Last updated

The Magnier Peaks ( 65°40′S64°18′W / 65.667°S 64.300°W / -65.667; -64.300 Coordinates: 65°40′S64°18′W / 65.667°S 64.300°W / -65.667; -64.300 ) are two mountain peaks, the higher at 1,345 metres (4,410 ft), surmounting the peninsula between Leroux Bay and Bigo Bay on the west coast of Graham Land, Antarctica. These peaks were discovered and named by the Fourth French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Peninsula A piece of land that is bordered by water on three sides but connected to mainland

A peninsula is a landform surrounded by water on the majority of its border while being connected to a mainland from which it extends. The surrounding water is usually understood to be continuous, though not necessarily named as a single body of water. Peninsulas are not always named as such; one can also be a headland, cape, island promontory, bill, point, or spit. A point is generally considered a tapering piece of land projecting into a body of water that is less prominent than a cape. A river which courses through a very tight meander is also sometimes said to form a "peninsula" within the loop of water. In English, the plural versions of peninsula are peninsulas and, less commonly, peninsulae.

Leroux Bay bay

Leroux Bay is a bay 9 nautical miles (17 km) long in a northwest–southeast direction and averaging 5 nautical miles (9 km) wide, between Nunez Point and the narrow Magnier Peninsula surmounted by the Magnier Peaks and Lisiya Ridge, along the west coast of Graham Land, Antarctica. The glaciers Chernomen, Luke and Muldava feed the bay.

It was discovered and named by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, probably for Commandant Alfonso Chaves of Ponta Delgada, Azores, but the spelling Chavez has become established through long usage.

Jeroboam Glacier glacier in Antarctica

Jeroboam Glacier is a southwestern tributary glacier in the north foothills of Mount Sara Teodora that joins Starbuck Glacier just east of Gabriel Peak in Aristotle Mountains, on the east side of Graham Land, Antarctica. The toponym is one of several in the vicinity applied by the UK Antarctic Place-Names Committee from Herman Melville's Moby-Dick, the Jeroboam being the ship that met the Pequod.

Drummond Glacier glacier in Antarctica

Drummond Glacier is a glacier 10 nautical miles (18 km) long and 2 nautical miles (4 km) wide, on the west coast of Graham Land, situated south of Hopkins Glacier and flowing west-northwest between Voit Peak and Sherba Ridge into Darbel Bay east of Sokol Point.

It was first surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1946–47, and named "West Gould Glacier". With East Gould Glacier it was reported to fill a transverse depression across Graham Land, but further survey in 1957 showed no close topographical alignment between the two. The name Gould has been limited to the east glacier and an entirely new name, for Angus B. Erskine, leader of the first FIDS party to travel down the glacier and to survey it in detail, has been approved for the west glacier.

Forecast, a weather observer at Wilkes Station, 1965.

Cape Garcia headland

Cape Garcia is a cape at the north side of the entrance to Barilari Bay, forming the north extremity of Felipe Solo (Obligado) Peninsula on the west coast of Graham Land, Antarctica. The cape was discovered and named "Cap Loqui" by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot. At the same time Charcot named the south entrance point to the bay "Cap Garcia," after Rear Admiral Garcia of the Argentine Navy. The maps of Charcot's French Antarctic Expedition, 1908–10, showed "Cap Garcia" as the north cape of Barilari Bay and the name has since become established for this feature. Charcot did not use the name "Cap Loqui" on the maps of his second expedition but, for the sake of historical continuity, the name Loqui Point has been accepted for the south entrance point.
