Three Brothers Hill
Three Brothers Hill () is a conspicuous hill, 210 m, which is the remnant neck of an extinct volcano situated at the east side of Potter Cove, King George Island, in the South Shetland Islands The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1 .... The name was used by Scottish geologist David Ferguson in a 1921 report based upon his investigations of King George Island in 1913–14, but may reflect an earlier naming by whalers. The name may be suggestive of the appearance of the feature which consists of two higher summits and one which is lower.

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Potter Cove
Potter Cove is a cove indenting the south-west side of King George Island to the east of Barton Peninsula, in the South Shetland Islands of Antarctica. An extinct volcano named Three Brothers Hill is located on its east side. Potter Cove was known to sealers as early as 1821, and the name is now well established in international usage. Historic site The cove is the location of a replica of a metal plaque erected by German whaler and explorer Eduard Dallmann to commemorate the visit of his expedition, on 1 March 1874, with the sailing steamer ''Grönland''. It has been designated a Historic Site or Monument (HSM 36), following a proposal by Argentina and the United Kingdom to the Antarctic Treaty Consultative Meeting.

King George Island (Antarctica)
King George Island (Argentinian Spanish: Isla 25 de Mayo, Chilean Spanish: Isla Rey Jorge, Russian: Ватерло́о Vaterloo) is the largest of the South Shetland Islands, lying off the coast of Antarctica in the Southern Ocean. The island was named after King George III. Geography King George island has three major bays, Maxwell Bay, Admiralty Bay, and King George Bay. Admiralty Bay contains three fjords, and is protected as an Antarctic Specially Managed Area under the Protocol on Environmental Protection to the Antarctic Treaty. History The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines ''Isla Veinticinco de Mayo'' (25 May) in ho ...

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Ferguson (geologist)
David Ferguson (c. 1857 – 1936) was a Scottish explorer, mining engineer and prospector. An alumnus of the University of Glasgow, he is most known for explorations in Antarctica on private geological survey expeditions for the Scottish company, Christian Salvesen between 1911 and 1915. His notebooks indicate voyages to South Georgia Island and the South Shetland Islands between 1912 and 1915; the Falkland Islands, Zambesi and Bulawayo between 1901 and 1903; Iran Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmeni ... (1891); Newfoundland (1894); and mining surveys in Scotland. He is credited with naming several geographic locations in the south Atlantic region and Antarctica, and Ferguson Peak on South Georgia was named in his honour.

Landforms Of King George Island (South Shetland Islands)
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
