Lizard Nunatak
Lizard Nunatak () is a nunatak rising to about situated within the Nichols Snowfield, in the northern portion of Alexander Island, Antarctica. It is situated 12 km east by north of Mount Kliment Ohridski and 9 km south-southeast of the summit of Landers Peaks in Sofia University Mountains, and 6.4 km southwest of Serpent Nunatak and 9.38 km north by west of Tegra Nunatak in Rouen Mountains. The feature was so named by the UK Antarctic Place-Names Committee in 1977 from its shape and in association with Serpent Nunatak lying to the northeast.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nichols Snowfield
Nichols Snowfield () is a snowfield, 22 nautical miles (41 km) long and 8 nautical miles (15 km) wide, bounded by the Rouen Mountains and Elgar Uplands to the east and Lassus Mountains to the west, in the north part of Alexander Island, Antarctica. The snowfield was first sighted from the air and roughly mapped by the British Graham Land Expedition (BGLE) in 1937. Mapped in detail from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the RARE for Dr. Robert L. Nichols, head of the Department of Geology, Tufts University Tufts University is a private research university on the border of Medford and Somerville, Massachusetts. It was founded in 1852 as Tufts College by Christian universalists who sought to provide a nonsectarian institution of higher learning. ..., and senior scientist of the Ronne expedition.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landers Peaks
The Landers Peaks () are a group of peaks east of Mount Braun, rising to about between Palestrina Glacier and Nichols Snowfield in the northern portion of Alexander Island, Antarctica. They were named by the Advisory Committee on Antarctic Names for Commander Robert J. Landers, U.S. Navy, an LC-130 aircraft pilot in Squadron VXE-6 during U.S. Navy Operation Deep Freeze, 1965 and 1966.

Sofia University Mountains
Sofia University Mountains (планина Софийски Университет \pla-ni-'na so-'fiy-ski u-ni-ver-si-'tet\) are a cluster of four small mountains, long in the southwest-northeast direction and wide, rising to ca. (Mount Kliment Ohridski) in northern Alexander Island. They are located south-southeast of Havre Mountains, southwest of Rouen Mountains, northwest of Elgar Uplands, east of the northern part of Lassus Mountains, and inland from Lazarev Bay. Bounded by Palestrina Glacier to the north, Nichols Snowfield to the southeast, and McManus Glacier to the west. The mountains comprise Mount Braun to the northwest, Balan Ridge to the north and Landers Peaks to the northeast, and the ridge of Mount Kliment Ohridski to the south. The former three mountains are divided by Yozola Glacier flowing northwards to join Palestrina Glacier, and the long, ice-filled Poste Valley respectively. The name is of national culture and was given in commemoration of the ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serpent Nunatak
Serpent Nunatak () is a nunatak which is seen in the shape of a reverse letter S, rising to about just west of Tufts Pass lying within the Nichols Snowfield, in the northern portion of Alexander Island, Antarctica. It is situated northeast of Lizard Nunatak and south of Lesnovo Hill. The feature was descriptively named by United Kingdom Antarctic Place-Names Committee in 1977 because of the nunataks shape, the reverse letter S supposedly resembles a Serpent.

Rouen Mountains
The Rouen Mountains () are a prominent mountain range, reaching to about 2,800 m and extending 35 miles (60 km) NW-SE from Mount Bayonne to Care Heights and Mount Cupola, in north Alexander Island, Antarctica. This mountain range is known to occupy some of the highest peaks of Alexander Island, much like the nearby Douglas Range. Mount Paris is the highest point of the Rouen Mountains, exceeding 2,800 m approximately. The mountains were first mapped by the French Antarctic Expedition of 1908–10, under J. B. Charcot and named by him after the French city of Rouen. Charcot indicated a break in these mountains south of Mount Paris, but air photos taken by the Ronne Antarctic Research Expedition of 1947–48, as interpreted by Searle of the Falkland Islands Dependencies Survey (FIDS) indicate that the mountains are continuous southeast to Mount Cupola. They were partly surveyed by FIDS in 1948 and further delineated from U.S. satellite imagery of January 1974 and February 19 ...

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.
