The Tusk (Alaska)
The Tusk is a mountain summit in Alaska, United States. Description The Tusk is located in the Boundary Ranges of the Coast Mountains and set on land managed by Tongass National Forest. The remote peak is east of Horn Spire and north of Juneau on the northwest margin of the Juneau Icefield. Precipitation runoff and glacial meltwater from the mountain drains west to Berners Bay and Lynn Canal via the Gilkey River. Topographic relief is significant as the summit rises 5,450 feet (1,660 m) above the Battle Glacier in . History The mountain's descriptive name was applied by members of the Juneau Icefield Research Project in 1964 and the toponym was officially adopted in 1965 by the United States Board on Geographic Names.Donald J. Orth, ''Dictionary of Alaska Place Names'', U.S. Government Printing Office, 1967, page 995. The first ascent of the summit was made on August 2, 1972, by Fred Beckey, John Rupley, Dave Beckstead, and Ray Ketcham via the upper Taku Glacier.

The Snow Towers
The Snow Towers is a glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The two peaks, 0.1 mi apart, are situated at the apex of the Taku and Herbert Glaciers near the western edge of the Juneau Icefield, north of Juneau, southwest of Snowpatch Crag, and northeast of Mount Ernest Gruening, on land managed by Tongass National Forest. The mountain was named by members of the Juneau Icefield Research Project in 1964, and was officially adopted in 1965 by the U.S. Board on Geographic Names. The first ascent was made in 1984 by Charles "Dick" Ellsworth and Bruce Tickell. Climate Based on the Köppen climate classification, The Snow Towers is located in a subpolar oceanic climate zone, with long, cold, wet winters, and cool summers. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture i ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US 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 signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Juneau, Alaska
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 ...

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 separate Alaska from Washington 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. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent. 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 Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geospatial Summary Of The High Peaks/Summits Of The Juneau Icefield
The geospatial summary of the High Peaks/Summits of the Juneau Icefield is a compilation of the basic geospatial properties (location, elevation and prominence) of the peaks/summits within the general area of the Juneau Icefield located North and East of Juneau, Alaska extending north to Skagway, Alaska. The peaks are classified by elevation: 2000 m, 2050 m, 2100 m, 2150 m, 2200 m, 2250 m, 2300 m and above 2400 m. Most (216, %) of the 272 summits compiled have not been assigned an official name by the United States Geological Survey (USGS) Geographic Names Information System (GNIS) and as such are delineated as "Un-Named" (UNP in the KML file). In addition, select minor peaks are included to report those that are contained within the GNIS database and to permit assigning a location marker (coordinate) for Nunatak identification and ridge delineation for the USGS Hydrologic Unit Code boundaries for cross referencing these areal shapes to a single coordinate.

Taku Glacier
Taku Glacier (Lingít: ''T'aaḵú Ḵwáan Sít'i'') is a tidewater glacier located in Taku Inlet in the U.S. state of Alaska, just southeast of the city of Juneau. Recognized as the deepest and thickest alpine temperate glacier known in the world, the Taku Glacier is measured at thick. It is about long, and is largely within the Tongass National Forest. The glacier was originally named Schultze Glacier in 1883 and the Foster Glacier in 1890, but ''Taku'', the name the local Tlingit natives had for the glacier, eventually stuck. It is nestled in the Coast Mountains and originates in the Juneau Icefield. It is the largest glacier in the icefield and one of the southernmost tidewater glaciers of the northern hemisphere. The glacier, which converges with the Taku River at Taku Inlet, has a history of advancing until it blocks the river, creating a lake, followed by a dramatic break of the ice dam. The most recent of these advances occurred in 1750. The glacier has advanced sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Grea ...

Gulf Of Alaska
The Gulf of Alaska (Tlingit: ''Yéil T'ooch’'') is an arm of the Pacific Ocean defined by the curve of the southern coast of Alaska, stretching from the Alaska Peninsula and Kodiak Island in the west to the Alexander Archipelago in the east, where Glacier Bay and the Inside Passage are found. The Gulf shoreline is a combination of forest, mountain and a number of tidewater glaciers. Alaska's largest glaciers, the Malaspina Glacier and Bering Glacier, spill out onto the coastal line along the Gulf of Alaska. The coast is heavily indented with Cook Inlet and Prince William Sound, the two largest connected bodies of water. It includes Yakutat Bay and Cross Sound. Lituya Bay (a fjord north of Cross Sound, and south of Mount Fairweather) is the site of the largest recorded tsunami in history. It serves as a sheltered anchorage for fishing boats. Ecology The Gulf of Alaska is considered a Class I, productive ecosystem with more than 300 grams of carbon per square meter per year ...
