Mount Erebus (Canada)
Mount Erebus is a mountain summit located near one of the most beautiful mountain meccas in the world, the Tonquin Valley of Jasper National Park in Alberta, Canada. Mount Erebus is composed of sedimentary rock laid down during the Cambrian period, then was pushed east and over the top of younger rock during the Laramide orogeny. Its nearest higher peak is Mount Fraser, to the northwest. The Continental Divide lies to the west, Angle Peak is situated to the southeast, and The Ramparts are to the north. The mountain's north ridge terminates at Outpost Peak. __NOTOC__ History The mountain's name was applied in 1916 by Morrison P. Bridgland (1878–1948), a Dominion Land Surveyor who named many peaks in Jasper Park and the Canadian Rockies. Bridgland was impressed with the dark colored cliffs of the northeast face of the mountain. The Greek word for ''darkness'' is ''erebus''. Bridgland would have also known about and Franklin's lost expedition. The mountain is located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outpost Peak
Outpost Peak is a double peak mountain located in the Tonquin Valley of Jasper National Park in Alberta, Canada. The northeast peak is identified on some maps as Outpost Peak, but the southwest peak is higher. Outpost Peak is composed of sedimentary rock laid down during the Cambrian period, then was pushed east and over the top of younger rock during the Laramide orogeny. Its nearest higher peak is Mount Erebus, to the south. The Continental Divide lies to the west, Angle Peak is situated to the southeast, and The Ramparts are to the north. The mountain's descriptive name was applied in 1921 by the Interprovincial Boundary Survey in keeping with the castle theme of the Ramparts area. The mountain's name was officially adopted in 1935 when approved by the Geographical Names Board of Canada. __NOTOC__ Climate Based on the Köppen climate classification, Outpost Peak is located in a subarctic climate zone with cold, snowy winters, and mild summers.

Angle Peak (Alberta)
Angle Peak is a mountain summit located in Jasper National Park, in the Canadian Rockies of Alberta, Canada. Angle Peak was named for the fact it stands where the ridge makes a bend. The descriptive name was applied in 1916 by Morrison P. Bridgland (1878-1948), a Dominion Land Surveyor who named many peaks in Jasper Park and the Canadian Rockies. The mountain's name was made official in 1935 by the Geographical Names Board of Canada. The mountain is situated in the Tonquin Valley, with Angle Glacier on its north slope, Alcove Mountain to its immediate west, The Ramparts to the northwest, and Mount Edith Cavell to the northeast. __NOTOC__ Climate Based on the Köppen climate classification, Angle Peak is located in a subarctic climate with cold, snowy winters, and mild summers.

Mountains Of Jasper 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 300 metres (1,000 feet) 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 ...

Athabasca River
The Athabasca River (French: ''Rivière Athabasca'') is a river in Alberta, Canada, which originates at the Columbia Icefield in Jasper National Park and flows more than before emptying into Lake Athabasca. Much of the land along its banks is protected in national and provincial parks, and the river is designated a Canadian Heritage River for its historical and cultural importance. The scenic Athabasca Falls is located about upstream from Jasper. Etymology The name ''Athabasca'' comes from the Woods Cree word , which means " herethere are plants one after another", likely a reference to the spotty vegetation along the river. Course The Athabasca River originates in Jasper National Park, in an unnamed lake at the toe of the Columbia Glacier within the Columbia Icefield, between Mount Columbia, Snow Dome, and the Winston Churchill Range, at an elevation of approximately . It travels before draining into the Peace-Athabasca Delta near Lake Athabasca south of Fort Chip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whirlpool River
The Whirlpool River is a short river in Jasper National Park, Alberta, Canada. It is an early tributary of the Athabasca River. The Whirlpool is formed in Athabasca Pass, collecting meltwater from the Hooker Icefield and the Mount Brown Icefield. It flows north, collecting the Middle Whirlpool River before passing under Alberta Highway 93A and flowing into the Athabasca River south of Jasper. The Moab Lake Road parallels the Whirlpool near its confluence with the Athabasca River. The Whirlpool was named by Sir James Hector in 1859. He noted the presence of many eddies in the river.Karamitsanis, Aphrodite (1991). ''Place Names of Alberta, Volume 1''.

Astoria River
The Astoria River is a short river in Jasper National Park, Alberta, Canada. It is an early tributary of the Athabasca River. The Astoria forms in the Tonquin Valley, collecting meltwater from the Fraser Glacier, The Ramparts, Mount Erebus, Mount Clitheroe, and Oldhorn Mountain. The Astoria River, as well as nearby Astoria Pass, are named after John Jacob Astor. Fur traders of the American Fur Company, owned by Astor, traveled east over Athabasca Pass from Fort Astoria, at the mouth of the Columbia River The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America.

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

First Ascent
In mountaineering, a first ascent (abbreviated to FA in guide books) is the first successful, documented attainment of the top of a mountain or the first to follow a particular climbing route. First mountain ascents are notable because they entail genuine exploration, with greater risks, challenges and recognition than climbing a route pioneered by others. The person who performs the first ascent is called the first ascensionist. In free climbing, a first ascent (or first free ascent, abbreviated FFA) of a climbing route is the first successful, documented climb of a route without using equipment such as anchors or ropes for aiding progression or resting. History The details of the first ascents of even many prominent mountains are scanty or unknown; sometimes the only evidence of prior summiting is a cairn, artifacts, or inscriptions at the top. Today, first ascents are generally carefully recorded and usually mentioned in guidebooks. The term is also used when referrin ...

Franklin's Lost Expedition
Franklin's lost expedition was a failed British voyage of Arctic exploration led by Captain (Royal Navy), Captain Sir John Franklin that departed England in 1845 aboard two ships, and , and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better understanding could aid navigation. The expedition met with disaster after both ships and their crews, a total of 129 officers and men, became icebound in Victoria Strait near King William Island in what is today the Canadian territory of Nunavut. After being icebound for more than a year ''Erebus'' and ''Terror'' were abandoned in April 1848, by which point Franklin and nearly two dozen others had died. The survivors, now led by Franklin's second-in-command, Francis Crozier, and ''Erebus''s captain, James Fitzjames, set out for the Canadian mainland and disappeared, presumably having perished.
