Olds Peak
The Prince Olav Mountains () is a mountain group in the Queen Maud Mountains in Antarctica stretching from Shackleton Glacier to Liv Glacier at the head of the Ross Ice Shelf. Discovery and naming The Prince Olav Mountains were discovered in 1911 by Roald Amundsen on the way to the South Pole, and named by him for the then Crown Prince Olav of Norway. Main peaks This range includes the following high mountains and peaks: Location The Prince Olav Mountains extend in a generally northwest – southeast direction between the Shackleton Glacier to the west and the Liv Glacier to the east.

Ultra-prominent Peak
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,500 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and thus do not achieve enough topographic prominence. The term "ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, over 1,500 ultras have been identified above sea level: 654 in Asia, 357 in North America, 209 in South America, 119 in Europe (including 12 in the Caucasus), 84 in Africa, 54 in Oceania, and 39 in Antarctica.

Yeats Glacier
Shackleton Glacier () is a major Antarctic glacier, over long and from wide, descending from the Antarctic Plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs. Discovered by the United States Antarctic Service (USAS) (1939–41) and named by the Advisory Committee on Antarctic Names (US-ACAN) for Sir Ernest Shackleton, British Antarctic explorer. Course The Shackleton Glacier originates in the East Antarctic Ice Sheet and flows northeast between Dismal Buttress to the northwest and Roberts Massif to the southeast. It is joined from the right (east) by Zaneveld Glacier, which also originates in the ice sheet. Further north it is joined from the right by the Logie Glacier, which flows west through the Cumulus Hills. Flowing north, the Shackleton Glacier is joined from the left (west) by the Gallup Glacier and the Baldwin Glacier and from the right (east) by McGregor ...

Texas Longhorn
The Texas Longhorn is an American breed of beef cattle, characterized by its long horns, which can span more than from tip to tip. It derives from cattle brought from the Iberian Peninsula to the Americas by Spanish conquistadors from the time of the Second Voyage of Christopher Columbus until about 1512. For hundreds of years the cattle lived a semi-feral existence on the rangelands; they have a higher tolerance of heat and drought than most European breeds. The coat can be of any color or mix of colors; in some 40% of the cattle it is some shade of red, often a light red. In the twenty-first century, the Longhorn is considered a part of the cultural heritage of Texas. History The Texas Longhorn derives from cattle brought to the Americas by Spanish conquistadors from the time of the Second Voyage of Christopher Columbus until about 1512. The first cattle were landed in 1493 on the Caribbean island of La Isla Española (now known as Hispaniola) to provide food for ...

United States Navy Reserve
The United States Navy Reserve (USNR), known as the United States Naval Reserve from 1915 to 2004, is the Reserve Component (RC) of the United States Navy. Members of the Navy Reserve, called reservists, are categorized as being in either the Selected Reserve (SELRES), the Training and Administration of the Reserve (TAR), the Individual Ready Reserve (IRR), or the Retired Reserve. Organization The mission of the Navy Reserve is to provide strategic depth and deliver operational capabilities to the Navy and Marine Corps team, and to the Joint forces, in the full range of military operations from peace to war. The Navy Reserve consists of 56,254 officers and enlisted personnel who serve in every state and territory as well as overseas as of June 2023. Selected Reserve (SELRES) The largest cohort, the Selected Reserve (SELRES), have traditionally drilled one weekend a month and performed two weeks of active duty annual training during the year, receiving base pay and certai ...

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] |
United States Antarctic Service
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has a presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. Research stations in Antarctica, scientific research and related Transport in Antarctica, logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, ...

Zotikov Glacier
Liv Glacier () is a steep valley glacier, long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and Duncan Mountains. It was discovered in 1911 by Roald Amundsen, who named it for the daughter of Fridtjof Nansen. Richard E. Byrd chose this glacier as his route to the Polar Plateau on 28 November 1929 when he flew from Little America to the South Pole. Location According to ''Sailing Directions for Antarctica'' (1960), "The Liv Glacier (85° S. 168° W.) reaches the Ross Ice Shelf on the western side of the Duncan Mountains. It is about 7 miles wide and trends southward about 40 miles to the polar plateau. The Fisher Mountains rise prominently forming the western wall, and the massif of Mount Fridtjof Nansen, about 13,156 feet high, forms the eastern flank of the Liv Glacier. The northern slopes of this sandstone and granite massif were investigated by Gould i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
