Holtedahl Peaks
The Holtedahl Peaks () are a group of peaks and ridges lying northward of Steinskaret Gap and forming the northern portion of the Kurze Mountains, in Queen Maud Land, Antarctica. The name "Holtedahlfjella" was applied to the entire extent of the Kurze Mountains on a Norsk Polarinstitutt map of 1966, but the name Kurze has priority, having been given by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39. For the sake of historical continuity, Kurze Mountains has been retained as applied by Ritscher; the name Holtedahl Peaks is recommended for the elevations northward of Steinskaret Gap in these mountains. The name is for Professor Olaf Holtedahl, a noted Norwegian geologist who worked in the South Shetland Islands and the Palmer Archipelago Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula.

Kurze Mountains
The Kurze Mountains (german: Kurzegebirge) are a range of mainly bare rock peaks, ridges and mountains about long and wide in the Orvin Mountains of Queen Maud Land, Antarctica. The feature stands between the Drygalski Mountains on the west and the Gagarin Mountains and Conrad Mountains on the east. The Kurze Mountains were discovered and plotted from aerial photographs taken by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39, who named them for the director of the Naval Division of the former Marineleitung ( German Admiralty). They were remapped by the Norsk Polarinstitutt from surveys and aerial photos taken by the Sixth Norwegian Antarctic Expedition The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud Land in Antarctica.

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Third German Antarctic Expedition
New Swabia (Norwegian and german: Neuschwabenland) was a disputed Antarctic claim by Nazi Germany within the Norwegian territorial claim of Queen Maud Land and is now a cartographic name sometimes given to an area of Antarctica between 20°E and 10°W in Queen Maud Land. New Swabia was explored by Germany in early 1939 and named after that expedition's ship, , itself named after the German region of Swabia.McGonigal, David, Antarctica', frances lincoln ltd, 2009, , p. 367 Background Like many other countries, Germany sent expeditions to the Antarctic region in the late 19th and early 20th centuries, most of which were scientific. The late 19th century expeditions to the Southern Ocean, South Georgia, the Kerguelen Islands, and the Crozet Islands were astronomical, meteorological, and hydrological, mostly in close collaboration with scientific teams from other countries. As the 19th century ended, Germany began to focus on Antarctica. The first German expedition to Antarctica ...

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]   |

Mountains Of The Palmer Archipelago
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 ...

Ridges Of Graham Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
