Mount Barrille
Mount Barrille is a mountain summit located in the Alaska Range, in Denali National Park and Preserve, in the U.S. state of Alaska. It is situated 2,650 feet above the Ruth Glacier at the gateway to the Don Sheldon Amphitheater, or The Great Gorge, depending on direction of travel. Barrille is set southeast of Denali, west of The Mooses Tooth, east of The Rooster Comb, and north of Mount Dickey which is the nearest higher peak. The mountain was named by famed explorer Dr. Frederick Cook for Edward Barrill (1861–1946), a horse packer from Darby, Montana, who was his sole companion during his 1906 claim to be the first to climb Denali. The claim was later disproved, and in 1909 Barrill signed an affidavit stating that they had not reached the summit. Cook referred to his companion as ''Barrille'' in his accounts of the expedition, and Barrille remains as the official spelling used by the United States Geological Survey.

Mount Dickey
Mount Dickey is a peak on the west side of the Ruth Gorge in the Central Alaska Range of mountains, 12 miles (19 km) southeast of Denali and 4 miles (6 km) southwest of The Moose's Tooth. Despite its relatively low elevation, it is notable for its east face, which has around a vertical mile (1600 m) of sheer granite—it achieves this vertical gain in less than half a mile (800m) horizontal distance. This is one of the tallest rock walls in the world, and the face has seen many world-class climbs. Mount Dickey was first climbed on April 19, 1955, by David Fisher and the famous explorer, climber and cartographer Bradford Washburn, via the West Face, which is still the most popular route today. The route begins at a point in the Ruth Gorge southeast of the peak, ascends west under the formidable south face, then turns north and then east to ascend the south side of the gently sloping West Face. This route is relatively straightforward and short for an Alaskan climb (Ala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Couloir
A couloir (, "passage" or "corridor") is a narrow gully with a steep gradient in a mountainous terrain.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, p. 121. . Geology A couloir may be a seam, scar, or fissure, or vertical crevasse in an otherwise solid mountain mass. Though often hemmed in by sheer cliff walls, couloirs may also be less well-defined, and may often simply be a line of broken talus or scree ascending the mountainside and bordered by trees, rocks or other natural features. Couloirs are especially significant in winter months when they may be filled in with snow or ice, and become much more noticeable than in warmer months when most of the snow and ice may recede. These physical features make the use of couloirs popular for both mountaineering and extreme skiing.

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 above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fake Peak
Fake Peak is a small outcrop on a ridge beside the Ruth Glacier in Denali National Park and Preserve in Alaska, US, 19 miles southeast of the summit of Denali. It has been shown by Robert M. Bryce that the "summit photograph" produced by Frederick Cook Frederick Albert Cook (June 10, 1865 – August 5, 1940) was an American explorer, physician and ethnographer, who is most known for allegedly being the first to reach the North Pole on April 21, 1908. A competing claim was made a year l ... as evidence supporting his claim to have made the first ascent of Denali was taken on Fake Peak.Robert M. Bryce"Dr. Cook – Mt.

Mountain Peaks Of Alaska
This article comprises three sortable tables of major mountain peaks of the U.S. State of Alaska. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level. The first table below ranks the 100 highest major summits of Alaska by elevation. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The second table below ranks the 100 most prominent summits of Alaska. #The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. The third table below ranks the 50 most isolated major summits of Alaska. __TOC__ Highest major summits Of the 100 highest major summits of Alaska, only Denali exceeds elevation, four peaks exceed , 23 peaks exceed , 61 peaks exceed , and 92 peaks exceed elevation. Five of these peaks lie on the internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California. * The western slope of the Wasatch Range in Utah. Specifically the Little and Big Cottonwood Canyons. * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which rece ...

Tundra Climate
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (), but no month with an average temperature in excess of . If the climate occurs at high elevations, it is known as alpine climate. Despite the potential diversity of climates in the ''ET'' category involving precipitation, extreme temperatures, and relative wet and dry seasons, this category is rarely subdivided. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes. The amount of native tundra biomass depends more on the local temperature than the amount of precipitation. Tundra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. 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'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Joe Puryear
Joseph Nicholi Puryear (1973 – October 27, 2010) was an American mountain climber and photographer. Puryear was known for his first ascents on unclimbed mountains in the Himalayas with climbing partner David Gottlieb, where he climbed Kang Nachugo, Takargo and Jobo Rinjang. Puryear died while climbing Labuche Kang (7367m) in Tibet. Early life Puryear was born in 1973 to Gail and Shirley Puryear and was raised on their winery in Yakima Valley, Washington. In his youth, he took up carpentry, winemaking and farm work, and developed an interest in mountain climbing after his parents took him to Mount Adams when he was fifteen. He attended the University of Washington, where he earned a degree in mathematics. Mountaineering Beginning in 1996, Puryear worked for four seasons as a climbing ranger at Mount Rainier National Park, where he met fellow ranger Mark Westman.

Yosemite Decimal System
The Yosemite Decimal System (YDS) is a five-part Grade (climbing), grading system used for rating the difficulty of rock climbing climbing routes, routes in the United States and Canada. It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems from the 1930s, and quickly spread throughout North America. Description The class 5 portion of the class scale is primarily a rock climbing classification system, while classes 1–4 are used for hiking and scrambling. The current definition for each class is: ; Class 1:Hiking or trail running, running on a trail. ; Class 2:Simple scrambling, with the possibility of occasional use of the hands. ; Class 3: Scrambling. A rope could be carried. ; Class 4: Simple climbing, possibly with exposure (heights), exposure. A rope is often used. Falls could be fatal. Natural protection (climbing), protection can easily be found. ; Class 5: It is considered technical roped free climbing; ...
