Mount Kerkeslin
__NOTOC__ Mount Kerkeslin is a mountain summit located in the Athabasca River valley of Jasper National Park, in the Canadian Rockies of Alberta, Canada. It is the highest peak of the Maligne Range. It is located in the south part of the Maligne Range, east of the Icefields Parkway and is visible from the Athabasca Falls lookout. Mount Kerkeslin is composed of sedimentary rock laid down during the Cambrian period and pushed east and over the top of younger rock during the Laramide orogeny. The mountain was named in 1859 by James Hector during the Palliser expedition but the source of the name is not known. Climate Based on the Köppen climate classification, Mount Kerkeslin 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. Precipitation runoff from Mount Kerkeslin drains into the Athabasca River.

Athabasca Falls
Athabasca Falls is a waterfall in Jasper National Park on the upper Athabasca River, approximately south of the townsite of Jasper, Alberta, Canada, and just west of the Icefields Parkway. Geography and geology Athabasca Falls is a Class 5 waterfall, with a total drop height of and a width of . A powerful, picturesque waterfall, Athabasca Falls is not known so much for its height as for its force, due to the large quantity of water falling into the gorge, which can be substantial even on a cold morning in the fall, when river levels tend to be at their lowest. The river falls over a layer of hard quartzite and through the softer limestone below, carving a short gorge and a number of potholes. Access The falls can be safely viewed and photographed from various viewing platforms and walking trails around the falls. Access is from the nearby parking lot, which leads off Highway 93A just northeast of the falls. Highway 93A takes off from the nearby Icefields Parkway, and crosses ...

Cambrian
The Cambrian Period ( ; sometimes symbolized C with bar, Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established as "Cambrian series" by Adam Sedgwick, who named it after Cambria, the Latin name for 'Cymru' (Wales), where Britain's Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large "Transition Series", although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-thousanders Of Alberta
Two-thousanders are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: ''Zweitausender''). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain. The Säuling (top) is a prominent, individual peak, whereas the Schneeberg (bottom) is an elongated limestone massif. In ranges like the Allgäu Alps, the Gesäuse or the Styrian-Lower Austrian Limestone Alps the mountain tour descriptions for mountaineers or hikers commonly include the two-thousanders, especially in areas where only a few summits exceed this level. Examples from these regions of the Eastern Alps Eastern Alps is the name given to the eastern half of the Alps, usually defined as the area east of a line from Lake Constance and the Alpine Rhine valley up to the Splügen Pass at the Alpine divide and down the Liro River to Lake Como in the ...

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 ...

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] |
James Hector
Sir James Hector (16 March 1834 – 6 November 1907) was a Scottish-New Zealand geologist, naturalist, and surgeon who accompanied the Palliser Expedition as a surgeon and geologist. He went on to have a lengthy career as a government employed man of science in New Zealand, and during this period he dominated the Colony's scientific institutions in a way that no single man has since. Early life He was born at 11 Danube Street in Stockbridge, Edinburgh the son of Alexander Hector WS and his wife, Margaret Macrostie. He attended the Edinburgh Academy from 1844 to 1845. At 14, he began articles as an actuary at his father's office. He joined University of Edinburgh as a medical student and received his medical degree in 1856 at the age of 22. Palliser expedition Shortly after receiving his medical degree, upon the recommendation of Sir Roderick Murchison – director-general of the British Geological Survey – Hector was appointed geologist on the Palliser Expedition under ...

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 ...

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] |
