Mount Robertson
Mount Robertson is a mountain in the Canadian Rockies, standing astride the British Columbia-Alberta boundary between Palliser Pass and North Kananaskis Pass. The British Columbia side of the pass is in Mount Assiniboine Provincial Park. The mountain is named for Sir William Robertson (1860–1933), 1st Baronet, Chief of the Imperial General Staff from 1916 to 1918 during the First World War. Geology Mount Robertson is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny. The Haig Glacier, largest singular glacier in Kananaskis Country, lies to the south of the peak. Climate Based on the Köppen climate classification, Mount Robertson is located in a subarctic climate with cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. See also * List of peaks on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Sir Douglas
Mount Sir Douglas is located on the border of Alberta and British Columbia on the Continental Divide, at the northern end of Height of the Rockies Provincial Park and east of Invermere. It is Alberta's 18th highest peak, and 28th prominence mountain as well as British Columbia's 28th highest peak. It was named in 1916 by interprovincial boundary surveyors after Field Marshal Sir Douglas Haig. Geology Mount Sir Douglas is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.

Chief Of The Imperial General Staff
The Chief of the General Staff (CGS) has been the title of the professional head of the British Army since 1964. The CGS is a member of both the Chiefs of Staff Committee and the Army Board. Prior to 1964, the title was Chief of the Imperial General Staff (CIGS). Since 1959, the post has been immediately subordinate to the Chief of the Defence Staff, the post held by the professional head of the British Armed Forces. The current Chief of the General Staff is General Sir Patrick Sanders, who succeeded his predecessor, General Sir Mark Carleton-Smith, in June 2022. Background The title was also used for five years between the demise of the Commander-in-Chief of the Forces in 1904 and the introduction of Chief of the Imperial General Staff in 1909. The post was then held by General Sir Neville Lyttelton and, briefly, by Field Marshal Sir William Nicholson. Throughout the existence of the post the Chief of the General Staff has been the First Military Member of the Army Boar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-thousanders Of British Columbia
Three-thousanders are mountains with a height of between , but less than above sea level. Similar terms are commonly used for mountains of other height brackets e. g. four-thousanders or eight-thousanders. In Britain, the term may refer to mountains above . Climatological significance In temperate latitudes three-thousanders play an important role, because even in summer they lie below the zero degree line for weeks. Thus the chains of three-thousanders always form important climatic divides and support glaciation - in the Alps the contour is roughly the general limit of the "nival step"; only a few glaciated mountains are under (the Dachstein, the easternmost glaciated mountain in the Alps, is, at , not a three-thousander). In the Mediterranean, however, the three-thousanders remain free of ice and, in the tropics, they are almost insignificant from a climatic perspective; here the snow line lies at around to , and in the dry continental areas (Trans-Himalayas, Ande ...

List Of Peaks On The Alberta–British Columbia Border
This is a list of peaks on the Alberta–British Columbia border, being the spine of the Continental Divide from the Canada–United States border to the 120th meridian, which is where the boundary departs the Continental Divide and goes due north to the 60th parallel. Peaks are listed from north to south and include the four peaks not on the Continental Divide but which are on the 120th Meridian, stretching approximately due north from Intersection Mountain, which as its name implies is located at the intersection of the Divide and the Meridian.

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] |
Kananaskis Country
Kananaskis Country is a multi-use area west of Calgary, Alberta, Canada in the foothills and front ranges of the Canadian Rockies. The area is named for the Kananaskis River, which was named by John Palliser in 1858 after a Cree acquaintance. Covering an area of approximately , Kananaskis Country was formed by the Alberta Government in 1978 to provide an assortment of land uses and designations. Land uses include resource extraction activities (such as forestry, cattle grazing, water, oil and gas), recreation, power generation, and residential communities. Land designations include public land and protected areas. Administration and purpose The area, which now includes Kananaskis Country, has been administered since 1945 as Improvement District No. 5 (Kananaskis). It was established by the Municipal Affairs branch of the Alberta Government for multiple uses including logging, gas and oil extraction, cattle grazing, recreation and tourism.

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.

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
