Blankenship Glacier
Ferrar Glacier ()is a glacier in Antarctica. It is about long, flowing from the plateau of Victoria Land west of the Royal Society Range to New Harbour in McMurdo Sound. The glacier makes a right (east) turn northeast of Knobhead, where it where it is apposed, i.e., joined in Siamese-twin fashion, to Taylor Glacier. From there, it continues east along the south side of Kukri Hills to New Harbor. Discovery and naming Ferrar Glacier was discovered by the British National Antarctic Expedition, (1901–04) under Captain Robert Falcon Scott, who named this feature for Hartley T. Ferrar, geologist of the expedition. The name Ferrar Glacier was originally applied both to the part of this glacier below its right turn and to the present Taylor Glacier. Thomas Griffith Taylor, geologist of the British Antarctic Expedition, 1910–13, under Scott, found evidence that these are not two parts of a single glacier but are two glaciers apposed. With this discovery Scott gave the names Ferrar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78th parallel south, 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Victoria of the United Kingdom, Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent between 26,000 and 20,000 years ago. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels. Based on changes in position of ice sheet margins dated via cosmogenic nuclide, terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets in the southern hemisphere commenced 33,000 years ago and maximum coverage has been estimated to have occurred sometime between 26,500 years ago and 20,000 years ago. After this, deglaciation caused an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fl ...

Mount Coates (Victoria Land)
Kukri Hills () is a prominent east-west trending range, about long and over high, forming the divide between Ferrar Glacier on the south and Taylor Glacier and Taylor Valley on the north, in Victoria Land, Antarctica. They are south of the Asgard Range, east of the Quartermain Mountains and north of the Royal Society Range. The hills were discovered by the Discovery Expedition (1901–04) and probably so named because its shape resembles that of the Kukri, a Gurkha knife. Topography The western tip of the Kukri Hills is Mount Brearley, where the Taylor Glacier separates from the Ferrar Glacier, with the Taylor Glacier flowing north east and the Ferrar glacier flowing southeast. The hills stretch east with, with prominent peaks from west to east including Mount Coates, Sentinel Peak, Bonney Riegel, Nussbaum Regel, Andrew's Ridge, and Mount Barnes where the hills terminate in New Harbor. The Taylor Glacier and Taylor Valley run along the north side, while the Ferrar Glacier run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pivot Peak
The Wilkniss Mountains () form a prominent group of conical peaks and mountains, long running north–south, located east-southeast of Mount Feather in the Quartermain Mountains, Victoria Land, Antarctica. The mountains are wide in the north portion where Mount Blackwelder, high, and Pivot Peak high, rise above ice-free valleys. Except for an outlying southwest peak, the south portion narrows to a series of mainly ice-covered smaller peaks. Name The Wilkniss Mountains were named by United States Advisory Committee on Antarctic Names (US-ACAN) in 1992 after Peter E. Wilkniss, a chemist who from 1975 has served in various positions at the National Science Foundation, including Deputy Assistant Director of the Directorate for Scientific, Technological, and International Affairs; Director, Division of Polar Programs, 1984–93; senior science associate to the assistant director for Geosciences, from 1993.

Mount Feather
The Quartermain Mountains ( ) are a group of exposed mountains in Antarctica, about long, typical of ice-free features of the McMurdo Dry Valleys, Victoria Land. They are east of the Lashly Mountains, south of the Asgard Range, west of the Kukri Hills and Royal Society Range, and some distance north of the Worcester Range. Exploration The Quartermain Mountains were visited by British expeditions led by Robert Falcon Scott (1901–04 and 1910–13) and Ernest Shackleton (1907–09), who applied several names. Names were added in the years subsequent to the International Geophysical Year, 1957–58, concurrent with research carried out by New Zealand Antarctic Research Programme (NZARP) and United States Antarctic Research Program (USARP) field parties, and to fulfill the requirement for maps compiled from United States Navy aerial photographs, 1947–83. In 1977, the New Zealand Antarctic Place-Names Committee named the mountains after New Zealand Antarctic historian Lester B ...

Lashly Mountains
The Lashly Mountains () are a small group of mountains, the most prominent at being Mount Crean, standing south of the head of Taylor Glacier and west of Lashly Glacier, in Victoria Land, Antarctica. Exploration and naming The Lashly Mountains were discovered by the British National Antarctic Expedition (1901–04) and named for William Lashly, a member of the party which explored this area. Location The Lashley Mountains are on the edge of the East Antarctic Ice Sheet. They are west of the Quartermain Mountains and Mount Feather, from which they are separated by the Lashly Glacier, which flows south into The Portal. Mount Crean is the highest peak of the range. Portal Mountain lies to the south of the range, above the Skelton Névé. Geology The Lashly Mountains lie between the intrusive rocks of the McMurdo Dry Valleys and the extrusive rocks of the Transantarctic Mountains. Samples from an unnamed nunatak north of Mount Crean indicated an extrusive origin. The Lashly Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Crean
Mount Crean is one of the westernmost peaks in the dry valley region of South Victoria Land in Antarctica. It lies at , rises to , and is the highest summit in the Lashly Mountains. It is named after the Irish explorer Tom Crean, who was a member of both of Captain Scott's Antarctic expeditions ( Discovery, 1901–04 and Terra Nova, 1910–13), and served as second officer on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition, 1914–17. In the 2000–01 summer season a meteorite was found on Mount Crean by a geological party.

Butter Point
New Harbour () is a bay about wide between Cape Bernacchi and Butter Point along the coast of Victoria Land, due west of Ross Island. Exploration and naming New Harbour was discovered by the British National Antarctic Expedition (BrNAE; 1901–04) and so named because this new harbor was found while the ''Discovery'' was seeking the farthest possible southern anchorage along the coast of Victoria Land. Location New Harbour opens into McMurdo Sound opposite Ross Island, between Cape Bernacchi to the north and Butter Point to the south. The Wilson Piedmont Glacier is to the north of New Harbour and the Bowers Piedmont Glacier is to the south. To the west, the Kukri Hills extend into the harbour to the north of Ferrar Glacier, which empties into the harbour. Features Features include, from north to south, include: Cape Bernacchi . A rocky cape between Bernacchi Bay and New Harbor. Discovered by the BrNAE, 1901-04, under Scott, and named by him for Louis C. Bernacchi, phys ...
