Morse Nunataks
The Colbert Hills () are a line of hills and bluffs, including Coalsack Bluff, lying east of Lewis Cliffs, between Law Glacier and Walcott Névé in Antarctica. The hills trend southwest for from Mount Sirius. Exploration and name The Colbert Hills are named for Edwin H. Colbert, curator of vertebrate paleontology at the American Museum of Natural History, leader of the paleontology team with the Ohio State University Geological Expedition, 1969–70, which discovered ''Lystrosaurus'' fossils in these hills. The discovery is one of the truly significant fossil finds, with great implications on calculations concerning Gondwanaland. Location The Colbert Hills are to the east of the Antarctic Plateau and south of Law Glacier, which separates them from the Queen Elizabeth Range. The Walcott Névé is to the south, and the Queen Alexandra Range to the east. Features include Coalsack Bluff, Bauhs Nunatak and Mount Sirius. Nearby features to the west include Jacobs Nunatak, Morse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Law Glacier
Lennox-King Glacier is a large valley glacier, about long that flows east into the Ross Ice Shelf. Location Lennox-King Glacier drains Bowden Névé and flows northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet and the Ross Ice Shelf. The Law Glacier supplies ice to the Lennox-King Glacier, leading some glaciologists to refer to it as the Law/Lennox-King Glacier system or Law-Lennox-King glacier corridor. Its mouth is south of the Robb Glacier and west of the Beardmore Glacier. Lennox-King Glacier was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base, 1960. Mouth Richards Inlet . A large ice-filled inlet at the mouth of Lennox-King Glacier, opening to the Ross Ice Shelf just southeast of Lewis Ridge. Named by the NZGSAE (1959–60) for R. W. Richards, a member of the Ross Sea Party of the Imperial Trans-Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lystrosaurus
''Lystrosaurus'' (; 'shovel lizard'; proper Ancient Greek is ''lístron'' ‘tool for leveling or smoothing, shovel, spade, hoe’) is an extinct genus of herbivorous dicynodont therapsids from the late Permian and Early Triassic epochs (around 248 million years ago). It lived in what is now Antarctica, India, China, Mongolia, European Russia and South Africa. Four to six species are currently recognized, although from the 1930s to 1970s the number of species was thought to be much higher. They ranged in size from that of a small dog to 8 feet (2.5 meters) long. As a dicynodont, ''Lystrosaurus'' had only two teeth (a pair of tusk-like canines), and is thought to have had a horny beak that was used for biting off pieces of vegetation. ''Lystrosaurus'' was a heavily built, herbivorous animal. The structure of its shoulders and hip joints suggests that ''Lystrosaurus'' moved with a semi-sprawling gait. The forelimbs were even more robust than the hindlimbs, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwanaland
Gondwana ( ; ) was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian subcontinent. Gondwana was formed by the accretion of several cratons (large stable blocks of the Earth's crust), beginning with the East African Orogeny, the collision of India and Madagascar with East Africa, and culminating in with the overlapping Brasiliano and Kuunga orogenies, the collision of South America with Africa, and the addition of Australia and Antarctica, respectively. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of some , about one-fifth of the Earth's surface. It fused with Laurasia during the Carboniferous to form Pangaea. It began to separate from northern Pangea (Laurasia) during the Triassic, and started to fragment during the Early ...

Antarctic Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the '' Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his '' Nimrod'' Expedition, which turned back in bad weather when it had reached a point from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway.

Queen Elizabeth Range (Antarctica)
The Queen Elizabeth Range () is a rugged mountain range that parallels the eastern side of Marsh Glacier for nearly from Nimrod Glacier in the north to Law Glacier in the south. Mount Markham, high, is the highest elevation in the range. Name The Queen Elizabeth Range was named by J.H. Miller of the New Zealand party of the Commonwealth Trans-Antarctic Expedition (CTAE; 1956–58) who, with G.W. Marsh, explored this area. It was named for Queen Elizabeth II of Great Britain, the patron of the expedition. Location The Queen Elizabeth Range is bounded to the north by the Nimrod Glacier, which separates it from the Churchill Mountains and Nash Range. To the east the Lowery Glacier and Robb Glacier separate it from the Holland Range. The Law Glacier to the south separates its from the Colbert Hills (Antarctica), Colbert Hills and Queen Alexandra Range. The Marsh Glacier separates it from the Miller Range to the west.

Queen Alexandra Range
The Queen Alexandra Range () is a major mountain range about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau to the Ross Ice Shelf. The range is in the Transantarctic Mountains System, and is located in the Ross Dependency region of Antarctica. Discovery The Queen Alexandra Range was discovered on the journey toward the South Pole by the British Antarctic Expedition, 1907–09 (BrAE), and was named by Ernest Shackleton for Queen Alexandra, Queen of the United Kingdom, 1901-10. Shackleton and his men, and a later expedition headed by Robert Falcon Scott, both collected rock samples from the range that contained fossils. The discovery that multicellular life forms had lived so close to the South Pole was an additional piece of evidence that accompanied the publication (in 1910 and independently in 1912) of the theory of continental drift. Location The Queen Alexandra Range is bounded by the Beardmore Glacier along its southeast edge, which divi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
