Pease Peak
Pease Peak 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 1,500 feet above the Tokositna Glacier to its west, and Ruth Glacier to the east, along the southern margin of the Don Sheldon Amphitheater, southeast of Denali, southeast of The Rooster Comb, and west of Mount Dickey, which is the nearest higher peak. Dickey forms the eastern buttress of Pittock Pass, whereas Pease forms the western buttress. Although overlooked as a climbing destination, the peak is often seen due to its proximity to the air taxi landing area and the Sheldon Chalet immediately north of the peak. Pease Peak, and its variant name Mount Pease, is based on a mountain climber's name that was published in the late 1940s.Dictionary of Alaska Place Names, Donald J. Orth author, United States Government Printing Office (1967), page 745 Climate Based on the Köppen climate classification, Pease Peak is located in an alpine c ...

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 (Alaska ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Climate
Alpine climate is the typical weather (climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mount Huntington (Alaska)
Mount Huntington is a striking rock and ice pyramid in the central Alaska Range, about 8 miles (13 km) south-southeast of Denali. It is also about 6 miles (10 km) east of Mount Hunter, and two miles west of The Rooster Comb. While overshadowed in absolute elevation by Denali, Huntington is a steeper peak: in almost every direction, faces drop over in about a mile (1.6 km). Even its easiest route presents significantly more technical challenge than the standard route on Denali, and it is a favorite peak for high-standard technical climbers. Mount Huntington was first climbed in 1964 by a French expedition led by famed alpinist Lionel Terray, via the Northwest Ridge, from then on also called the French Ridge. The second ascent the following year, via the West Face/West Rib, is reported by David Roberts in ''The Mountain of My Fear''. The mountain can be accessed either from the West Fork of the Ruth Glacier, on the north side of the mountain, or the Tokositna Glaci ...

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 its 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 Mount McKinley. 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.

Geology Of Alaska
The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean. Alaska was largely ice free during the Pleistocene, allowing humans to migrate into the Americas. Geologic History, Stratigraphy & Tectonics Compared with other areas of the North American continent, Alaska formed in the recent geologic past. Until 200 million years ago, western North America terminated at the Rocky Mountains, 120 miles further inland than the current shoreline, until the addition of the Yukon-Tanana Terrane. The Birch Creek Schist is the oldest rock in Alaska's interior and forms the core of the Yukon-Tanana Terrane with muscovite-quartz schist, mica quartzite and graphite schist. This intensely folded and rock unit extends f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
