Coal In Alberta
Coal in Alberta is found in the Coalspur Formation in the Western Canada Sedimentary Basin in the foothills of southwestern Alberta. The Coalspur Formation, which has large quantities of high-quality coal, runs from south of the Wapiti River to the North Saskatchewan River. The Coalspur coal zone is about to thick. Coal formations in what is now the province of Alberta, originated approximately 140 and 65 million years ago. The collision between the two immense plates had pushed up the Rocky Mountains while depressing the North American continent's interior. New layers of growth crushed and buried layers of peat, shale, and sandstone, compressing them into coal beds. The oldest coal deposits were pushed closer to the surface about 80 to 55 million years ago, forming part of the Rocky Mountains's foothills and Front Ranges. In 2018, Alberta's coal production totalled approximately 20 million tonnes and accounted for $10 million in royalties for the province, according to Albe ...

Coalspur Formation
The Coalspur Formation is an Upper Cretaceous to lower Palaeocene stratigraphic unit of the Western Canada Sedimentary Basin in the foothills of southwestern Alberta. Its deposition spanned the time interval from latest Cretaceous (Maastrichtian) to early Palaeocene, and it includes sediments that were deposited before, during, and after the Cretaceous-Paleogene (K-Pg) extinction event. It includes the economically important coal deposits of the Coalspur Coal Zone, as well as nonmarine plant and animal fossils. Lithology The sediments of the Coalspur Formation were eroded from the Canadian Cordillera, and were transported eastward by river systems and deposited in fluvial channel and floodplain environments. The formation consists primarily of sandstones and siltstones, interbedded with mudstones and minor amounts of bentonite. Thick coal seams are present locally in the upper portion of the formation, especially in the Alberta Coal Branch area southeast of Hinton, Alberta. Near ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Hudson's Bay Company
The Hudson's Bay Company (HBC; french: Compagnie de la Baie d'Hudson) is a Canadian retail business group. A fur trading business for much of its existence, HBC now owns and operates retail stores in Canada. The company's namesake business division is Hudson's Bay, commonly referred to as The Bay ( in French). After incorporation by English royal charter in 1670, the company functioned as the ''de facto'' government in parts of North America for nearly 200 years until the HBC sold the land it owned (the entire Hudson Bay drainage basin, known as Rupert's Land) to Canada in 1869 as part of the Deed of Surrender, authorized by the Rupert's Land Act 1868. At its peak, the company controlled the fur trade throughout much of the English- and later British-controlled North America. By the mid-19th century, the company evolved into a mercantile business selling a wide variety of products from furs to fine homeware in a small number of sales shops (as opposed to trading posts) acros ...

Peter Fidler
Peter Fidler (16 August 1769 – 17 December 1822) was a British surveyor, map-maker, fur trader and explorer who had a long career in the employ of the Hudson's Bay Company (HBC) in what later became Canada. He was born in Bolsover, Derbyshire, England and died at Fort Dauphin in present-day Manitoba. He married Mary (Methwewin) Mackagonne, a Cree woman, and together they had 14 children. Career Fidler joined the Hudson's Bay Company as a labourer at London and took up his post at York Factory in 1788. He was promoted to clerk and posted to Manchester House and South Branch House in what later became Saskatchewan within his first year. In 1790, he was transferred to Cumberland House and given training in surveying and astronomy by Philip Turnor who also trained David Thompson. On 23 December 1788, Thompson had seriously fractured his leg, forcing him to spend the next two winters at Cumberland House convalescing which gave Fidler the opportunity to accompany Turnor on an explo ...

