Aiguille Peak
Aiguille Peak is a peak located on the Canadian provincial boundary of Alberta and British Columbia in Banff National Park. It was named in 1915 by Arthur O. Wheeler. "Aiguille" is French for "needle" and is also a mountaineering term for a sharp-ridged summit.__NOTOC__ Geology Aiguille Peak 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 Laramide orogeny. Climate Based on the Köppen climate classification, Aiguille Peak is located in a subarctic climate The subarctic climate (also called subpolar climate, or boreal climate) is a continental 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 ... zone with cold, snowy winters, and mild summers.

Waputik Range
The Waputik Range lies west of the upper Bow Valley, east of Bath Creek, and south of Balfour Creek in the Canadian Rockies. "Waputik" means "white goat" in Stoney. The range was named in 1884 by George Mercer Dawson of the Geological Survey of Canada. The President Range lies within the Waputik Range. The Waputik Range should not be confused with the much larger Waputik Mountains which encompasses this range and other peaks along the Continental Divide in Yoho National Park Yoho National Park ( ) is a National Parks of Canada, national park of Canada.

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 ...

Mountains Of Banff National Park
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

List Of Peaks On The British Columbia–Alberta Border
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Blaeberry River
The Blaeberry River is a tributary of the Columbia River in the Columbia Country of British Columbia, Canada, rising in the Canadian Rockies on the south side of Howse Pass and joining the Columbia midway between the town of Golden, at the confluence of the Kicking Horse River, and the east foot of the Rogers Pass, at the head of Kinbasket Lake and the mouth of the Beaver River. Its length is about . Known to explorer David Thompson in 1807 as Portage Creek, in 1811 another fur company explorer, Alexander Henry the younger, named it the "Blaeberry Torrent", after the abundant berry bushes seen lining its bank (these were likely huckleberries) - "Blae" is Scots language for "blue". The river has sometimes been incorrectly labelled the Blueberry River. Blaeberry Falls is on the lower reaches of the river, approximately up from its confluence with the Columbia.

Mistaya River
The Mistaya River is a short river in western Alberta, Canada. It flows through the Canadian Rockies, and a section of the Icefields Parkway was built along its course. Mistaya River originates in Peyto Lake, a glacial lake of typical blue colour (due to rock flour). Mistaya flows north-west, receiving the waters of creeks such as Delta, Silverhorn, Cirque, Noyes, Chephren, Totem, Epaulette, Bison, Kaufmann and Sarbach. A series of elongated lakes are formed along the river: Mistaya Lake and Waterfowl Lakes. Mistaya merges into the North Saskatchewan River at Saskatchewan River Crossing. From its headwaters of Peyto Creek, Mistaya River has a total length of 38 km. The origin of the name is from the Cree language: () means 'grizzly bear'.

Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental 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°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. 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 on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. 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'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

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 ...

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.

Howse Peak
Howse Peak is the highest mountain in the Waputik Mountains, a subrange of the Canadian Rockies. It is located west of the Icefields Parkway, above Chephren Lake, on the continental divide between Alberta and British Columbia. At , it is the 46th highest peak in Alberta, and the 59th highest in British Columbia. Howse Peak's name comes from Howse Pass, which lies to the west. The pass was named by David Thompson, after the Hudson's Bay Company trader Joseph Howse, who crossed the pass in 1809. (Thompson had actually crossed the pass two years earlier.) Climbing Howse Peak is a dramatic mountain, rising over above both the Mistaya River to the east and Howse Pass to the west, in only a few horizontal kilometres.''Map of Bow Lake and Saskatchewan Crossing'', Gem Trek Publishing, 1995, It is also a formidable climbing challenge. The easiest route requires a hike up the Howse River and then a climb up a glacier on the west side of the peak. In addition, at least two high-q ...
