Mount Lyell (Canada)
Mount Lyell is a mountain on the Alberta–British Columbia border in western Canada. Comprising five distinct summits, Mount Lyell reaches a height of . The mountain was named by James Hector in 1858 in recognition of Scottish geologist Sir Charles Lyell. __NOTOC__ Geography Mount Lyell is located on the Great Divide, which forms the BC-Alberta boundary in this area, in Banff National Park. Collectively, the five peaks, and the Mt. Lyell massif itself, are commonly referred to as 'the Lyells'. The mountain is the highest in the Lyell Group, a subrange of the Central Icefields in the Canadian Rockies. In 1972, five distinct peaks on Mt. Lyell (formerly referred to as only Lyell 1 through 5 or L1 through L5), were named after Swiss mountain guides who settled in Golden, British Columbia in 1912. Running south to north along the interprovincial boundary, these peaks are: Christian Peak (L5), Walter Peak (L4), and Ernest Peak (L3), named after Christian Hässler, Walter Feuz ...

Mount Forbes
Mount Forbes is the seventh tallest mountain in the Canadian Rockies and the tallest within the boundaries of Banff National Park. It is located in southwestern Alberta, southwest of the Saskatchewan River Crossing in Banff. The mountain was named by James Hector in 1859 after Edward Forbes, Hector's natural history professor at the University of Edinburgh during the mid-19th century. Mount Forbes was first ascended on August 10, 1902, by the Swiss brothers Christian and Hans Kaufmann, guiding the British gentlemen J. Norman Collie, James Outram, Hugh E.M. Stutfield, George M. Weed, and Herman Woolley. The shark tooth-shaped peak can be "predominantly seen from many parts of the range. The normal route, the NW face and the N Ridge all are well worth climbing." __NOTOC__ Climbing routes There are several climbing routes for Mount Forbes, including: * West Ridge (Normal Route) III * North-West Face Variation III * West Ridge of Rosita III 5.3 The most common approach ro ...

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 and Farallon Plates were sliding under the North American plate. Most hypotheses propos ...

Jurassic
The Jurassic ( ) is a geologic period and 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 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. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

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.

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] |
Columbia River
The Columbia River ( Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Saskatchewan River
The South Saskatchewan River is a major river in Canada that flows through the provinces of Alberta and Saskatchewan. For the first half of the 20th century, the South Saskatchewan would completely freeze over during winter, creating spectacular ice breaks and dangerous conditions in Saskatoon, Medicine Hat and elsewhere. At least one bridge in Saskatoon was destroyed by ice carried by the river. The construction of the Gardiner Dam in the 1960s, however, lessened the power of the river by diverting a substantial portion of the South Saskatchewan's natural flow into the Qu'Appelle River. By the 1980s many permanent sandbars had formed due to the lowering of the level of the river. From the headwaters of the Bow River, the South Saskatchewan flows for . At its mouth at Saskatchewan River Forks, it has an average discharge of and has a watershed of , 1,800 of which are in Montana in the United States and in Alberta and Saskatchewan. Course The river originates at the confluence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ernest Peak
Ernest Peak - Lyell 3, L3 or Mt. Lyell (on maps, etc.) - is the central and highest peak of five distinct subpeaks on Mount Lyell (Canada) and is located on the border of Alberta and British Columbia. (There has been some dispute whether Lyell 2 or Lyell 3 is highest, but according to the recently released and corrected Climbers Guide to The Canadian Rocky Mountains - Rockies West book, the tallest is Ernest Peak). It was named in 1972 by Sydney R. Vallance after Ernest Feuz Jr. __NOTOC__ Geology and climate Due to this peak being the central and tallest subpeak - and thus ''is'' "Mount Lyell" - see the Mount Lyell article for geology and climate.

Walter Peak (Canada)
__NOTOC__ Walter Peak - Lyell 4 or L4 - is the fourth highest of five distinct subpeaks on Mount Lyell, three of which are located on the border of Alberta and British Columbia (Christian, Walter and Ernest Peaks). It was named in 1972 by Sydney R. Vallance after Walter Feuz, an early mountain guide in the Rockies. "Walter Feuz (1894-1986) never took out an official guide's license since he was underage when he left his family home in Interlaken, CH, but was trained up for the work by his older brothers, Edward, Jr. and Ernest."" Geology and climate Due to the close proximity of this peak to the central and highest peak (0.6 km (0.4 mi)), see Mount Lyell for geology and climate.
