Mount Gilbert (Chugach Mountains)
Mount Gilbert is a prominent glaciated mountain summit located in the Chugach Mountains, in the U.S. state of Alaska. The peak is situated east of Anchorage, northeast of Whittier, Alaska, Whittier, and northeast of Mount Muir (Alaska), Mount Muir, on land managed by Chugach National Forest. Although modest in elevation, Topographic relief, relief is significant since the mountain rises up from tidewater at Harriman Fjord in Prince William Sound in less than six miles. History The peak was named in 1908 by Ulysses Sherman Grant and Daniel F. Higgins for Grove Karl Gilbert (1843-1918}, a geologist with the United States Geological Survey who was part of the 1899 Harriman Alaska expedition that explored this area. The mountain's name was officially adopted in 1910 by the U.S. Board on Geographic Names. On June 14, 1960, a Pacific Northern Airlines Lockheed L-749A Constellation aircraft crashed near the summit, killing all 14 persons aboard. It was on the final leg of a flight ...

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains Of 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 and ...

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] |
List Of Mountain Peaks Of Alaska
This article comprises three sortable tables of major mountain peaksThis article defines a significant summit as a summit with at least of topographic prominence, and a major summit as a susexxleast of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. 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.If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown. 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 topographic prominence of a summit is the topographic elevation difference between the ...

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] |
First Ascent
In mountaineering, a first ascent (abbreviated to FA in guide books) is the first successful, documented attainment of the top of a mountain or the first to follow a particular climbing route. First mountain ascents are notable because they entail genuine exploration, with greater risks, challenges and recognition than climbing a route pioneered by others. The person who performs the first ascent is called the first ascensionist. In free climbing, a first ascent (or first free ascent, abbreviated FFA) of a climbing route is the first successful, documented climb of a route without using equipment such as anchors or ropes for aiding progression or resting. History The details of the first ascents of even many prominent mountains are scanty or unknown; sometimes the only evidence of prior summiting is a cairn, artifacts, or inscriptions at the top. Today, first ascents are generally carefully recorded and usually mentioned in guidebooks. The term is also used when referrin ...

Cordova, Alaska
Cordova ( ) is a city in Chugach Census Area, Alaska, United States. It lies near the mouth of the Copper River, at the head of Orca Inlet on the east side of Prince William Sound. The population was 2,609 at the 2020 census, up from 2,239 in 2010. Cordova was named ''Puerto Córdoba'' (after Córdoba, Spain) by Spanish explorer Salvador Fidalgo in 1790. No roads connect Cordova to other Alaskan communities, so a plane or ferry is required to travel there. In the Exxon Valdez oil spill of March 1989, an oil tanker ran aground northwest of Cordova, heavily damaging ecology and fishing. It was cleaned up shortly after, but there are lingering effects, such as a lowered population of some birds. History In 1790 the inlet in front of the current Cordova townsite was named Puerto Cordova by Spanish explorer Salvador Fidalgo, after Spanish admiral Luis de Córdova y Córdova. The city of Cordova was named after it, although the inlet itself was later renamed the Orca Inlet. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed L-749A Constellation
The Lockheed L-749 Constellation is the first Lockheed Constellation to regularly cross the Atlantic Ocean non-stop. Although similar in appearance to the Lockheed L-649 Constellation, L-649 before it, the L-749 had a larger fuel capacity, strengthened landing gear, and eventually weather radar. Design and development In early 1947, the Lockheed Aircraft Corporation unveiled the L-749, a derivative of its L-649 Constellation with fuel tanks to increase its maximum range by . Due to the increased weight, the landing gear and tires had to be strengthened. Turbo-compound_engine#History, Jet stacks were also introduced, increasing speed by . These jet stacks increased the noise, requiring more insulation. As with the L-649, ten different layouts of the internal cabin were possible. Airlines originally attracted to the L-649 changed their orders to the L-749. The L-749 was to become the standard version of the regular Constellation.Breffort, ''Lockheed Constellation'', pp. 40-45. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
