Mount Shand
Mount Shand is a elevation glaciated summit located at the head of the Trident Glacier in the eastern Alaska Range, in Alaska, United States.''Dictionary of Alaska Place Names'', Donald J. Orth author, United States Government Printing Office (1967), page 860. It is the third-highest peak in the Hayes Range, a subset of the Alaska Range. This remote peak is situated east-southeast of Mount Hayes, and southeast of Fairbanks. Mount Moffit, the nearest higher neighbor, is set to the northeast, and 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 name in 1949 to be applied to what is now called Mount M ...

Mount Moffit
Mount Moffit is a peak in the Alaska Range in central Alaska, United States, about 10 miles (16 km) east-southeast of Mount Hayes. It is notable for its steep faces and large relief above local terrain. For example, the north face drops 7,400 feet in approximately 1.2 miles (2 km) horizontal distance. William Shand Jr., Benjamin Ferris Jr., and Sterling Hendricks made the first ascent of Mount Moffit on August 12, 1942. All three had been part of the first ascent team for Mount Hayes the year before. Unfortunately, Shand died shortly after the climb in an unrelated car accident. It was proposed that his name be attached to this peak; however the name was mistakenly attached to a slightly lower peak to the south of Mount Moffit. This mountain was named in 1950 by the U.S. Geological Survey for Fred Howard Moffit (1874–1958) who, as a geologist with the Alaskan Branch of U.S.Geological Survey, worked in Alaska from 1903 through 1943 and authored over fifty publications d ...

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] |
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. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 the ...

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] |

Tanana River
The Tanana River (Lower Tanana: Tth'eetoo', Upper Tanana: ''Tth’iitu’ Niign'') is a tributary of the Yukon River in the U.S. state of Alaska. According to linguist and anthropologist William Bright, the name is from the Koyukon (Athabaskan) ''tene no'', ''tenene'', literally "trail river". The river's headwaters are located at the confluence of the Chisana and Nabesna rivers just north of Northway in eastern Alaska. The Tanana flows in a northwest direction from near the border with the Yukon Territory, and laterally along the northern slope of the Alaska Range, roughly paralleled by the Alaska Highway. In central Alaska, it emerges into a lowland marsh region known as the Tanana Valley and passes south of the city of Fairbanks. In the marsh regions it is joined by several large tributaries, including the Nenana (near the city of Nenana) and the Kantishna. It passes the village of Manley Hot Springs and empties into the Yukon near the town of Tanana. Ice on the riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ave ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The Alaska range is one of the higher ranges in the world after the Himalayas and the Andes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McGinnis Peak (Alaska Range)
McGinnis Peak is an elevation glaciated summit located at the head of McGinnis Glacier in the eastern Alaska Range, in Alaska, United States. It is the eighth-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 Moffit, the nearest higher neighbor, is set to the northwest, and Mount Shand is positioned to the west. The Richardson Highway is to the east, with Hayes, McGinnis, and Moffit dominating the landscape along the drive south. Enormous rockslides fell from McGinnis Peak during the 2002 Denali earthquake, which had an epicenter 35 miles to the west. The slides released a significant volume of deposits. Climate Based on the Köppen climate classification, McGinnis Peak is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. This climate supports the Trident, Black Rapids, and McGinnis Glaciers surrounding this peak. Temperatures can drop bel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
