Deep Freeze Range
The Deep Freeze Range () is a rugged mountain range, over long and about wide, rising between Priestley and Campbell Glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and mid portions of the range were observed by early British expeditions to the Ross Sea. The range was mapped in detail by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1955-63. It was named by the Advisory Committee on Antarctic Names in recognition of the support to research provided by the U.S. Navy's Operation Deep Freeze expeditions to Antarctica for many years beginning in 1954. __NOTOC__ Geological features Mount Adamson Mount Adamson () is a peak, high, rising east-northeast of Mount Hewson. It was named by the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1965–66, for R. Adamson, a geologist with this party. Mount Dickason Mount Dickason () i ...

Campbell Glacier
Campbell Glacier () is a glacier, about long, originating near the south end of Mesa Range and draining southeast between the Deep Freeze Range and Mount Melbourne to discharge into north Terra Nova Bay. The lower end of the glacier was observed by the Northern Party, led by Lieutenant Victor Campbell, Royal Navy, of the British Antarctic Expedition, 1910–13; it was named for the leader of this party. The extent of the glacier and its discharge into north Terra Nova Bay, rather than the Nansen Ice Sheet, was determined by United States and New Zealand survey parties to the area in 1961–62 and 1962–63. The steep bluff along the east side of the glacier is known as Hades Terrace, Bier Point is a projecting headland on the eastern side of Campbell Glacier.

Southern Cross Mountains
Southern Cross Mountains is the name applied to the group of Antarctic mountain ranges lying between the Mariner and Priestley Glaciers in Victoria Land. Seaward parts of this area were first viewed by Ross in 1841 and subsequently by expeditions led by Borchgrevink, Scott, Shackleton and Byrd. The precise mapping of its overall features was accomplished from U.S. Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. Named by the northern party of NZGSAE, 1965–66. Features Geographical features of Southern Cross Mountains include: Arrowhead Range Other features * Archambault Ridge * Aviator Glacier * Chisholm Hills * Cosmonette Glacier * Daughtery Peaks * Hades Terrace * Linn Mesa Linn Mesa () is a small mesa located south of the Chisholm Hills in the Southern Cross Mountains of Victoria Land, Antarctica.

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 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 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. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites A meteorite is a solid piece of debris from an ... [...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.

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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John L
John Lasarus Williams (29 October 1924 – 15 June 2004), known as John L, was a Welsh nationalist activist. Williams was born in Llangoed on Anglesey, but lived most of his life in nearby Llanfairpwllgwyngyll. In his youth, he was a keen footballer, and he also worked as a teacher. His activism started when he campaigned against the refusal of Brewer Spinks, an employer in Blaenau Ffestiniog, to permit his staff to speak Welsh. This inspired him to become a founder of Undeb y Gymraeg Fyw, and through this organisation was the main organiser of ''Sioe Gymraeg y Borth'' (the Welsh show for Menai Bridge using the colloquial form of its Welsh name).Colli John L Williams , '''', ...

Ridges Of Victoria Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
