Mount Golub
Mount Golub is a prominent mountain summit located in the Chilkat Range of the Saint Elias Mountains, in the U.S. state of Alaska. This peak is situated northwest of Juneau, and west of Lynn Canal, on land managed by Tongass National Forest. Although modest in elevation, relief is significant since Mount Golub rises above tidewater in less than two miles. The mountain's name was officially adopted in 1972 by the U.S. Board on Geographic Names to commemorate Harvey Golub (1930–1971), member of the 1968 first ascent party. Other members of the party were Richard Folta, Delbert Carnes, and Keith Hart. Hart submitted the name for consideration following the September 4, 1971, untimely death of Harvey Golub who perished in the Alaska Airlines Flight 1866 disaster. That flight, which took all 111 lives aboard, crashed in a canyon approximately seven miles south of his namesake mountain. Climate Based on the Köppen climate classification, Mount Golub has a subarctic climate wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska Marine Highway System
The Alaska Marine Highway (AMH) or the Alaska Marine Highway System (AMHS) is a ferry service operated by the U.S. state of Alaska. It has its headquarters in Ketchikan, Alaska. The Alaska Marine Highway System operates along the south-central coast of the state, the eastern Aleutian Islands and the Inside Passage of Alaska and British Columbia, Canada. Ferries serve communities in Southeast Alaska that have no road access, and the vessels can transport people, freight, and vehicles. AMHS's of routes go as far south as Bellingham, Washington, in the contiguous United States and as far west as Unalaska/Dutch Harbor, with a total of 32 terminals throughout Alaska, British Columbia, and Washington. It is part of the National Highway System and receives federal highway funding. It is also the only method of transportation of vehicles between the state and the contiguous United States, not requiring international customs and immigration. The Alaska Marine Highway System is a rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mountains Of Haines Borough, 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 ...

Nun Mountain
Nun Mountain is a mountain summit in Alaska. Description Nun Mountain is located northwest of Juneau in the Chilkat Range which is a subrange of the Saint Elias Mountains. Precipitation runoff and glacial meltwater from the mountain's slopes drains to Lynn Canal. Although modest in elevation, topographic relief is significant as the summit rises over above tidewater of Lynn Canal in four miles (6.4 km) and the northeast face rises in one mile (1.6 km). The mountain's name was published by the United States Coast and Geodetic Survey in 1924 and the toponym has been officially adopted by the 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 governm .... The mountain is so named because of a fancied resemblance to a nun.

Glacier Bay National Park And Preserve
Glacier Bay National Park and Preserve is an American national park located in Southeast Alaska west of Juneau. President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 26, 1925. Chapter 8 Subsequent to an expansion of the monument by President Jimmy Carter in 1978, the Alaska National Interest Lands Conservation Act (ANILCA) enlarged the national monument by on December 2, 1980, and created Glacier Bay National Park and Preserve. Title 2, section 202(1). The national preserve encompasses of public land to the immediate northwest of the park, protecting a portion of the Alsek River with its fish and wildlife habitats, while allowing sport hunting. Glacier Bay became part of a binational UNESCO World Heritage Site in 1979, and was inscribed as a Biosphere Reserve in 1986. The National Park Service undertook an obligation to work with Hoonah and Yakutat Tlingit Native American organizations in the management of the ...

Admiralty Island
Admiralty Island is an island in the Alexander Archipelago in Southeast Alaska, at . It is long and wide with an area of , making it the seventh-largest island in the United States and the 132nd largest island in the world. It is one of the ABC islands in Alaska. The island is nearly cut in two by the Seymour Canal; to its east is the long, narrow Glass Peninsula. Most of Admiralty Island—955,747 acres (3,868 km2)—is protected as the Admiralty Island National Monument administered by the Tongass National Forest. The Kootznoowoo Wilderness encompasses vast stands of old-growth temperate rainforest. These forests provide some of the best habitat available to species such as brown bears, bald eagles, and Sitka black-tailed deer. Angoon, a traditional Tlingit community home to 572 people, is the only settlement on the island, although an unpopulated section of the city of Juneau comprises (6.2 percent) of the island's land area near its northern end.

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] |

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 ...

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 ...
