Murphy Peak () is a prominent, partly ice-covered peak, 1,280 m, standing at the south side of Salmon Glacier, 2.7 nautical miles (5.0 km) southwest of Haggerty Hill, on the Scott Coast, Victoria Land. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1992 after Robert L. Murphy of Holmes and Narver, Inc., manager of the support contractor to the U.S. Antarctic Program The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ..., 1976–80 and 1990–92; responsible for integrating operations of the (resulting in shared logistics and engineering capabilities) and for preparation of the McMurdo Station Long-Range Development Plan used to modernize infrastructure, 1980–92.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Salmon Glacier
The Salmon Glacier is a glacier located ~ north of Stewart, British Columbia, and Hyder, Alaska, just on the Canadian side of the border. The glacier, one of hundreds in the Boundary Ranges, is notable for its major potential as a natural hazard. Summit Lake is located at the northern end of the glacier and every year around mid-July the lake breaks an ice-dam and then flows under the Salmon Glacier into the Salmon River. This causes the river to rise approximately for several days. The glacier can be accessed by road from Hyder, Alaska, from early July to late September. The glacier's name was officially adopted January 20, 1955, by the Geographical Names Board of Canada. Climate Based on the Köppen climate classification, Salmon Glacier is located in the marine west coast climate zone of western North America. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), ...

Scott Coast
Scott Coast () is the portion of the coast of Victoria Land, Antarctica between Cape Washington and Minna Bluff. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Captain Robert Falcon Scott, Royal Navy, leader of the ''Discovery'' Expedition (1901–1904) and the British Antarctic Expedition (1910-1913), who died on the return journey from the South Pole. Much of the early exploration of this coastline was accomplished by Scott and his colleagues, and many of the names in the region were bestowed by him.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo Station Long-Range Development Plan
Vice-Admiral Archibald McMurdo (24 September 1812 – 11 December 1875) was a Scottish naval officer and polar explorer after whom Antarctica's McMurdo Sound, McMurdo Station, McMurdo Ice Shelf, McMurdo Dry Valleys and McMurdo–South Pole Highway are named. Early life Archibald William McMurdo was born on September 24, 1812 in Scotland. He was the son of Lieutenant Colonel Archibald McMurdo and grandson of John McMurdo, a chamberlain at Drumlanrig Castle. Career McMurdo joined the Royal Navy on 6 October 1824, at the age of 12. He was promoted to Lieutenant in 1836 for his skill and courage in saving the crew of a shipwrecked whaler from hostile New Zealand natives. He achieved the rank of Commander in 1843 and Captain in 1851. His career included two discovery expeditions aboard HMS ''Terror'', the first to Hudson Bay (1836-1837), the second to Antarctica (1839-1842). In 1836 he served on HMS Volage during its voyage to East India. During the Antarctica voyage, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Victoria Land
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 ...
