Mount Chichantna
Mount Chichantna is a mountain summit in Alaska. Description Mount Chichantna is located west of Anchorage in the Tordrillo Mountains which are a subrange of the Alaska Range. The remote glaciated peak ranks as the sixth-highest peak in the Tordrillo Mountains, and the 272nd-highest summit in Alaska. It is set north of Mount Spurr which is the nearest higher neighbor. Precipitation runoff from the peak's southwest slope drains to the Chakachatna River, whereas the other slopes drain to the Chichantna River. Topographic relief is significant as the east face rises nearly in two miles (3.2 km). The mountain is named in association with the Chichantna River which originates from a glacier partly located on this peak. "Chichantna" is a Denaʼina word meaning "from-glacier stream." The mountain's toponym was officially adopted in 1999 by the United States Board on Geographic Names. Climate Based on the Köppen climate classification, Mount Chichantna is located in a tundra c ...

Mount Spurr
Mount Spurr ( Dena'ina: ''K'idazq'eni'') is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898. The Alaska Volcano Observatory (AVO) rates Mount Spurr as Level of Concern Color Code Yellow. The mountain is known aboriginally by the Dena'ina Athabascan name ''K'idazq'eni'', literally 'that which is burning inside'. Mount Spurr, the highest volcano of the Aleutian Arc, is a large stratocone at the center of a roughly horseshoe-shaped caldera that is open to the south. The volcano lies west of Anchorage and northeast of Chakachamna Lake. The caldera was formed by a late-Pleistocene or early Holocene sector collapse and associated pyroclastic flows that destroyed an ancestral Spurr volcano. The debris avalanche traveled more than to the southeast, and the resulting deposit contains blocks as large as in diameter. Several ice-carved post-caldera do ...

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] |
Mount Nagishlamina
Mount Nagishlamina is an 11,068-foot (3,374 meter) glaciated mountain summit located in the Tordrillo Mountains of the Alaska Range, in the US state of Alaska. The mountain is situated west of Anchorage, northwest of Mount Spurr, and southeast of Mount Torbert, which is the nearest higher neighbor. It is the fifth-highest peak in the Tordrillo Mountains, a subset of the Alaska Range. The mountain takes its Denaʼina language name from the Nagishlamina River which drains the west side of the peak. Mount Nagishlamina's name was in use by local mountaineers since the 1970s, and was officially adopted in 1999 by the U.S. Board on Geographic Names. This geographic feature was likely the highest unclimbed peak in the United States at the time of its first ascent in 1989 by Dave Johnston. Climate Based on the Köppen climate classification, Mount Nagishlamina is located in a tundra climate zone with long, cold, snowy winters, and cool summers. Weather systems are forced upwards by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Rowel
The Rowel is a mountain summit in Alaska. Description The Rowel is located west of Anchorage in the Tordrillo Mountains which are a subrange of the Alaska Range. The remote glaciated peak ranks as the 10th-highest peak in the Tordrillo Mountains, and 598th-highest summit in Alaska. It is set northeast of Mount Spurr which is the nearest higher summit. Precipitation runoff from the peak's north slope drains to the Chichantna River, whereas the south and east slopes drain to the Chakachatna River. Topographic relief is significant as the east face rises over in one mile (1.6 km). The mountain's descriptive name "rowel" refers to the sharp-toothed wheel on the end of a spur and the toponym was officially adopted in 1999 by the United States Board on Geographic Names. The name is a pun as this sharp peak is situated around the perimeter of Mt. Spurr. [...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 ...

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.

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 ...

Denaʼina Language
Denaʼina , also Tanaina, is the Athabaskan language of the region surrounding Cook Inlet. It is geographically unique in Alaska as the only Alaska Athabaskan language to include territory which borders salt water. Four dialects are usually distinguished: # Upper Inlet, spoken in Eklutna, Knik, Susitna, Tyonek # Outer Inlet, spoken in Kenai, Kustatan, Seldovia # Iliamna, spoken in Pedro Bay, Old Iliamna, Lake Iliamna area # Inland, spoken in Nondalton, Lime Village Of the total Denaʼina population of about 900 people, only 75–95 members still speak Denaʼina. James Kari has done extensive work on the language since 1972, including his edition with Alan Boraas of the collected writings of Peter Kalifornsky in 1991. Joan M. Tenenbaum also conducted extensive field research on the language in the 1970s. Ethnonym The word is composed of the , meaning 'person' and the human plural suffix .

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...
