Jeffries Peak
Jeffries Peak () is a peak standing southward of Wilhelmina Bay, between Leonardo Glacier and Blanchard Glacier on the west coast of Graham Land, Antarctica. It was mapped by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57, and was named by the UK Antarctic Place-Names Committee for John Jeffries, an American physician who, with Jean Blanchard, made the first balloon crossing of the English Channel The English Channel, "The Sleeve"; nrf, la Maunche, "The Sleeve" (Cotentinais) or ( Jèrriais), (Guernésiais), "The Channel"; br, Mor Breizh, "Sea of Brittany"; cy, Môr Udd, "Lord's Sea"; kw, Mor Bretannek, "British Sea"; nl, Het Kana ... in 1785.

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 ...

Wilhelmina Bay
Wilhelmina Bay is a bay wide between the Reclus Peninsula and Cape Anna along the west coast of Graham Land on the Antarctic Peninsula. It was discovered by the Belgian Antarctic Expedition of 1897-99 led by Adrien de Gerlache. The bay is named for Wilhelmina, Queen of the Netherlands The monarchy of the Netherlands is a constitutional monarchy. As such, the role and position of the monarch are governed by the Constitution of the Netherlands. Consequently, a large portion of it is devoted to the monarch. Roughly a third of ..., who reigned from 1890 to 1948. Wilhelmina Bay is dubbed "Whale-mina Bay" for its large number of humpback whales. It is a popular destination for tourist expedition ships to Antarctica thanks to its abundant whale population and spectacular scenery. The bay is surrounded by steep cliffs full of snow and glaciers. An almost perfect pyramid-shaped peak towers over the water.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Hunting Aerosurveys Ltd
Hunting Aerosurveys Ltd was a British aerial photography company founded by Percy Hunting in 1944. Its operations became more diversified under the name Hunting Surveys. History The firm incorporated Aerofilms Ltd and the Aircraft Operating Company. In 1947 it was using three types of aircraft: Austers, a Percival Proctor and a de Havilland Dragon Rapide and planned to acquire one or more Percival Mergansers. The company had contracts for work surveying for tin mining in Nigeria; oil in Arabia, Venezuela and Colombia; timber in Ontario; and mapping in Australia & Hong Kong (in 1963). Between 1957 and 1964, Hunting operated a specially converted Auster Autocar for smaller scale aerial survey work. In 1960 the firm was merged with Hunting Geophysics Ltd to form Hunting Surveys Ltd. Threatened with closure in the mid-1980s, it was merged with sister company Hunting Aerofilms Ltd to become simply Aerofilms Ltd in 1987. The new company was able to provide state-of-the-art seria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.

Jean-Pierre rançoisBlanchard (4 July 1753 – 7 March 1809) was a French inventor, best known as a pioneer of gas balloon flight, who distinguished himself in the conquest of the air in a balloon, in particular the first crossing of the English Channel, on 7 January 1785. Biography 1784 - Flights in Paris Blanchard made his first successful balloon flight in Paris on 2 March 1784, in a hydrogen gas balloon launched from the Champ de Mars. The first successful manned balloon flight had taken place on 21 November 1783, when Pilâtre de Rozier and the Marquis d'Arlandes took off at Palace of Versailles in a free-flying hot air balloon constructed by the Montgolfier brothers. The first manned hydrogen balloon flight had taken place on 1 December 1783, when Professor Jacques Charles and Nicolas-Louis Robert launched '' La Charlière'' from the Jardin des Tuileries in Paris.

Mountains Of Graham 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 ...
