Mount Jerram
Mount Jerram is a mountain summit located in the Opal Range of the Canadian Rockies of Alberta, Canada. Its nearest higher peak is Elpoca Mountain, to the south-southeast. Mount Jerram is situated east of Mount Wintour, within Peter Lougheed Provincial Park. Like so many of the mountains in Kananaskis Country, Mount Jerram received its name from the persons and ships involved in the 1916 Battle of Jutland, the only major sea battle of the First World War. History The mountain was named in honor of Admiral Sir Thomas Henry Martyn Jerram (1858-1933), Royal Navy commander of the Second Battle Squadron during the Battle of Jutland in World War I. The mountain's name was made official in 1922 by the Geographical Names Board of Canada. The first ascent of the peak was made on June 15, 1957 by Jim Tarrant and Don Morrison. Geology Mount Jerram is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Mountains Of Alberta
Most of Alberta's mountains are found on the western edge of the province of Alberta, consisting of the eastern slopes of the Canadian Rockies, which run through the province from Alberta's mid-point to its southern border with the United States. Other elevated spots can be found in the Caribou Mountains and the Cypress Hills. The peaks of the Canadian Rockies are majestic, many of them reaching a height of more than three kilometres above sea level. Alberta's southwestern boundary is traced on the Continental Divide, along the high ranges of the Rocky Mountains, and many peaks are located on the Alberta–British Columbia border. The peak of Mount Columbia, within Jasper National Park, is the highest point in Alberta, second highest in the Canadian Rockies and 28th highest in Canada. The Caribou Mountains are located in the northern extremity of Alberta, forming an elevated plateau in the northern plains and wetlands. They reach an altitude of 1,030 m, almost 700&n ...

Elbow River
The Elbow River is a river in southern Alberta, Canada. It flows from the Canadian Rockies to the city of Calgary, where it merges into the Bow River. Course The Elbow River originates at Elbow Lake in the Front Range of the Canadian Rocky Mountains of southwestern Alberta draining a watershed of 1235 km2. The river extends from a largely forested headwater region through alpine, sub-alpine, boreal foothills, and aspen parkland ecoregions, to a predominantly agricultural mid-region of improved pasture with dispersed cattle grazing and accompanying forage crop production, and thereafter through the city of Calgary under the influence of the urban environment. The river has a total length of , and drains an area of over . From its origin in the Elbow Pass at approximately , it drops at a 1 percent slope to its mouth at the Bow River, at an elevation of . The Elbow River originates from Elbow Lake in the Elbow-Sheep Wildland Provincial Park in the Canadian Rockies, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kananaskis River
The Kananaskis River is a mountain river in western Alberta, Canada. It is a tributary of the Bow River, crossing the length of Kananaskis Country. The river was named by John Palliser in 1858 after a Cree. Course The Kananaskis originates in the Canadian Rockies, east of the continental divide, in Peter Lougheed Provincial Park. It flows southeast to the Upper Kananaskis Lake, then turns north into the Lower Kananaskis Lake. From here it has a northbound course on the border of Spray Valley Provincial Park and Elbow-Sheep Wildland Provincial Park, where the Kananaskis Trail follows its itinerary. The lower course flows through Bow Valley Provincial Park, where Barrier Lake is formed along the river. Barrier Lake is an artificial lake used for hydroelectric power generation. The Kananaskis merges into the Bow River at Seebe, 30 km east of Canmore. The Kananaskis River has a total length of . The river contains three hydroelectric dams, each of which contains a powerhous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Lewis Overthrust
The Lewis Overthrust is a geologic thrust fault structure of the Rocky Mountains found within the bordering national parks of Glacier in Montana, United States and Waterton Lakes in Alberta, Canada. The structure was created due to the collision of tectonic plates about 170 million years ago that drove a several mile thick wedge of rock eastwards, causing it to overlie softer Cretaceous age rock that is 400 to 500 million years younger. Geography The Canadian Rocky Mountain foreland thrust and fold belt is a northeastward tapering deformational belt consisting of Mesoproterozoic, Paleozoic, and Mesozoic strata. The Lewis thrust sheet is one of the major structures of the foreland thrust and fold belt extending over from Mount Kidd near Calgary, AB in the Southeast Canadian Cordillera to Steamboat Mountain, located west of Great Falls, Northwest Montana in the United States. The Lewis overthrust provides scientific insight into geologic processes happening in other parts of t ... [...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.
