Mount Balchen (Alaska)
Mount Balchen is an mountain summit in Alaska, United States. Description Mount Balchen is a glaciated mountain located on the crest of the eastern Alaska Range. It is the ninth-highest peak in the Hayes Range which is a subrange of the Alaska Range. This remote peak is situated west of Mount Hayes and south-southeast of Fairbanks. Precipitation runoff from the mountain drains north into tributaries of the Tanana River and south to the Susitna River. Topographic relief is significant as the summit rises 3,700 feet (1,128 m) above the Hayes Glacier in 0.65 mile (1 km). The first ascent of the summit was made on April 30, 1974, by Dusan Jagersky and William Q. Sumner via the east ridge. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hayes
Mount Hayes is the highest mountain in the eastern Alaska Range, in the U.S. state of Alaska. Despite not being a fourteener, it is one of the largest peaks in the United States in terms of rise above local terrain. For example, the Northeast Face rises 8,000 feet (2,440 m) in approximately 2 miles (3.2 km). This large vertical relief contributes to Mount Hayes being the 51st most topographically prominent peak in the world. The mountain was named in 1898 by W. J. Peters and A. H. Brooks of the U.S. Geological Survey for Charles Willard Hayes (1858–1916), a geologist with the Survey from 1887 through 1911. Mount Hayes was first climbed on August 1, 1941, by Bradford Washburn, Barbara Washburn, Benjamin Ferris, Sterling Hendricks, Henry Hall, and William Shand. Today's standard climbing route is the East Ridge (Alaska Grade 2+). Mount Hayes is not frequently climbed due to its remoteness and the resulting access difficulties.

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Southeast Fairbanks Census Area, Alaska
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

This remote peak is situated east-southeast of Mount Hayes, and southeast of Fairbanks, Alaska, Fairbanks. Mount Moffit, the nearest higher neighbor, is set to the northeast, and McGinnis Peak (Alaska Range), McGinnis Peak is positioned to the east. This rarely climbed mountain has three large sweeping faces, the East, West, and South. This mountain is named for William Shand Jr. (1918–1946), a mountaineer who made the first ascents of nearby Mount Moffit in August 1942, and Mount Hayes on August 1, 1941. Following Shand's untimely death in a tragic car crash, Bradford Washburn, also of the Hayes first ascent party, proposed this na ...

Moby Dick (Alaska)
Moby Dick is a elevation glaciated summit located at the head of the Trident Glacier in the eastern Alaska Range, in Alaska, United States. It is the fourth-highest peak in the Hayes Range, a subset of the Alaska Range. This remote peak is situated southeast of Mount Hayes, and southeast of Fairbanks. Mount Shand, the nearest higher neighbor, is set to the east. The first ascent of this unofficially named mountain was made in 1964 by Christopher Goetze, Lydia Goetze, Tom Knott, and Larry Muir. Climate Based on the Köppen climate classification, Moby Dick is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. This climate supports the Trident, Susitna, and Black Rapids Glaciers surrounding this peak. 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 viewing. Precipitation runoff from the mountain drains into tributaries of th ...

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 ex ... [...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] |
