nunavut
Nunavut ( , ; iu, ᓄᓇᕗᑦ , ; ) is the largest and northernmost Provinces and territories of Canada#Territories, territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the ''Nunavut Act'' and the ''Nunavut Land Claims Agreement, Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the territorial evolution of Canada, first major change to Canada's political map in half a century since the province of Newfoundland and Labrador, Newfoundland was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the list of the largest country subdivisions by area, fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland).

Barren-ground Caribou
The barren-ground caribou (''Rangifer tarandus groenlandicus''; but subject to a recent taxonomic revision. See Reindeer: Taxomony.) is a subspecies of the reindeer (or the caribou in North America) that is found in the Canadian territories of Nunavut and the Northwest Territories, in northern Alaska and in south-western, Greenland. It includes the Porcupine caribou of Yukon and Alaska.Cronin, M. A., M. D. Macneil, and J. C. Patton (2005). ''Variation in Mitochondrial DNA and Microsatellite DNA in caribou (Rangifer tarandus) in North America.'' Journal of Mammalogy 86(3): 495–505. The barren-ground caribou is a medium-sized caribou, smaller and lighter-colored than the boreal woodland caribou, with the females weighing around and the males around . However, on some of the smaller islands, the average weight may be less. The large migratory herds of barren-ground caribou take their names from the traditional calving grounds, such as the Ahiak herd, the Baffin Island herds, ...
