Athabasca Glacier
The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. The glacier currently loses depth at a rate of about per year and has receded more than and lost over half of its volume in the past 125 years. Easily accessible, it is the most visited glacier in North America. The leading edge of the glacier is within easy walking distance; however, travel onto the glacier is not recommended unless properly equipped. Hidden crevasses have led to the deaths of unprepared tourists. The Columbia Icefield Glacier Discovery Centre, closed during the winter (mid-October to mid-April), stands across from the glacier. It is used as a lodge and for ticket sales for sightseeing on the glacier. There are also two restaurants and a Starbucks located in the centre. Standard buses transport tourists from the centre to the glacier edge, where they board specially designed snow coaches for transport over the steep grades, snow and ice part w ...

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] |
Glacier Terminus
A glacier terminus, toe, or snout, is the end of a glacier at any given point in time. Although glaciers seem motionless to the observer, in reality glaciers are in endless motion and the glacier terminus is always either advancing or retreating. The location of the terminus is often directly related to glacier mass balance, which is based on the amount of snowfall which occurs in the accumulation zone of a glacier, as compared to the amount that is melted in the ablation zone. The position of a glacier terminus is also impacted by localized or regional temperature change over time. Tracking Tracking the change in location of a glacier terminus is a method of monitoring a glacier's movement. The end of the glacier terminus is measured from a fixed position in neighboring bedrock periodically over time. The difference in location of a glacier terminus as measured from this fixed position at different time intervals provides a record of the glacier's change. A similar way of trac ...

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).

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

Crevasse
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by |
Starbucks
Starbucks Corporation is an American multinational chain of coffeehouses and roastery reserves headquartered in Seattle, Washington. It is the world's largest coffeehouse chain. As of November 2021, the company had 33,833 stores in 80 countries, 15,444 of which were located in the United States. Out of Starbucks' U.S.-based stores, over 8,900 are company-operated, while the remainder are licensed. The rise of the second wave of coffee culture is generally attributed to Starbucks, which introduced a wider variety of coffee experiences. Starbucks serves hot and cold drinks, whole-bean coffee, micro-ground instant coffee, espresso, caffe latte, full and loose-leaf teas, juices, Frappuccino beverages, pastries, and snacks. Some offerings are seasonal, or specific to the locality of the store. Depending on the country, most locations provide free Wi-Fi internet access. Company overview Starbucks was founded in 1971 by Jerry Baldwin, Zev Siegl, and Gordon Bowker at Seattle's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Coach
A snow coach is a specialized passenger transport vehicle designed to operate over snow or ice, similar to a large, multi-passenger snowcat that is equipped with bus-style seating. These vehicles may have multiple sets of very large, low-pressure tires, or they may have tracks. Snow coaches may seat ten or more passengers and are often used for sightseeing tours or for over-snow transportation. History An early example of a snow coach was the Snow Bus built by Bombardier in Quebec, Canada. It was equipped with front skis and rear tracks and typically could seat 12 passengers. Alternatively, the front skis could be removed and replaced with front wheels. There are documented uses of the Bombardier Snow Bus being used as a school bus, for mail delivery, and as emergency vehicles. They were also used for tours and transportation in snowbound areas. In the early 1960s, Thiokol produced the 601 series snowcats which were often configured to carry ten passengers. While not a tour bus ...

Shock Trauma Air Rescue Service
The Shock Trauma Air Rescue Service (STARS, formerly Shock Trauma Air Rescue Society) is a Canadian non-profit helicopter air ambulance organization funded by individual donors, service groups, corporate donors and government contributions. STARS provides rapid and specialized emergency care and transportation for critically ill and injured patients. STARS operates from bases in Calgary, Edmonton, Grande Prairie, Regina, Saskatoon, Winnipeg and formerly Halifax. History STARS was formed in Calgary, Alberta to provide emergency medical care and transport to the critically ill and injured after founder Dr. Gregory Powell, who was working as an emergency room physician at the time, lost a patient: a young mother who died en route to the hospital because of the time it took to transport her by ground from her rural home. Powell had worked as a physician on Mobile Army Surgical Hospital (MASH) units during the Vietnam War and knew that a helicopter ambulance service could mean th ...
