Mount Athabasca
Mount Athabasca is 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 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.Geography of Alberta __NOTOC__ Routes There are several climbing routes, including: * North Glacier (Normal Route) II * Silverhorn II * AA Col II * Regular North Face III 5.8 * North Ridge III 5.5 * The Hourglass 300m, III, AI3-4 One of the most prominent features of Mount Athabasca is a horned-shaped tip near the top called the "Silverhorn".

Canadian Rockies
The Canadian Rockies () 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). The Canadian Rockies, being the northern segment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

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. Because of the susceptibility of ice 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 unint ...

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...

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 can be described as being between hiking and climbing, rock climbing. "A scramble" is a related term, denoting terrain that could be ascended in this way. Sure-footedness and a head for heights are essential. Canyoning and stream climbing both involve scrambling. Overview Scrambling is ascending or traversing a grade without technical apparatus. Unroped ascent in exposure (heights), 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-t ...

Blue Ice (glacial)
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. Water is blue in large quantities, 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 of the vi ...

Grade (climbing)
Many climbing routes have grades for the technical difficulty, and in some cases for the risks, of the route. The first ascent, first ascensionist can suggest a grade but it will be amended for the ''consensus view'' of subsequent ascents. While many countries with a tradition of climbing developed their own grading systems, a small number of grading systems have become internationally dominant for each type of climbing, and which has led to the standardization of grading worldwide. Over the years, grades have List of grade milestones in rock climbing, consistently risen in all forms of climbing, helped by improvements in climbing technique and climbing equipment, equipment. In free climbing (i.e. climbing rock routes with no aid), the most popular grading systems are the French numerical or sport system (e.g. f7c+), the American YDS system (e.g. 5.13a), and latterly the UIAA scale (e.g. IX+). These systems grade technical difficulty being the main focus of the lower-risk a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Athabasca
Lake Athabasca ( ; French: ''lac Athabasca''; from Woods Cree: , " herethere are plants one after another") is in the north-west corner of Saskatchewan and the north-east corner of Alberta between 58° and 60° N in Canada. The lake is about 30% in Alberta and 70% in Saskatchewan. The lake is fed by the Athabasca River and other rivers, and its water flows northward via the Slave River to the Mackenzie River system, eventually reaching the Arctic Ocean. Toponymy The name in the Woods Cree language originally referred only to the Peace–Athabasca Delta formed by the confluence of the Peace and Athabasca rivers 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 signifie ...

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 70 ...

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, in depth and receives up to of snowfall per year. Geology The Columbia Icefield sits on a large area of relatively horizontal layers of rock. Because flat-lying layers erode more slowly than the surrounding tilted areas, the surface remains higher-altitude and therefore colder. The 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.
