Mount Sparrowhawk
Mount Sparrowhawk is a mountain summit located in Kananaskis Country in the Canadian Rockies of Alberta, Canada. Mount Sparrowhawk's nearest higher peak is Mount Bogart, to the southeast. Sparrowhawk's south slope was a candidate to be used as a ski hill for the alpine events at the 1988 Winter Olympics, but nearby Mount Allan's Nakiska was selected instead. History Mount Sparrowhawk was named in 1917 for , a British destroyer that sank during the Battle of Jutland in World War I. This mountain's name was officially adopted in 1922 by the Geographical Names Board of Canada. The first ascent of the peak was made in 1947 by R.C. Hind, L. Parker, Mr. and Mrs. H.H. Rans. Mount Shark and Mount Sparrowhawk were designated as sites to host alpine skiing events in Calgary's bid for the 1988 Winter Olympics, however, the venue for the alpine skiing events moved to Nakiska shortly after Calgary was awarded the Games.

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 ...

Bow River
The Bow River is a river in Alberta, Canada. It begins within the Canadian Rocky Mountains and winds through the Alberta foothills onto the prairies, where it meets the Oldman River, the two then forming the South Saskatchewan River. These waters ultimately flow through the Nelson River into Hudson Bay. The Bow River runs through the city of Calgary, taking in the Elbow River at the historic site of Fort Calgary near downtown. The Bow River pathway, developed along the river's banks, is considered a part of Calgary's self-image. First Nations made varied use of the river for sustenance before settlers of European origin arrived, such as using its valleys in the buffalo hunt. The name ''Bow ''refers to the reeds that grew along its banks and were used by the First Nations to make bows; the Blackfoot language name for the river is , meaning "river where bow reeds grow". The river is an important source of water for irrigation and drinking water. Between the years 1910 and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spray Lakes Reservoir
Spray Lakes Reservoir is a reservoir in Alberta, Canada. The Spray Lakes were a string of lakes formed along the Spray River, a tributary of the Bow River. With the damming of the river, the lakes were united in the Spray Lakes Reservoir. It lies between the Goat Range and the Three Sisters ridge, at an elevation of . The lake is followed by Highway 742 (Smith-Dorrien Trail) in the northern part. The Lake is impounded by two embankment dams; the 28-metre-high ''Canyon Dam'' is located near the southern end of the reservoir and blocks the main outlet of the river in a north-northwestern direction, while the secondary 13-metre-high ''Three Sisters Dam'' at the northern end of the reservoir provides the outlet for the diverted water way and contains a small 3 MW powerhouse. The two dams and the lake were created in 1951 as part of the Spray Hydro Electric Project. From the Three Sisters Dam the water is diverted into a secondary reservoir known as the ''Goat Pond'' which direc ... [...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] |
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.
