Abraham Mountain
Abraham Mountain is a mountain summit located in the North Saskatchewan River valley of the Canadian Rockies of Alberta, Canada. Its nearest higher peak is Allstones Peak, to the west. Abraham Mountain can be seen from David Thompson Highway and Abraham Lake. Precipitation runoff from Abraham Mountain drains east into Abraham Lake. History Like the lake, the mountain was named for Silas Abraham (1871–1961), a Stoney Indian inhabitant of the Kootenay Plains and Saskatchewan River valley, who was employed by Mary Schäffer as her guide during her 1906 and 1907 explorations.The David Thompson Highway Hiking Guide – 2nd Edition by Jane Ross, Daniel Kyba.

Canadian Rockies
The Canadian Rockies (french: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico. Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system).

Mary Schäffer Warren
Mary Schäffer Warren (1861–1939) was an American-Canadian naturalist, illustrator, photographer, and writer. She was known for her experiences in the Canadian Rockies in the early 20th century. Biography Warren was born Mary Townsend Sharples in 1861 in West Chester, Pennsylvania. She studied flower painting with George Cochran Lambdin. In 1889 Sharples embarked on her first visit to the Canadian Rockies, accompanied by her fellow art student, Mary Vaux. In 1890 she married Dr. Charles Schäffer, an amateur botanist, whom she had met the previous year at Glacier House, the Canadian Pacific Railway's hotel in the Selkirk Mountains. The couple would spend summers and autumns traveling in the Canadian Rockies. Their winters were spent in Philadelphia. Charles Schäffer died in 1903, as did Mary's father and mother. In 1904, Schäffer returned to the Canadian Rockies with her friend Mary "Mollie" Adams determined to complete a botanical guide that her husband had started. To co ...

Geography Of Alberta
Alberta is one of the thirteen provinces and territories of Canada. Located in Western Canada, the province has an area of and is bounded to the south by the United States state of Montana along 49° north for ; to the east at 110° west by the province of Saskatchewan for ; and at 60° north the Northwest Territories for . The southern half of the province borders British Columbia along the Continental Divide of the Americas on the peaks of the Rocky Mountains, while the northern half borders British Columbia along the 120th meridian west. Along with Saskatchewan it is one of only two landlocked provinces or territories. Terrain Alberta's landscape is marked by the impact of the Wisconsin Glaciation, about 75,000 to 11,000 years ago, when the entire future province was covered in ice. As the ice sheet receded, the landscape was changed, and large amounts of glacial till were left behind. The southern portion consists chiefly of plains that are almost entirely treeless. As ...

Geology Of The Rocky Mountains
The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins. Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising the Rocky Mountains. Subsequent erosion by glaciers has created the ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laramide Orogeny
The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute. The Laramide orogeny occurred in a series of pulses, with quiescent phases intervening. The major feature that was created by this orogeny was deep-seated, thick-skinned deformation, with evidence of this orogeny found from Canada to northern Mexico, with the easternmost extent of the mountain-building represented by the Black Hills of South Dakota. The phenomenon is named for the Laramie Mountains of eastern Wyoming. The Laramide orogeny is sometimes confused with the Sevier orogeny, which partially overlapped in time and space. The orogeny is commonly attributed to events off the west coast of North America, where the Kula Plate, Kula and Farallon Plates were sliding under the North American plate. Most hypothes ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Martin Nordegg
Martin Nordegg (; né Cohn) (18 July 1868 – 13 September 1948) was a German entrepreneur, pioneer, and founder of the community of Nordegg, Alberta. Early life The son of Moritz Cohn, a Jewish rabbi, and Auguste Cohn, Martin Cohn was born in Reichenbach, Silesia (current-day Dzierżoniów, Poland), which was then part of the North German Confederation. He received a classical education before joining the military. He was discharged in 1894 after suffering an injury to his arm. Moving to Berlin, Martin studied photochemistry under the direction of Professor Hermann Wilhelm Vogel at the Gewerbe Institut. Berlin years Martin began working for Georg W. Büxenstein at the Georg Büxenstein & Company Photochemigraphical Institute, a printing firm. The two men would eventually become close business partners.

Stoney Indian
The Nakoda (also known as Stoney or ) are an Indigenous people in Western Canada and, originally, the United States. They used to inhabit large parts of what is now Alberta, Saskatchewan and Montana, but their reserves are now located in Alberta and in Saskatchewan, where they are scarcely differentiated from the Assiniboine. Through their language they are related to the Dakota and Lakota nations of the Great Plains and the Rocky Mountains, part of the large Sioux Nation. They refer to themselves in their own language as " Nakoda", meaning ''friend'', ''ally''. The name "Stoney" was given them by white explorers, because of their technique of using fire-heated rocks to boil broth in rawhide bowls. They are very closely related to the Assiniboine, who are also known as ''Stone Sioux'' (from the Ojibwe ). Alberta's Nakoda First Nation comprises three bands: Bearspaw, Chiniki and Wesley. The Stoney were "excluded" from Banff National Park between 1890 and 1920. In 2010 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
