Lectern Peak
Lectern Peak is a mountain summit located in Alberta, Canada. Description Lectern Peak is set within Jasper National Park, in the Trident Range of the Canadian Rockies. The town of Jasper, Alberta, Jasper is situated to the north and the Continental Divide is to the west. The nearest higher neighbor is Aquila Mountain (Alberta), Aquila Mountain, to the south. The peak is visible from the Icefields Parkway to the east. Precipitation Surface runoff, runoff from Lectern Peak drains into Portal Creek and Astoria River which are both tributaries of the Athabasca River. Topographic relief is significant as the summit rises 900 meters (2,950 feet) above the creek in two kilometers (1.2 mile). A partial ascent of the mountain was made in 1913 by Geoffrey E. Howard who named the peak for its resemblance to a church lectern.Howard Palmer, James Monroe Thorington (1921), ''A Climber's Guide to the Rocky Mountains of Canada'', American Alpine Club, p. 151 He was accompanied ...

Geographical Names Board Of Canada
The Geographical Names Board of Canada (GNBC) is a national committee with a secretariat in Natural Resources Canada, part of the Government of Canada, which authorizes the names used and name changes on official federal government maps of Canada. History It was created in December 1897, by Order in Council, as the Geographic Board of Canada. It consisted of one Board member from each of four Government of Canada departments, as well as the Surveyor General of Dominion Lands, while a secretariat was provided by the then-extant Department of the Interior. In December 1899, the Order in Council was amended to give the Canadian provinces and territories the right to nominate one official, each, to be a Board member. The board was succeeded by the Canadian Board on Geographic Names in 1948, then reorganized as the Canadian Permanent Committee on Geographic Names (CPCGN) in 1961. Structure , the Board consists of 27 members, one from each of the provinces and territories, and ot ... [...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 are: * the striking Nebelhorn (2,224 m) near Oberstdorf or the Säuling (2,047 m) near Neuschwanstein, * the Admonter Reichenstein (2,251 m), Eisenerzer Reichenstein (2,165 m), Großer Pyhrgas (2,244 m) or Hochtor ( ...

Terminal Mountain
Terminal Mountain is a mountain summit located in Jasper National Park, in the Trident Range of the Canadian Rockies of Alberta, Canada. The town of Jasper is situated 12 kilometers to the north-northeast. Terminal Mountain forms the west buttress of Marmot Pass, and the east buttress is formed by Marmot Mountain, home of the Marmot Basin alpine ski area. Peveril Peak rises to the south across Circus Valley, and the north side towers above the valley of Whistlers Creek. The nearest higher neighbor is Manx Peak, to the west. History The descriptive name ''Terminal'' was applied in 1916 by Morrison P. Bridgland (1878-1948), a Dominion Land Surveyor who named many peaks in Jasper Park and the Canadian Rockies. It appeared as ''Mt. Terminal'', 9300 feet, in a 1921 book, "''A Climber's Guide to the Rocky Mountains of Canada.''" The mountain's present toponym was officially adopted in 1951 by the Geographical Names Board of Canada. Climate Based on the Köppen climate classificat ...

Peveril Peak
Peveril Peak is a mountain summit located in Alberta, Canada. Description Peveril Peak is set within Jasper National Park, in the Trident Range of the Canadian Rockies. The town of Jasper is situated to the north and the Continental Divide is to the west. The nearest higher neighbor is Terminal Mountain, to the north. The peak is visible from the Icefields Parkway to the east. Precipitation runoff from Peveril Peak drains into Portal Creek, a tributary of the Athabasca River. Topographic relief is significant as the summit rises 850 meters (2,790 feet) above the creek in one kilometer (0.6 mile). History The summit was first reached in 1926 by Bradley B. Gilman and his crew, who called it "Portal Peak."''The American Alpine News'' Issues 176-199 (1986), American Alpine Club, p. 17. The peak was named in 1932 after Sir Walter Scott's 1823 novel ''Peveril of the Peak'', and in turn the title refers to Peveril Castle. The mountain's toponym was officially adopte ...

Chak Peak
Chak Peak is a mountain summit located in the Athabasca River valley of Jasper National Park, in the Canadian Rockies of Alberta, Canada. Chak is a name derived from the Stoney language meaning "eagle". Precipitation runoff from Chak Peak drains into Portal Creek and Astoria River which are both tributaries of the Athabasca River. __NOTOC__ Climate Based on the Köppen climate classification, Chak Peak 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. Geology The mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods and pushed east and over the top of younger rock during the Laramide orogeny.

Marmot Mountain
Marmot Mountain is a mountain summit located in Alberta, Canada. Description Marmot Mountain is set within Jasper National Park, in the Trident Range of the Canadian Rockies. The town of Jasper is situated to the north and the Continental Divide is to the west. The nearest higher neighbor is Terminal Mountain, to the southwest. Precipitation runoff from Marmot Mountain drains into Portal Creek and Whistlers Creek which are both tributaries of the Athabasca River. Topographic relief is modest as the summit rises 1,550 meters (5,085 feet) above the Athabasca Valley in six kilometers (3.7 miles). The mountain was named in 1916 and the toponym was officially adopted February 7, 1951, by the Geographical Names Board of Canada. The name refers to the marmot, which are large ground squirrels which inhabit the slopes. The Whistlers, Siffleur Mountain and Arctomys Peak also owe their names to the marmot, an indication that the animal was a favorite of the early expl ...

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. ...

Line Parent
A peak's line parent is the closest higher peak on the highest ridge leading away from the peak's "key col". A col is the lowest point on the ridge between two summits and is roughly synonymous with pass, gap, saddle and notch. The highest col of a peak is its key col. If there is more than one ridge which can be followed to a higher peak then the line parent is the peak closest to the key col. Usually, a line parent must meet some prominence criteria, which might vary depending on the author and the location of the peak. There are at least two other kinds of peak parentage: island parentage, which is also referred to as encirclement or topographic parentage, and source parentage. See also * Topographic prominence In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling ...

Laramide Orogeny
The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 80 to 70 million years ago, and ended 55 to 35 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 and Farallon Plates were sliding under the North American Plate. Most hypotheses propo ...

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 143.1 Mya. The Jurassic constitutes the second and middle period of the Mesozoic, Mesozoic Era as well as the eighth period of the Phanerozoic, Phanerozoic Eon 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 (CAMP). The beginning of the Toarcian Age started around 183 million years ago and is marked by the Toarcian Oceanic Anoxic Event, a global episode of Anoxic event, oceanic anoxia, ocean acidification, and elevated global temperatures associated with extinctions, likely caused by the eruption of the Kar ...

Precambrian
The Precambrian ( ; or pre-Cambrian, sometimes abbreviated pC, 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 Latinized 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.
