Lann Glacier
Lann Glacier () is a steep tributary glacier, long, in the north end of the Admiralty Mountains of Antarctica. The glacier is east of Rowles Glacier and flows northwest to enter Dennistoun Glacier. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Roy R. Lann, a U.S. Navy cook at Hallett Station Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Admiralty Mountains
The Admiralty Mountains (alternatively Admiralty Range) is a large group of high mountains and individually named ranges and ridges in northeastern Victoria Land, Antarctica. This mountain group is bounded by the Ross Sea, the Southern Ocean, and by the Dennistoun, Ebbe, and Tucker glaciers. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. It was discovered in January 1841 by Captain James Ross, who named them for the Lords Commissioners of the Admiralty under whose orders he served. The Admiralty Mountains are divided into the Dunedin Range, Homerun Range, and Lyttelton Range. Mountains and peaks This range includes the following mountains and peaks: Mount Achilles Mount Achilles is a prominent pyramidal mountain rising from the divide between Fitch Glacier and Man-o-War Glacier. Named by New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, after the former New Zealand cruiser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowles Glacier
Rowles Glacier () is a tributary glacier over 20 nautical miles (37 km) long, flowing northwest along the east side of Dunedin Range, Admiralty Mountains, to enter Dennistoun Glacier. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–63. Named by Advisory Committee on Antarctic Names (US-ACAN) for D.S. Rowles of the New Zealand Department of Scientific and Industrial Research, a member of the Hallett Station Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica.

Dennistoun Glacier
The Dennistoun Glacier is a glacier, long, draining the northern slopes of Mounts Black Prince, Royalist and Adam in the Admiralty Mountains of Victoria Land in Antarctica. It flows northwest between the Lyttelton Range and Dunedin Range, turning east on rounding the latter range to enter the sea south of Cape Scott. The coastal extremity of the glacier was charted in 1911–12 by the Northern Party, led by Victor Campbell, of the British Antarctic Expedition, 1910–13. The geographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. The glacier is named after Jim Dennistoun, a New Zealand alpinist who was in charge of the mules on board the '' Terra Nova'' on her way to Antarctica. The entire extent of the glacier was mapped by the U.S. Geological Survey from surveys and U.S. Navy aerial photography, 1960–63. The name Fowlie Glacier, which in fact refers to a tributary glacier, has sometimes been inadvertently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

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] |
Roy R
Roy is a masculine given name and a family surname with varied origin. In Anglo-Norman England, the name derived from the Norman ''roy'', meaning "king", while its Old French cognate, ''rey'' or ''roy'' (modern ''roi''), likewise gave rise to Roy as a variant in the Francophone world.

Hallett Station
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oil stored in several large tanks. This is an ongoing project which will take several years to complete. Antarctic Specially Protected Area An area of 74 ha is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.106 because it contains habitats with a rich and diverse range of ...
