Bowers Mountains
__NOTOC__ Bowers Mountains () is a group of north–south trending mountains in Antarctica, about 145 km (90 mi) long and 56 km (35 mi) wide, bounded by the coast on the north and by the Rennick, Canham, Black and Lillie glaciers in other quadrants. The seaward end was first sighted in February 1911 from the ''Terra Nova'', under Lt. Harry L.L. Pennell, RN, and was subsequently named "Bowers Hills" in honour of Henry Robertson Bowers who perished with Captain Robert Falcon Scott on their return from the South Pole in 1912. The mountain range is one of the most extensive topographical features within Victoria Land. The feature was photographed from U.S. Navy aircraft in 1946-47 and 1960–62, and was surveyed and mapped by the United States Geological Survey (USGS) in 1962–63. The name was amended to Bowers Mountains upon USGS mapping which showed the group to be a major one with peaks rising to nearly 2,600 metres. The major topographical feature lies si ...

Sledgers Glacier
Rennick Glacier is broad glacier, nearly long, which is one of the largest in Antarctica. It rises on the polar plateau westward of Mesa Range and is wide, narrowing to near the coast. It takes its name from Rennick Bay where the glacier reaches the sea. The seaward part of the glacier was photographed by U.S. Navy (USN) Operation Highjump, 1946–47. The upper reaches of the Rennick Glacier were discovered and explored by the U.S. Victoria Land Traverse (VLT) in February 1960, and the first ascent made of Welcome Mountain by John Weihaupt, Alfred Stuart, Claude Lorius and Arnold Heine of the VLT party. On February 10, 1960, Lieutenant Commander Robert L. Dale, pilot of U.S. Navy (USN) Squadron VX-6, evacuated the VLT from 7238S, 16132E, on this glacier, and then conducted an aerial photographic reconnaissance to Rennick Bay on the coast before returning the VLT team to McMurdo Station.

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] |

Eureka Spurs
The Eureka Spurs () are several rock spurs exposed along the east side of the head of Mariner Glacier, southwest of Mount McCarthy, in Victoria Land. They were so named, after the ancient Greek word eureka, by the Victoria University of Wellington Antarctic Expedition field party to Evans Neve, 1971–72, on the occasion of fossil discoveries made in the area. Thick sections of sedimentary strata of the Spurs Formation are exposed in Eureka Spurs. These outcrops exposed Cambrian submarine channel-fills in the Spurs Formation that exhibit unique meter-scale sedimentary cyclic layers of breccia and diamictite.Kim, Y.H.G., Woo, J., Park, T.Y.S., Kihm, J.H., Lee, J.I. and Choe, M.Y., 2018.
