Boulder Cones
The Boulder Cones () are volcanic cones southwest of Castle Rock on Hut Point Peninsula, Ross Island, Antarctica. The name, which is descriptive, was given by Frank Debenham of the British Antarctic Expedition, 1910–13, who made a plane table A plane table (plain table prior to 1830) is a device used in surveying site mapping, exploration mapping, coastal navigation mapping, and related disciplines to provide a solid and level surface on which to make field drawings, charts and maps. ... survey of the peninsula in 1912.

Volcanic Cone
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Rock (Antarctica)
Castle Rock () is a bold rock crag, high, standing northeast of Hut Point on the central ridge of Hut Point Peninsula, Ross Island. It was discovered by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, who so named it because of its shape. Today, there is a recreation trail from McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the Unit ... and Scott Base which provides access to Castle Rock year round. Castle Rock Hut Castle Rock Hut () is a shelter located on a recreational trail, starting from McMurdo to Castle Rock, in order to provide a refuge in the event of a weather emergency.

Hut Point Peninsula
Hut Point Peninsula () is a long, narrow peninsula from wide and long, projecting south-west from the slopes of Mount Erebus on Ross Island, Antarctica. McMurdo Station (US) and Scott Base (NZ) are Antarctic research stations located on the Hut Point Peninsula. History The British National Antarctic Expedition (1901–04) under Robert Falcon Scott built its hut on Hut Point, a small point lying north-east of Cape Armitage, the southern headland of the peninsula. Members of the British Antarctic Expedition, 1910–13 (BAE), under Scott, wintering on Cape Evans and often using the hut during their journeys, came to refer to the whole peninsula as the Hut Point Peninsula.

Ross Island
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand. History Discovery Sir James Ross discovered it in 1840, and it was later named in honour of him by Robert F. Scott. Ross Island was the base for many of the early expeditions to Antarctica. It is the southernmost island reachable by sea. Huts built by Scott's and Shackleton's expeditions are still standing on the island, preserved as historical sites. Today Ross Island is home to New Zealand's Scott Base, and the largest Antarctic settlement, the U.S. Antarctic Program's McMurdo Station. Greenpeace established World Park Base on the island and ran it for five years, from 1987 to 1992. Geography Because of the persistent presence of the ice sheet, the island is sometimes taken to be part of the Antarctic mainland. Its are ...

Frank Debenham
Frank Debenham, OBE (26 December 1883 – 23 November 1965) was Emeritus Professor of Geography at the Department of Geography, Cambridge University and first director of the Scott Polar Research Institute. Biography Debenham was born in Bowral, New South Wales, Australia in December 1883, the younger twin and third child of Rev. John Willmott Debenham and Edith (née Cleveland). He attended the school run by his father before attending The King's School, Parramatta where he was the top academic and sporting student of his year. He graduated from the University of Sydney with a BA in English and philosophy, then joined the staff at the Anglican Armidale School in New South Wales. He returned to university in 1908, studying geology under Sir Edgeworth David. In 1910 he was one of a group of three geologists on Robert Falcon Scott's Antarctic Terra Nova Expedition (1910–1913). From January to March 1911 Debenham, along with three other expedition members (Thomas Griffith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic Expedition, 1910–13
The ''Terra Nova'' Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. Led by Captain Robert Falcon Scott, the expedition had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the ''Discovery'' Expedition from 1901 to 1904, and wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that a Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's party of five died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later. The expedition, named after its supply ship, was a private venture financed by public contributions and a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plane Table
A plane table (plain table prior to 1830) is a device used in surveying site mapping, exploration mapping, coastal navigation mapping, and related disciplines to provide a solid and level surface on which to make field drawings, charts and maps. The early use of the name ''plain table'' reflected its simplicity and plainness rather than its flatness. History The earliest mention of a plane table dates to 1551 in Abel Foullon's ''"Usage et description de l'holomètre"'', published in Paris.Turner, Anthony, ''Early Scientific Instruments, Europe 1400-1800'', Sotheby's Publishing, 1987, . page 81 However, since Foullon's description was of a complete, fully developed instrument, it must have been invented earlier. A brief description was also added to the 1591 edition of Digge's ''Pantometria''. The first mention of the device in English was by Cyprian Lucar in 1590.Turner, Gerard L'E., ''Scientific Instruments 1500-1900, An Introduction'', University of California Press, 1998 . ...
