Tyndall Glacier (Alaska)
Tyndall Glacier is a valley/tidewater glacier in the U.S. state of Alaska. The glacier lies immediately west of 141° West longitude, within the boundaries of the Wrangell–Saint Elias Wilderness, itself part of Wrangell–St. Elias National Park & Preserve, in the borough of Yakutat, Alaska. Named for John Tyndall (a 19th-century Irish physicist, natural philosopher, and glaciologist), Tyndall Glacier originates in the basin formed by the southwestern face of Mount Saint Elias (the second-tallest mountain in the United States and the fourth-tallest in North America), as well as Mount Huxley, The Hump, and Haydon Peak in the Saint Elias Mountains. From there it extends 19 kilometers, trending southwest and terminating in Taan Fjord, an arm of Icy Bay. Together with the Yahtse and Guyot glaciers, it once occupied the entirety of Icy Bay; as the glaciers have retreated the bay has opened up. Tyndall Glacier is sometimes used as a landing area for bush planes by pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icy Bay (Alaska)
Icy Bay (Tlingit language, Tlingit: ''Lig̲aasi Áa'') is a body of water in the borough of Yakutat, Alaska, Yakutat, Alaska, formed in the last 100 years by the rapid retreat of the Guyot Glacier, Guyot, Yahtse Glacier, Yahtse, and Tyndall Glacier (Alaska), Tyndall Glaciers. It is part of the Wrangell-Saint Elias Wilderness. At the beginning of the 20th century, the bay entrance was permanently blocked by a giant tidewater glacier face that Ice calving, calved icebergs directly into the Gulf of Alaska. A century-long retreat of glaciers since 1850, glacial retreat has opened a multi-armed bay more than long. Icy Bay is a popular destination for sea kayakers, and is reachable by bush plane from Yakutat, Alaska, Yakutat, Alaska. 2015 landslide and megatsunami At 8:19 p.m. Alaska Time, Alaska Daylight Time on 17 October 2015, the side of a mountain collapsed on the western end of the head of Taan Fiord, a finger of Icy Bay formed by the retreat of Tyndall Glacier.

Natural Philosophy
Natural philosophy or philosophy of nature (from Latin ''philosophia naturalis'') is the philosophical study of physics Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which r ..., that is, nature and the physical universe. It was dominant before the development of modern science. From the ancient world (at least since Aristotle) until the 19th century, ''natural philosophy'' was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what we now call physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Vancouver
Captain George Vancouver (22 June 1757 – 10 May 1798) was a British Royal Navy officer best known for his 1791–1795 expedition, which explored and charted North America's northwestern Pacific Coast regions, including the coasts of what are now the Canadian province of British Columbia as well as the US states of Alaska, Washington and Oregon. He also explored the Hawaiian Islands and the southwest coast of Australia. Vancouver Island, the city of Vancouver in British Columbia, Vancouver, Washington in the United States, Mount Vancouver on the Canadian–US border between Yukon and Alaska, and New Zealand's fourth-highest mountain, also Mount Vancouver, are all named after him. Early life George Vancouver was born in the seaport town of King's Lynn (Norfolk, England) on 22 June 1757 - the sixth and youngest child of John Jasper Vancouver, a Dutch-born deputy collector of customs, and Bridget Berners. He came from an old respected family. The surname Vancouver comes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Ice Age
The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. It was not a true ice age of global extent. The term was introduced into scientific literature by François E. Matthes in 1939. Matthes described glaciers in the Sierra Nevada of California that he believed could not have survived the hypsithermal; his usage of "Little Ice Age" has been superseded by "Neoglaciation". The period has been conventionally defined as extending from the 16th to the 19th centuries, (noted in Grove 2004:4). but some experts prefer an alternative timespan from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals. One began about 1650, another about 1770, and the last in 1850, all of which were separated by intervals of slight warming. The Intergovernmental Panel on Climate Change Third Assessment Report considered that the timing and the areas affected by the Little Ice Age suggested largely independent ...

Bush Plane
A bush airplane is a general aviation aircraft used to provide both scheduled and unscheduled passenger and flight services to remote, undeveloped areas, such as the Canadian north or bush, Alaskan tundra, the African bush, or savanna, Amazon rainforest or the Australian Outback. They are used where ground transportation infrastructure is inadequate or does not exist. Common traits Since a bush plane is defined by how it is used, a wide variety of different aircraft with different configurations have been used over the years as such. However, experience has shown certain traits to be desirable, and so they appear frequently, especially on aircraft specifically designed as bush planes. None of these traits are mandatory - merely they are commonly seen features of bush planes. * The undercarriage is designed to be fitted with floats, skis or wheel/skis to permit operation from water or snow—primarily for Canadian, Alaskan and Russian use. * High wings ease loading and unloadi ...

Saint Elias Mountains
The Saint Elias Mountains (french: Chaîne Saint-Élie) are a subgroup of the Pacific Coast Ranges, located in southeastern Alaska in the United States, Southwestern Yukon and the very far northwestern part of British Columbia in Canada. The range spans Wrangell-St. Elias National Park and Preserve in the United States and Kluane National Park and Reserve in Canada and includes all of Glacier Bay National Park in Alaska. In Alaska, the range includes parts of the city/borough of Yakutat and the Hoonah-Angoon and Valdez-Cordova census areas. This mountain range is named after Mount Saint Elias, which in turn was named in 1741 by the Danish explorer Vitus Bering. Geology The St. Elias Mountains form the highest coastal mountain range on Earth. It formed due to the subduction of the Yakutat microplate underneath the North American Plate. The Yakutat microplate is a wedge shaped oceanic plateau with a thickness of . Similar to the adjacent Pacific plate, which has a crustal thick ...

The Hump (Alaska)
The Hump（Chinese：駝峰航線）was the name given by Allied pilots in the Second World War to the eastern end of the Himalayan Mountains over which they flew military transport aircraft from India to China to resupply the Chinese war effort of Chiang Kai-shek and the units of the United States Army Air Forces (USAAF) based in China. Creating an airlift presented the USAAF a considerable challenge in 1942: it had no units trained or equipped for moving cargo, and no airfields existed in the China Burma India Theater (CBI) for basing the large number of transports that would be needed. Flying over the Himalayas was extremely dangerous and made more difficult by a lack of reliable charts, an absence of radio navigation aids, and a dearth of information about the weather. The task was initially given to the USAAF's Tenth Air Force, and then to its Air Transport Command (ATC). Because the USAAF had no previous airlift experience as a basis for planning, it assigned comman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
