Mount Rhondda
Mount Rhondda is located on the Continental Divide straddling the Canadian provinces of Alberta and British Columbia. It was named in 1917 by the Interprovincial Boundary Survey after David Alfred Thomas, First Viscount Baron Rhondda. __NOTOC__ First Ascent Mt. Rhondda was first climbed in August 1923 by A. Geoffrion, J.W.A. Hickson and Edward Feuz Jr. The party's original intent was the FA of Mount Baker but early on in the ascent they discovered tracks from a different party (Walter Wilcox and Rudolf Aemmer) heading towards Mt. Baker. They decided to continue onto the col between the two peaks where they spotted snow tracks and cairn on the summit rocks of Mt. Baker. With Baker claimed, they turned their attention to Mt. Rhondda which they summitted in the early afternoon after ascending mixed terrain of rock and snow. Geology Mount Rhondda is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pu ...

Waputik Mountains
The Waputik Mountains are a mountain range of the Canadian Rockies, located on the Continental Divide between Banff and Yoho National Park. Covering an area of , the range is located west of the Howse, Blaeberry and Amiskwi Rivers and east of the Bow and Mistaya Rivers and south to Kicking Horse Pass. Named in 1884 by George M. Dawson, "waputik" is the Stoney Indian word for white goat. Many of the highest peaks of the range are heavily glaciated as they sit within the Waputik and Wapta Icefields. The range is further divided into the President Range and Waputik Range This range includes the following mountains and peaks: See also * Ranges of the Canadian Rockies The Canadian Rockies are a segment of the North American Rocky Mountains found in the Canadian provinces of Alberta and British Columbia.

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 precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-thousanders Of British Columbia
Three-thousanders are mountains with a height of between , but less than above sea level. Similar terms are commonly used for mountains of other height brackets e. g. four-thousanders or eight-thousanders. In Britain, the term may refer to mountains above . Climatological significance In temperate latitudes three-thousanders play an important role, because even in summer they lie below the zero degree line for weeks. Thus the chains of three-thousanders always form important climatic divides and support glaciation - in the Alps the contour is roughly the general limit of the "nival step"; only a few glaciated mountains are under (the Dachstein, the easternmost glaciated mountain in the Alps, is, at , not a three-thousander). In the Mediterranean, however, the three-thousanders remain free of ice and, in the tropics, they are almost insignificant from a climatic perspective; here the snow line lies at around to , and in the dry continental areas (Trans-Himalayas, Andes) ...

Canadian Alpine Journal
The ''Canadian Alpine Journal'' is the yearly magazine of the Alpine Club of Canada. It serves as a worldwide journal of record for achievements in climbing, mountaineering, ski mountaineering, and exploration of mountains. The magazine is headquartered in Toronto, Ontario. Each issue contains feature stories about notable climbs, written by the participants, as well as short notes by climbers about new and noteworthy achievements. Some general articles about mountaineering, mountain medicine, the mountain environment, or other topics are also sometimes included. Each issue includes book reviews, memorials of deceased members, and club activities. History The journal was founded in 1907, and during the early decades some volumes covered more than one year. Since 1947 (volume 30), the journal has been published annually.

List Of Peaks On The Alberta–British Columbia Border
This is a list of peaks on the Alberta–British Columbia border, being the spine of the Continental Divide from the Canada–United States border The border between Canada and the United States is the longest international border in the world. The terrestrial boundary (including boundaries in the Great Lakes, Atlantic, and Pacific coasts) is long. The land border has two sections: Can ... to the 120th meridian, which is where the boundary departs the Continental Divide and goes due north to the 60th parallel. Peaks are listed from north to south and include the four peaks not on the Continental Divide but which are on the 120th Meridian, stretching approximately due north from Intersection Mountain, which as its name implies is located at the intersection of the Divide and the Meridian.

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 a ...

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'' i ... [...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 propose ...

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.

Walter Wilcox
Walter Dwight Wilcox (1869–1949) was an early explorer of the Canadian Rockies, especially in the Lake Louise region. Life Wilcox was educated at Phillips Academy, Andover (Class of 1889) and Yale University (1893). Walter Wilcox is known for his 1890s discovery and exploration of Paradise Valley, Desolation Valley and Prospector Valley near Lake Louise. He is accredited with the first ascents of Mount Temple (3,543m), on Aug. 17, 1894 with Samuel E. S. Allen and Lewis Frissell. Walter Wilcox made the first ascent on Mount Aberdeen (3,152m), Mount Niblock (2,976m), Mount Indefatigable (2,670m), and Cheops Mountain (2581m). In 1898, Mount Wilcox (2,884m) in the Columbia Icefield area of Jasper National Park was named in Wilcox's honour by J. Norman Collie.
