Williamson Bluff
Williamson Bluff is a flat-topped bluff more than high near the head of Trail Inlet on the east coast of Graham Land. The upper part of the bluff is snow topped, but the sides are steep and rocky. The bluff extends from the east side of Bills Gulch, northeast of Mount Shelby Mount Shelby () is a mountain, 1,520 m, standing between Daspit Glacier and Bills Gulch at the head of Trail Inlet, on the east coast of Graham Land. Discovered by members of East Base of the United States Antarctic Service (USAS), 1939–41. I .... First photographed from aircraft by personnel of United States Antarctic Service (USAS) on a flight of September 28, 1940. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after the Rev. William Williamson (1804–75), British mathematician and lawyer who made one of the earliest measurements of the surface flow of a glacier, in Switzerland, 1844.

Bluff (geography)
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowman Coast
The Bowman Coast is the portion of the east coast of the Antarctic Peninsula between Cape Northrop and Cape Agassiz. It was discovered by Sir Hubert Wilkins in an aerial flight of December 20, 1928.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, 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 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

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.

Trail Inlet
Trail Inlet () is an ice-filled inlet which recedes southwest 15 nautical miles (28 km) between Three Slice Nunatak and Cape Freeman, on the east coast of Graham Land. The inlet was sighted by Sir Hubert Wilkins on his flight of December 20, 1928. The width of Graham Land is reduced to 20 nautical miles (37 km) between the heads of Trail Inlet and Neny Fjord. So named by the US-SCAN because it was a natural route of travel for flights and sledge trips from the East Base of the 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 presence in the A ...

Bills Gulch
Bills Gulch () is a glacier on the southeast side of Hemimont Plateau, the northern of two glaciers flowing east from the plateau upland into the head of Trail Inlet, on the east coast of Graham Land. This glacier was used by the sledge party under Paul H. Knowles which traversed the Antarctic Peninsula from the East Base of the United States Antarctic Service (USAS) on its way to Hilton Inlet in 1940. It was named by USAS for a lead dog that died at this point. The unlikely name has been approved because of its wide use on maps and in reports. Chacabuco Refuge Refuge Chacabuco () is an Antarctic refuge close to the San Martín Base, on which it depends. It is located in the area of the Bills Gulch glacier, on the Fallières Coast in the Antarctic Peninsula, and is administered by the Argentine Army. The refuge was inaugurated on November 21, 1956, as logistical support and is the one located at the highest altitude of all the Argentine Antarctica, at about above sea ...

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 presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related 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, and works with other federal agencies, the U.S. military, an ...

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
