Mount Fellows
Mount Fellows is a mountain summit in Alaska, United States. Description Mount Fellows is located east of Denali National Park headquarters and northwest of Pyramid Mountain in the Alaska Range. Precipitation runoff from the mountain drains into tributaries of the Nenana River, which in turn is part of the Tanana River drainage basin. Although modest in elevation, topographic relief is significant as the summit rises over 2,800 feet (914 m) above the Nenana River in . The mountain's name was reported in 1950 by the USGS,Donald J. Orth, ''Dictionary of Alaska Place Names'', U.S. Government Printing Office, 1967, page 330. and the toponym has been officially adopted by the United States Board on Geographic Names. Climate Based on the Köppen climate classification, Mount Fellows is located in a subarctic climate The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, w ...

Sugar Loaf Mountain (Alaska)
Sugar Loaf Mountain, also known as Sugar Mountain, is a summit located in the Alaska Range, near Denali National Park and Preserve, in Alaska, United States. It is situated northeast of park headquarters and southeast of Healy. The George Parks Highway and Alaska Railroad traverse the western base of this mountain as each passes through the Nenana River Gorge. Mount Healy, Sugar's nearest higher neighbor, is set to the west across the gorge. This peak's local descriptive name was published in 1950 by the United States Geological Survey.''Dictionary of Alaska Place Names'', Donald J. Orth author, United States Government Printing Office (1967), page 925. Climate Based on the Köppen climate classification, Sugar Loaf Mountain is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Winter 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 v ...

Tanana River
The Tanana River (Lower Tanana language, Lower Tanana: Tth'eetoo', Upper Tanana language, 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 language, Koyukon (Athabaskan) ''tene no'', ''tenene'', literally "trail river". The river's headwaters are located at the confluence of the Chisana River, Chisana and Nabesna River, Nabesna rivers just north of Northway, Alaska, 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, Alaska, Fairbanks. In the marsh regions it is joined by several large tributaries, including the Nenana River, Nenana (near the city of Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 consisting of British Columbia (in Canada) separate Alaska from Washington U.S. state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. 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 Autonomous Okrug), Bering Sea, the Bering Strait, and the Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere, it is technically both the westernmost and easternmost state in the United States, as well as also being the northernmo ...

List Of 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] |
Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a continental 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°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. 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 on ... [...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 ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a Federal government of the United States, federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geography, geographic names throughout the federal government of the United States. History Following the American Civil War, more and more American pioneer, American settlers began moving westward, prompting the Federal government of the United States, U.S. federal government to pursue some sort of consistency for referencing landmarks on maps and in official documents. As such, on January 8, 1890, Thomas Corwin Mendenhall, superintendent of the United States Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Relief
Terrain (), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drainage characteristics, drainage systems, groundwater systems, water ...

Nenana River
The Nenana River () is a tributary of the Tanana River, approximately long, in central Alaska in the United States. It drains an area on the north slope of the Alaska Range on the south edge of the Tanana Valley southwest of Fairbanks, Alaska, Fairbanks. It issues from the Nenana Glacier in the northern Alaska Range, southwest of Mount Deborah, approximately 100 mi (160 km) south of Fairbanks. It flows briefly southwest, then west, then north, forming the eastern boundary of Denali National Park and Preserve. It emerges from the mountains onto the broad marshy Tanana Valley, joining the Tanana River from the south at Nenana, Alaska, approximately southwest of Fairbanks. The Tanana River continues to its confluence with the Yukon River. The upper valley of the river furnishes approximately 100 mi (160 km) of the northern route of both the Alaska Railroad and the George Parks Highway, Parks Highway (Alaska State Highway 3) connecting Fairbanks and Anchorage, Al ...

Alaska Range
The Alaska Range is a relatively narrow, mountain range in the Southcentral Alaska, 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 (Yukon), White River in Canada's Yukon Territory in the southeast.

Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...
