Pinnacle Mountain (Alberta)
Pinnacle Mountain is a mountain summit in Banff National Park in Alberta, Canada. It's part of the Bow Range, which is a sub-range of the Canadian Rockies. The nearest higher peak is Eiffel Peak, to the southwest. Mount Temple is situated immediately northeast of Pinnacle Mountain, with Sentinel Pass as the low point between the two. History The peak was named in 1894 by Walter Wilcox because of large pinnacles on the mountain near Sentinel Pass. Wilcox wrote of the pinnacles in his 1896 book, "Camping in the Canadian Rockies": ''"The limestone strata of this mountain were nearly perfectly horizontal, and had been sculptured by rain and frost into an endless variety of minarets, spires, and pinnacles. These, crowning the summits of ridges and slopes with ever changing angles, as though they represented alternating walls and roofs of some great cathedral, all contributed to give this mountain, with its elegant contours and outlines, the most artistically perfect assemblage of ...

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.

Mount Hungabee
Mount Hungabee, officially Hungabee Mountain, is a mountain located on the boundaries of Banff National Park and Yoho National Park on the Continental Divide at the head of Paradise Valley, in Canada. The peak was named in 1894 by Samuel Allen after the Stoney Indian (also known as Nakoda) word for "chieftain" as the mountain is higher than its neighbouring peaks. The mountain can be seen from the Icefields Parkway (#93) in the upper Bow Valley. Climbing ;History Mt. Hungabee was first climbed in 1903 by H.C. Parker who was guided by Hans Kaufmann and Christian Kaufmann. ;Routes The normal climbing route is via the west ridge (III 5.4) which features route finding challenges. Early summer is not recommended due to avalanche hazard from snow on the NW face. Geology Mount Hungabee 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 Lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tuzo
Mount Tuzo, previously "Peak Seven" or "Shagowa", was named in 1907 after its first ascendant Henrietta L. Tuzo. It is located within the Valley of the Ten Peaks in the Canadian Rockies, along the Continental Divide, which forms the boundary between British Columbia and Alberta in this region. __NOTOC__ Geology Like other mountains in Banff Park, Mount Tuzo is composed of sedimentary rock laid down from 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. Climate Based on the Köppen climate classification, Mount Tuzo is located in a subarctic climate zone with cold, snowy winters, and mild summers. Temperatures can drop below -20 C with wind chill factors below -30 C.

Valley Of The Ten Peaks
Valley of the Ten Peaks (french: Vallée des Dix Pics) is a valley in Banff National Park in Alberta, Canada, which is crowned by ten notable peaks and also includes Moraine Lake. The valley can be reached by following the Moraine Lake road near Lake Louise. The ten peaks were originally named by Samuel Allen, an early explorer of the region, who simply referred to them by using the numerals from one to ten in the Stoney First Nations Language. He may have learned the terms from his Native American guides, who helped him with the horses. The Nakoda–also known as the Stoney Indians–is a tribe whose culture and dialect are closely related to that of the Assiniboine First Nation, from whom they are believed to have separated in the mid-1700s, and who roamed large parts of the prairies and mountains of western Alberta well into British Columbia. The secluded Valley of the Ten Peaks was part of their original homeland. Gradually, though, all but three of the mountains were rename ...

Moraine Lake
Moraine Lake is a glacially fed lake in Banff National Park, outside the hamlet of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of approximately . The lake has a surface area of . The lake, being glacially fed, does not reach its crest until middle to late June. When it is full, it reflects a distinctive shade of azure blue. The unique colour is due to the refraction of light off the rock flour deposited in the lake on a continual basis by surrounding glaciers. Tourism Hiking trails The area around the lake has several walking/hiking trails that are, from time to time, restricted. The trail most commonly taken by tourists is The Rockpile Trail, which is along the actual moraine. The trail is approximately long, with an elevation change of . The view of the lake from the top of the rockpile is one of the most photographed locations in all of Canada. That view of the mountains behind the lake in Valley of the Ten Peaks is known ...

Mount Aberdeen (Alberta)
Mount Aberdeen is a mountain summit located in the Lake Louise area of Banff National Park, in the Canadian Rockies of Alberta, Canada. Its nearest higher peak is Mount Lefroy, to the southwest. Haddo Peak is on the same massif with Mount Aberdeen, and the Aberdeen Glacier is between the two peaks. __NOTOC__ History Mount Aberdeen was named by James J. McArthur in 1897 for Lord Aberdeen, 7th Governor General of Canada. Prior to 1897 it was known as Hazel Peak, but there is no record of who Hazel was. The first ascent of the peak was made in 1894 by Samuel E.S. Allen, L.F. Frissel, and Walter D. Wilcox. In 1917, V.A. Flynn reached the summit by traversing from the top of Haddo Peak with a descent to the Aberdeen Glacier and then up over steep snow and an ice arête. The mountain's name was made official in 1952 by the Geographical Names Board of Canada.

Geology Of The Rocky Mountains
The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins. Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising the Rocky Mountains. Subsequent erosion by glaciers has created the ...

Geology Of Alberta
The geology of Alberta encompasses parts of the Canadian Rockies and thick sedimentary sequences, bearing coal, oil and natural gas, atop complex Precambrian crystalline basement rock. Geologic history, stratigraphy & tectonics The Precambrian granite and gneiss crystalline basement rocks beneath Alberta are extremely ancient, dating to the Archean and Proterozoic. The Slave Craton and Southern Alberta craton are the oldest units at more 2.5 billion years old, while younger units from the Proterozoic include the Wopmay orogeny, Great Slave Lake shear zone, Pre-Taltston basement, Taltson magmatic zone, Athabasca polymetamorphic terrane, Red Earth granulite domain, Kimiwan isotopic anomaly, Ksituan magmatic arc, Virgin River shear zone, Central Alberta intrusions and Lacombe domain. In many cases, Proterozoic deformation overprinted older Archean rocks. The Hudsonian Orogeny from 1.9 to 1.6 billion years ago was the last major regional metamorphic event.

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 ...

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] |
