Kennicott Glacier
Kennicott Glacier is a glacier in the U.S. state of Alaska. It trends southeast from Mount Blackburn to its terminus at the head of the Kennicott River in the Wrangell Mountains. It is located in Wrangell-St. Elias National Park near the small town of McCarthy, Alaska and the historic ghost town of Kennecott, Alaska. It was named in 1899 by geologist Oscar Rohn of the United States Geological Survey for Robert Kennicott, pioneer Alaska explorer and director of the scientific corps of the Western Union Telegraph Expedition in 1865. Packsaddle Island is a nunatak located within the glacier near the base of Mount Blackburn. The glacier is also the namesake of the Alaska Marine Highway vessel M/V ''Kennicott''.

Mount Blackburn
Mount Blackburn is the highest peak in the Wrangell Mountains of Alaska in the United States. It is the fifth-highest peak in the United States and the twelfth-highest peak in North America. The mountain is an old, eroded shield volcano, the second-highest volcano in the U.S. behind Mount Bona and the fifth-highest in North America. It was named in 1885 by Lt. Henry T. Allen of the U.S. Army after Joseph Clay Stiles Blackburn, a U.S. senator from Kentucky. It is located in the heart of Wrangell – St. Elias National Park, the largest national park in the country. Description The mountain's massif is covered almost entirely by icefields and glaciers and is the principal source of ice for the Kennicott Glacier, which flows southeast over to just above the town of McCarthy. The mountain also contributes a large volume of ice to the north-flowing Nabesna Glacier and the Kuskulana Glacier system. Mount Blackburn is a large, dramatic peak, with great local relief and independ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Kennicott
Robert Kennicott (November 13, 1835 – May 13, 1866) was an American naturalist and herpetologist. Chronic illness kept Kennicott out of school as a child. Instead, Kennicott spent most of his time outdoors, collecting plants and animals. His father schooled him at home and convinced naturalist Jared Potter Kirtland to take him as an understudy. Soon, Kennicott was providing specimens for the Smithsonian Institution via assistant secretary Spencer Fullerton Baird. Kennicott advocated for the study and protection of native prairie animals in an era when farmers sought to eradicate them. He teamed with Northwestern University to found a natural history museum in 1857, then founded the Chicago Academy of Sciences. While in Chicago he served as a mentor to several young naturalists, including William Healey Dall. He joined the Megatherium Club and studied specimens in Hudson Bay. The Western Union Telegraph Expedition commissioned Kennicott as a scientist for their excursion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciers Of Copper River Census Area, Alaska
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Current ...

MV Kennicott
M/V ''Kennicott'' is a mainline ferry vessel for the Alaska Marine Highway System. Constructed in 1998 by the Halter Marine Group in Gulfport, Mississippi, the ''Kennicott'' has been one of the most vital vessels to the Alaska ferry system since its inception. It is nine-deck, ocean certified vessel and is also able to serve as a command and logistics vessel in the event of disaster or oil spill. The ferry system, taking advantage of her ocean-going status, sends the vessel on a monthly trans-Gulf of Alaska ("cross-gulf") voyage beginning in Juneau and concluding in Kodiak. On this voyage, the ''Kennicott'' is able to provide service to the isolated Gulf of Alaska community of Yakutat and is the only vessel to do so. The cross-gulf voyages are very popular and quite often sold out. The ''Kennicott'' and the ''Tustumena'' are the Alaska Marine Highway's only accredited ocean-going vessels. The ''Kennicott'' also serves as a mainline relief ferry in the event other ferries are out ... [...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] |
Nunatak
A nunatak (from Inuit language, Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial i ...

Western Union
The Western Union Company is an American multinational financial services company, headquartered in Denver, Colorado. Founded in 1851 as the New York and Mississippi Valley Printing Telegraph Company in Rochester, New York, the company changed its name to the Western Union Telegraph Company in 1856 after merging with several other telegraph companies. The company dominated the American telegraphy industry from the 1860s to the 1980s, pioneering technology such as telex and developing a range of telegraph-related services (including wire money transfer) in addition to its core business of transmitting and delivering telegram messages. After experiencing financial difficulties, Western Union began to move its business away from communications in the 1980s and increasingly focused on its money transfer services. The company ceased its communications operations completely in 2006, at which time The New York Times described it as "the world's largest money-transfer business" ...