Galt Museum & Archives
Galt Museum & Archives is the primary museum in Lethbridge, Alberta, Canada, and is the largest museum in the province south of Calgary. In 2006, the museum cared for a growing collection of over 20,000 artifacts and 300,000 archival documents and photographs record the history of Lethbridge and southern Alberta. It attracts over 50,000 visitors every year. History A Scientific and Historical Society was formed in Lethbridge in October 1888. Little was done for record archives, and emphasis for the society laid with the presentation of papers at bi-weekly meetings. The Gurney Museum operated out of the old Board of Trade building in Galt Gardens from 1944 until 1961 when the building was demolished.In 1944, Walter Gurney opened a private museum—the first museum in the city. The building that housed Gurney's Museum was originally built as a bandstand, no more than a platform with a railing. By 1909 several improvements had been made, and the transforming the bandstand into a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldman River
The Oldman River is a river in southern Alberta, Canada. It flows roughly west to east from the Rocky Mountains, through the communities of Fort Macleod, Lethbridge, and on to Grassy Lake, where it joins the Bow River to form the South Saskatchewan River, which eventually drains into the Hudson Bay. Oldman River has a total length of and a drainage area of . History The Oldman River was, at one time, known as the Belly River. The Belly River is now a separate river that is a tributary of the Oldman. In 1991, the Alberta government finished construction of the Oldman River Dam. The Piikani renegade, led by Milton Born With A Tooth, had attempted to divert the Oldman River away from the Lethbridge Northern Irrigation District canal intake, leading to an armed standoff. The dam was constructed where the Oldman, Crowsnest, and Castle river systems converge. 2013 floods On June 21, 2013, during the 2013 Alberta floods Alberta experienced heavy rainfall that triggered catastro ...

Lethbridge
Lethbridge ( ) is a city in the province of Alberta, Canada. With a population of 101,482 in its 2019 Alberta municipal censuses, 2019 municipal census, Lethbridge became the fourth Alberta city to surpass 100,000 people. The nearby Canadian Rockies, Canadian Rocky Mountains contribute to the city's warm summers, mild winters, and Chinook wind, windy climate. Lethbridge lies southeast of Calgary on the Oldman River. Lethbridge is the commercial, financial, transportation and industrial centre of southern Alberta. The city's economy developed from drift mining for coal in the late 19th century and agriculture in the early 20th century. Half of the workforce is employed in the health, education, retail and hospitality sectors, and the top five employers are government-based. The only university in Alberta south of Calgary is in Lethbridge, and two of the three colleges in southern Alberta have campuses in the city. Cultural venues in the city include performing art theatres, mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackfoot Confederacy
The Blackfoot Confederacy, ''Niitsitapi'' or ''Siksikaitsitapi'' (ᖹᐟᒧᐧᒣᑯ, meaning "the people" or " Blackfoot-speaking real people"), is a historic collective name for linguistically related groups that make up the Blackfoot or Blackfeet people: the ''Siksika'' ("Blackfoot"), the '' Kainai or Blood'' ("Many Chiefs"), and two sections of the Peigan or Piikani ("Splotchy Robe") – the Northern Piikani (''Aapátohsipikáni'') and the Southern Piikani (''Amskapi Piikani'' or ''Pikuni''). Broader definitions include groups such as the ''Tsúùtínà'' ( Sarcee) and ''A'aninin'' (Gros Ventre) who spoke quite different languages but allied with or joined the Blackfoot Confederacy. Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region. They followed the bison herds as they mig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Impact Assessment
Environmental Impact assessment (EIA) is the assessment of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term " strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. It is a tool of environmental management forming a part of project approval and decision-making. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review. The purpose of the assessment is to ensure that decision makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Reclamation
Mine reclamation is the process of modifying land that has been mined to ecologically functional or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started. Mine reclamation creates useful landscapes that meet a variety of goals ranging from the restoration of productive ecosystems to the creation of industrial and municipal resources. In the United States, mine reclamation is a regular part of modern mining practices. Modern mine reclamation reduces the environmental effects of mining. Reclamation processes As part of the life cycle of a surface coal mine, completed mine areas must undergo rehabilitation. When mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a “higher and better” post-mining land use (PMLU) that has been approved as part of the original mi ...

Strip-mining
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. In North America, where the majority of surface coal mining occurs, this method began to be used in the mid-16th century and is practiced throughout the world in the mining of many different minerals. In North America, surface mining gained popularity throughout the 20th century, and surface mines now produce most of the coal mined in the United States. In most forms of surface mining, heavy equipment, such as earthmovers, first remove the overburden. Next, large machines, such as dragline excavators or bucket-wheel excavators, extract the mineral. The pros of surface mining are that it has a lower financial cost and is a lot safer than undergrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
