Mount Gannett
Mount Gannett is a peak in the Chugach Mountains of eastern Alaska, United States, located east of the city of Anchorage. It was named by Lawrence Martin of the U.S. Geological Survey in 1911 for Henry Gannett. One arm of the Knik Glacier flows from the ice fields of Mount Gannett's north and east slopes, and the Colony Glacier rises on the west and southwest slopes, flowing into Inner Lake George. In between, the Gannett Glacier flows down a narrow valley northwest of the summit to join the Knik Glacier. The mountain has an estimated topographic prominence of . 1952 military transport plane crash On November 22, 1952, a United States Air Force The United States Air Force (USAF) is the Aerial warfare, air military branch, service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States.

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, Portage G ...

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Henry Gannett
Henry Gannett (August 24, 1846 – November 5, 1914) was an American geographer who is described as the "father of mapmaking in America."Evans, Richard Tranter; Frye, Helen M. (2009).History of the Topographic Branch (Division) (PDF). ''U.S. Geological Survey Circular''. 1341. . He was the chief geographer for the United States Geological Survey essentially from its founding until 1902. He was also a founding member and president of the National Geographic Society. Background Gannett was born in Bath, Maine, son of Hannah Trufant (nee Church) and Michael Farley Gannett. He attended local schools, before going to Harvard for college. He graduated with a B.S. from the Lawrence Scientific School of Harvard University in 1869 and received an M.E. at the Hooper Mining School (aka the Harvard University School of Mining and Practical Geology) in 1870. From 1870 to 1871, he was an assistant at the Harvard College Observatory. In 1871, he participated in a Harvard expedition to Spain t ...

Knik Glacier
The Knik Glacier ( Dena'ina: ''Skitnu Łi'a'') is an ice field located east of Anchorage, Alaska on the northern end of the Chugach Mountains. The ice field averages over long and over across, making it one of the largest glaciers in southcentral Alaska. Knik Glacier feeds the long Knik River which empties into the Knik Arm section of Cook Inlet. Lake George Lake George , a glacial lake formed near the face of the glacier, received national recognition by the National Natural Landmark (NNL) Program. Lake George was recognized because of a unique natural phenomenon called a "jökulhlaup", an Icelandic term for glacial lake outburst flood. The breakup of this ice dam would send a violent wall of water, ice and debris down the river valley causing massive flooding and sometimes devastation to local settlers' properties. The jökulhlaup occurred annually until it ceased in 1967 due to glacial recession, thought to be associated with the massive Good Friday earthquake of 196 ...

Colony Glacier
In modern parlance, a colony is a territory subject to a form of foreign rule. Though dominated by the foreign colonizers, colonies remain separate from the administration of the original country of the colonizers, the '' metropolitan state'' (or "mother country"). This administrative colonial separation makes colonies neither incorporated territories nor client states. Some colonies have been organized either as dependent territories that are not sufficiently self-governed, or as self-governed colonies controlled by colonial settlers. The term colony originates from the ancient Roman '' colonia'', a type of Roman settlement. Derived from ''colon-us'' (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'. Furthermore the term was used to refer to the older Greek ''apoikia'' (), which were overseas settlements by ancient Greek city-states. The city that founded such a settlement became known as its ''metropolis'' ("mother-ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gannett Glacier (Alaska)
Gannett Glacier is the largest glacier in the Rocky Mountains within the United States. The glacier is located on the east and north slopes of Gannett Peak, the highest mountain in Wyoming, on the east side of the Continental Divide in the Wind River Range. Gannett is but one of dozens of glaciers located in the Fitzpatrick Wilderness of Shoshone National Forest. As is true with many glaciers around the world, Gannett Glacier is slowly disappearing. Photographic evidence clearly demonstrates that there has been an enormous reduction in the area of the glacier since the 1920s. The area of the glacier was estimated in 1950 to be and was measured in 1999 to be . Measurements taken in 1958 and again in 1983 showed a depth reduction of over 25 years. A general warming pattern and a reduction in moisture is widely believed to be the reason for the glacier retreating. Numerous other glaciers are located in the immediate area including six more that are within the top ten in size with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...
