Mount Athabasca
Mount Athabasca is located in the Columbia Icefield of Jasper National Park in Canada. The mountain was named in 1898 by J. Norman Collie, who made the first ascent on August 18 of that year. Athabasca is the Cree language Cree (also known as Cree– Montagnais–Naskapi) is a dialect continuum of Algonquian languages spoken by approximately 117,000 people across Canada, from the Northwest Territories to Alberta to Labrador. If considered one language, it is th ... name for "where there are reeds", which originally referred to Lake Athabasca. Mount Athabasca is unusual, in that water flows to the Pacific Ocean from the western slope, the Arctic Ocean from the northeastern slope, and to Hudson Bay from the southeastern slope.

Canadian Rockies
The Canadian Rockies (french: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico. Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system).

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 ...

Icefields Parkway Near Columbia Icefield
An ice field (also spelled icefield) is a mass of interconnected valley glaciers (also called mountain glaciers or alpine glaciers) on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form. The higher peaks of the underlying mountain rock that protrude through the icefields are known as nunataks. Ice fields are larger than alpine glaciers, but smaller than ice caps and ice sheets. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes. Formation Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Due to ice's susceptibility to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted b ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Scrambling
Scrambling is a mountaineering term for ascending steep terrain using one's hands to assist in holds and balance.''New Oxford American Dictionary''. It is also used to describe terrain that falls between hiking and rock climbing (as a “scramble”). Sure-footedness and a head for heights are essential. Canyoning and stream climbing are other types of scrambling. Overview Scrambling is ascending or traversing a grade without technical apparatus. Unroped ascent in exposed situations is potentially one of the most dangerous of mountaineering activities. As soon as an ascent involves a rope, going up or down, it is no longer a scramble. Alpine scrambling Alpine scrambling is scrambling in high mountains and may not follow a defined or waymarked path. The Seattle Mountaineers climbing organization defines alpine scrambling as follows: Alpine Scrambles are off-trail trips, often on snow or rock, with a 'non-technical' summit as a destination. A non-technical summit is one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Ice (glacial)
__NOTOC__ Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of the glacier. During compression, air bubbles are squeezed out, so ice crystals enlarge. This enlargement is responsible for the ice's blue colour. Small amounts of regular ice appear to be white because of air bubbles inside and also because small quantities of water appear to be colourless. In glaciers, the pressure causes the air bubbles to be squeezed out, increasing the density of the created ice. Large quantities of water are blue, as it absorbs other colours more efficiently than blue. A large piece of compressed ice, or a glacier, similarly appears blue. The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end ...

Grade (climbing)
In rock climbing, mountaineering, and other climbing disciplines, climbers give a grade to a climbing route or boulder problem, intended to describe concisely the difficulty and danger of climbing it. Different types of climbing (such as sport climbing, bouldering or ice climbing) each have their own grading systems, and many nationalities developed their own, distinctive grading systems. There are a number of factors that contribute to the difficulty of a climb, including the technical difficulty of the moves, the strength, stamina and level of commitment required, and the difficulty of protecting the climber. Different grading systems consider these factors in different ways, so no two grading systems have an exact one-to-one correspondence. Climbing grades are inherently subjective.Reynolds Sagar, Heather, 2007, ''Climbing your best: training to maximize your performance'', Stackpole Books, UK, 9.

Lake Athabasca
Lake Athabasca (; French: ''lac Athabasca''; from Woods Cree: , "herethere are plants one after another") is located in the north-west corner of Saskatchewan and the north-east corner of Alberta between 58° and 60° N in Canada. The lake is 26% in Alberta and 74% in Saskatchewan. History The name in the Dene language originally referred only to the large delta formed by the confluence of the Athabasca River at the southwest corner of the lake. Prior to 1789, Sir Alexander Mackenzie explored the lake. In 1791, Philip Turnor, cartographer for the Hudson’s Bay Company, wrote in his journal, "low swampy ground on the South side with a few willows growing upon it, from which the Lake in general takes its name Athapison in the Southern Cree tongue which signifies open country such as lakes with willows and grass growing about them". Peter Fidler originally recorded the name for the river in 1790 as ''the Great Arabuska''. By 1801, the name had gained a closer spelling to the ...

List Of Mountains Of Alberta
Most of Alberta's mountains are found on the western edge of the province of Alberta, consisting of the eastern slopes of the Canadian Rockies, which run through the province from Alberta's mid-point to its southern border with the United States. Other elevated spots can be found in the Caribou Mountains and the Cypress Hills. The peaks of the Canadian Rockies are majestic, many of them reaching a height of more than three kilometres above sea level. Alberta's southwestern boundary is traced on the Continental Divide, along the high ranges of the Rocky Mountains, and many peaks are located on the Alberta–British Columbia border. The peak of Mount Columbia, within Jasper National Park, is the highest point in Alberta, second highest in the Canadian Rockies and 28th highest in Canada. The Caribou Mountains are located in the northern extremity of Alberta, forming an elevated plateau in the northern plains and wetlands. They reach an altitude of 1,030 m, almost 700&n ...

Cree Language
Cree (also known as Cree– Montagnais–Naskapi) is a dialect continuum of Algonquian languages spoken by approximately 117,000 people across Canada, from the Northwest Territories to Alberta to Labrador. If considered one language, it is the aboriginal language with the highest number of speakers in Canada. The only region where Cree has any official status is in the Northwest Territories, alongside eight other aboriginal languages. There, Cree is spoken mainly in Fort Smith and Hay River.

Columbia Icefield
The Columbia Icefield is the largest ice field in North America's Rocky Mountains. Located within the Canadian Rocky Mountains astride the Continental Divide along the border of British Columbia and Alberta, Canada, the ice field lies partly in the northwestern tip of Banff National Park and partly in the southern end of Jasper National Park. It is about in area, to in depth and receives up to of snowfall per year. History The Columbia Icefield was formed during the Great Glaciation, or Illinoisan period (238,000 to 126,000 BCE).Sandford 1993, p. 23. The initial advancement of the ice field ended during the latter millennia of the Early Wisconsinan period (73,000 to 62,000 BCE), around the time ''Homo sapiens'' began to appear on the earth. The next major advance of the ice field occurred during the Late Wisconsinan period (18,000 to 9,000 BCE), which marked the end of the major intercontinental land mass bridges. During the Crowfoot Glacier advance (9,000 to 7,000 BCE) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
