Holmes Hills
The Holmes Hills () are a group of ridges and nunataks rising to about between Runcorn Glacier and Beaumont Glacier, bounded to the southwest by the Brennecke Nunataks, in south-central Palmer Land, Antarctica. They were mapped by the United States Geological Survey from aerial photographs taken by the U.S. Navy, 1966–69, and surveyed by the British Antarctic Survey, 1972–73. In association with the names of continental drift scientists grouped in this area, the hills were named by the Advisory Committee on Antarctic Names in 1978 after Scottish geologist Arthur Holmes, Professor of Geology at the University of Edinburgh The University of Edinburgh (, ; abbreviated as ''Edin.'' in Post-nominal letters, post-nominals) is a Public university, public research university based in Edinburgh, Scotland. Founded by the City of Edinburgh Council, town council under th ..., 1943–56. References Ridges of Palmer Land Nunataks of Palmer Land {{PalmerLand-geo-stub ...

Nunatak
A nunatak (from Inuit language, Inuit ) 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 often form natural pyramidal peaks. Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term ''nunatak'' is typically used in areas where a permanent ice sheet is present and the ridge protrudes 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 are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on thei ...

Runcorn Glacier
Hilton Inlet () is an ice-filled inlet, wide, which recedes about west from its entrance between Cape Darlington and Cape Knowles, along the east coast of Palmer Land, Antarctica. Location Hilton Inlet is on the east coast of Palmer Land, north of Violante Inlet and Schott Inlet, and south of Odom Inlet. The Merz Peninsula and Wilson Mountains are to the south, the Hess Mountains are to the west, and the Condor Peninsula is to the north. Glaciers feeding the inlet include, clockwise from the south, Spiess Glacier, Beaumont Glacier and its left tributary Runcorn Glacier, Gruening Glacier and its left tributary Kellogg Glacier. Other features, clockwise from the south, include Cape Darlington, Dietz Bluff, Boyer Spur, Malva Bluff and Cape Knowles. Discovery and name Hilton Inlet was discovered by the United States Antarctic Service (USAS) in 1940, and named for Donald C. Hilton, a member of the East Base sledge party that charted this coast as far south as this inlet. Gla ...

Brennecke Nunataks
The Brennecke Nunataks () are a group of large nunataks on the north side of the head of Beaumont Glacier, to the southwest of the Holmes Hills in south-central Palmer Land. They were mapped by the United States Geological Survey from aerial photographs taken by the U.S. Navy, 1966–69. In association with the names of oceanographers grouped in this area, the group was named by the UK Antarctic Place-Names Committee after Carl Wilhelm A. Brennecke (1875–1924), German oceanographer; member of the staff of Deutsche Seewarte ( German Naval Observatory), 1904–24; member of the Second German Antarctic Expedition The Second German Antarctic Expedition of 1911–1913 was led by Wilhelm Filchner in the exploration ship . Its principal objective was to determine whether the Antarctic continent comprised a single landmass rather than separated elements, and ..., 1911–12.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner–Ronne Ice Shelf, Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula a ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of list of global issues, global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the British Admiralty, Admiralt ...

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 ...

Arthur Holmes
Arthur Holmes (14 January 1890 – 20 September 1965) was an English geologist who made two major contributions to the understanding of geology. He pioneered the use of radiometric dating of minerals, and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics. Life He was born in Hebburn, County Durham, near Newcastle upon Tyne, the son of David Holmes, a cabinet-maker, and his wife, Emily Dickinson. As a child, he lived in Low Fell, Gateshead, and attended the Gateshead Higher Grade School (later Gateshead Grammar School). At 17, he enrolled to study physics at the Royal College of Science (now Imperial College London), but took a course in geology in his second year, which settled his future, against the advice of his tutors. After graduation, he took a job prospecting for minerals in Mozambique. After six months, with no discoveries, he became so ill with malaria that ...

Ridges Of Palmer Land
A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements. Classification As in the case of landforms in general, there is a lack of any commonly agreed classi ...
