The Rooster Comb
The Rooster Comb is a multi-peak mountain located in the Alaska Range, in Denali National Park and Preserve, in the U.S. state of Alaska. It is situated 4,000 feet above the Ruth Glacier along the southwest margin of the Don Sheldon Amphitheater, southeast of Denali, east of Mount Huntington, and southeast of Mount Kudlich. The mountain's descriptive name was submitted by Bradford Washburn in 1957 based on an original description by Claude Ewing Rusk during his 1910 Mazama Expedition: ''"To our west was a remarkable mountain, rising abruptly from the snowfields to a height of at least 10,000 feet, its tip a succession of corniced spires, like a great rooster comb."'' Climate Based on the Köppen climate classification, this mountain is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The months May through June offer the most favorable weather for climbing or ...

Alaska Range
The Alaska Range is a relatively narrow, 600-mile-long (950 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest endSources differ as to the exact delineation of the Alaska Range. ThBoard on Geographic Namesentry is inconsistent; part of it designates Iliamna Lake as the southwestern end, and part of the entry has the range ending at the Telaquana and Neacola Rivers. Other sources identify Lake Clark, in between those two, as the endpoint. This also means that the status of the Neacola Mountains is unclear: it is usually identified as the northernmost subrange of the Aleutian Range, but it could also be considered the southernmost part of the Alaska Range. to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera.

Claude Ewing Rusk
Claude Ewing Rusk (November 20, 1871 – February 3, 1931), also known as C. E. Rusk, was an American mountaineer, lawyer, and author from Washington who pioneered routes up Mount Adams, Mount Baker, and Glacier Peak. He also ascended many other peaks in Washington, Oregon, and California. Personal life Early life Rusk was born on November 20, 1871, in Knox County, Illinois to James A. and Josie A. Rusk. His family emigrated from Illinois to Washington Territory in the fall of 1874. They settled in eastern Klickitat County in an area known as Wood Gulch. In 1878, Rusk's only sibling, Leah, was born. Several years later, in 1879, they moved to the foot of the Columbia Hills in the lower Klickitat Valley near Warwick. Over the next year, Rusk's father built the Happy Home stage station. Rusk often went to the top of the Columbia Hills to gaze at the various peaks of the Cascade Range. They lived in this place until Rusk was 15. They then moved to a homestead on the banks of the ...

Mountains Of Denali National Park And Preserve
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 ...

Geography Of Alaska
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About of Canadian territory separate Alaska from Washington state. Alaska is thus an exclave of the United States that is part of the Contiguous United States#Contiguous_United_States#Continental and Mainland United States, continental U.S. and the West Coast of the United States, U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via Water transport, ship or aviation, air, because no roads connect Juneau City and Borough, Alaska, Juneau to the rest of the continent. The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, Russia (Chukotka Autonomo ...

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 ...

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'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Cornice
A snow cornice or simply cornice (from the Italian cornice meaning "ledge") is an overhanging edge of snow on a ridge or the crest of a mountain and along the sides of gullies. Formation A snow cornice forms by wind blowing snow over sharp terrain breaks (e.g. the crest of the mountain) where it attaches and builds out horizontally. This build-up is most common on the steeper and leeward sides of mountains. Cornices are extremely dangerous and travelling above or below them should be avoided. When a cornice ''collapses'', it breaks in from the cornice to the top of the peak; even being on the snow on top of rock exposes the alpinist to hazard in this situation. The best practice in mountaineering is to stay far enough back from the edge so as not to be able to see the drop, as an approximate metric of exposure. Interview und Bilder zum Unglück In avalanche safety, cornices are a high avalanche danger as they often break and trigger larger avalanches that permeate several sno ...

Mazamas
The Mazamas () is a mountaineering organization based in Portland, Oregon, United States, founded in 1894. Promotion of mountaineering The Mazamas has been an important part of the climbing community in the Pacific Northwest of the United States since its founding. The Mazamas was the second mountaineering organization in the Pacific Northwest, following the Oregon Alpine Club. The Mountaineers of Seattle, Washington, which began in 1906 as an auxiliary of the Mazamas, is similar in its aims and activities to the Mazamas. The Mazamas offers more than 900 hikes and 350 climbs annually for more than 13,000 participants. A variety of classes and activities are offered for every skill and fitness level and are open to both members and nonmembers. The group also promotes mountaineering through education, climbing, hiking, fellowship, safety, and the protection of mountain environments. Founding On July 19, 1894, more than 350 people assembled near the hamlet of Government Camp at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradford Washburn
Henry Bradford Washburn Jr. (June 7, 1910 – January 10, 2007) was an American explorer, mountaineer, photographer, and cartographer. He established the Boston Museum of Science, served as its director from 1939–1980, and from 1985 until his death served as its Honorary Director (a lifetime appointment). Bradford married Barbara Polk in 1940, they honeymooned in Alaska making the first ascent of Mount Bertha together. Washburn is especially noted for exploits in four areas. *He was one of the leading American mountaineers in the 1920s through the 1950s, putting up first ascents and new routes on many major Alaskan peaks, often with his wife, Barbara Washburn, one of the pioneers among female mountaineers and the first woman to summit Denali (Mount McKinley). *He pioneered the use of aerial photography in the analysis of mountains and in planning mountaineering expeditions. His thousands of striking black-and-white photos, mostly of Alaskan peaks and glaciers, are known for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denali National Park And Preserve
Denali National Park and Preserve, formerly known as Mount McKinley National Park, is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass which is larger than the state of New Hampshire. On December 2, 1980, Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018. History Prehistory and protohistory Human habitation in the Denali Region extends to more than 11,000 years before the present, with documented sites just outside park boundaries dated to more than 8,000 years before the present.
