Ravelin Ridge
Ravelin Ridge is a ridge which extends north–south and rises to 1400 m ( Jerez Peak) in northern Clarence Island, in the South Shetland Islands of Antarctica. It is connected to Urda Ridge to the south by Soyka Saddle, and has its east slopes drained by Treskavets, Orcho and Banari Glaciers. The UK Antarctic Place-Names Committee (UK-APC) applied the name in 1971 following mapping by the Joint Services Expedition, 1970-71. The feature resembles a fortification, hence the use of the term "ravelin A ravelin is a triangular fortification or detached outwork, located in front of the innerworks of a fortress (the curtain walls and bastions). Originally called a ''demi-lune'', after the ''lunette'', the ravelin is placed outside a castle ...". References Ridges of the South Shetland Islands {{ClarenceIsland-geo-stub ...

South is one of the cardinal directions or Points of the compass, compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic language, Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European language, Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the ...

Jerez Peak
Jerez Peak ( bg, връх Херес, vrah Heres, ) is the ice-covered peak rising to 1400 m at the south extremity of Ravelin Ridge on Clarence Island in the South Shetland Islands, Antarctica. It is connected to Mount Llana by Soyka Saddle, and surmounts Treskavets Glacier to the northeast and Highton Glacier to the southeast. The peak is named after the Spanish mariner Gregorio Jerez who made the second sighting of Roché Island (South Georgia, named by him ''Isla San Pedro'') in 1756. Location Jerez Peak is located at , which is 2 km north-northeast of Mount Llana and 5 km south of Humble Point. British mapping in 1972 and 2009.

Clarence Island (South Shetland Islands)
Clarence Island (russian: остров Шишкова) is the easternmost island in the South Shetland Islands, off the coast of Antarctica. It is claimed by Argentina as part of Argentine Antarctica, by Britain as part of the British Antarctic Territory, and by Chile as part of the Chilean Antarctic Territory. The name dates back to at least 1820 and is now established in international usage, except for Russia, where it has been known as Shishkova Island since its discovery by Russians in 1821. The island is long and oriented in a south-southwest to north-northeast direction. Ravelin Ridge and Urda Ridge occupy the interior of the mountainous island. The summit Mount Irving, high, rises north of Cape Bowles, the southernmost point. The southeast slopes of the two ridges are drained by Dobrodan, Highton, Treskavets, Orcho, and Banari Glaciers, and their northwest slopes — by Skaplizo, Giridava, and Bersame Glaciers. There are two small islands just east of Clarence Is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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]   |

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ...

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.
