Mount Bigo ( 65°46′S64°17′W / 65.767°S 64.283°W / -65.767; -64.283 Coordinates: 65°46′S64°17′W / 65.767°S 64.283°W / -65.767; -64.283 ) is a 1,980 m mountain in Lisiya Ridge on Magnier Peninsula, Graham Coast in Graham Land, standing immediately southwest of Mount Perchot at the head of Bigo Bay. It was discovered by the French Antarctic Expedition of 1908–10 and named by Charcot probably for Robert Bigo of Calais, a member of the Ligue Maritime Française.

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.

Mountain A large landform that rises fairly steeply above the surrounding land over a limited area

A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges.

Lisiya Ridge

Lisiya Ridge is the ice-covered ridge at the base of Magnier Peninsula, Graham Coast on the west side of Antarctic Peninsula, extending 16 km in northeast-southwest direction between the heads of Leroux Bay and Bigo Bay, and 11 km wide. Bounded by Comrie Glacier to the south and a tributary to Luke Glacier to the east. Featuring Mount Bigo at its southwest extremity and Mount Perchot in its central part. Precipitous, partly ice-free northwest slopes drained by the glaciers Muldava, Nesla and Kolosh.

Aagaard Glacier glacier in Antarctica

Aagaard Glacier, also known as Glaciar Alderete, is an 8-mile (13 km) long Antarctic glacier which lies close to the east of Gould Glacier and flows in a southerly direction into Mill Inlet, on the east coast of Graham Land. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition during December 1947; it was named by the FIDS for Bjarne Aagaard, a Norwegian authority on Antarctic whaling and exploration.

Bigo Bay bay

Bigo Bay is a bay 8 nautical miles (15 km) long and 6 nautical miles (11 km) wide, indenting the west coast of Graham Land between Cape Garcia and Magnier Peninsula surmounted by the Magnier Peaks and Lisiya Ridge.

Nesla Glacier is the 6.2 km long and 2 km wide glacier on Magnier Peninsula, Graham Coast on the west side of Antarctic Peninsula, situated southwest of Muldava Glacier and north of Kolosh Glacier. It drains the west slopes of Lisiya Ridge west of Mount Perchot, and flows westwards into Bigo Bay next north of the terminus of Kolosh Glacier.

Kolosh Glacier is the 6.7 km long and 3.6 km wide glacier on Magnier Peninsula, Graham Coast on the west side of Antarctic Peninsula, situated south of Nesla Glacier. It drains the west slopes of Lisiya Ridge north of Mount Bigo, and flows northwestwards into Bigo Bay next south of the terminus of Nesla Glacier.

Chavez Island

Chavez Island is an island 3 nautical miles (6 km) long which rises to 550 metres (1,800 ft), lying immediately west of Magnier Peninsula, which is between Leroux Bay and Bigo Bay, off the west coast of Graham Land. 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.

Mount Chevreux is a mountain, 1,615 metres (5,300 ft) high, standing 5 nautical miles (9 km) southeast of Leroux Bay on the west coast of Graham Land. It was discovered by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who named it for Edouard Chevreux, a French zoologist.

Comrie Glacier is a glacier 13 nautical miles (24 km) long, flowing west to enter the head of Bigo Bay on the west coast of Graham Land. It was first sighted and roughly surveyed by the French Antarctic Expedition in 1909. It was resurveyed in 1935–36 by the British Graham Land Expedition (BGLE), and later named for Leslie J. Comrie, founder and first Director of the Scientific Computing Service Ltd, London, who, as Superintendent of HM Nautical Almanac Office in 1934, greatly assisted the BGLE, 1934–37, by providing advance copies of The Nautical Almanac up to 1937.

Mount Demaria mountain in Antarctica

Mount Demaria is a mountain with precipitous sides, 635 metres (2,080 ft) high, rising immediately southeast of Cape Tuxen on the west coast of Kiev Peninsula in Graham Land. It was probably first sighted by the Belgian Antarctic Expedition of 1897–99. It was charted by the French Antarctic Expedition of 1903–05 and was named by Jean-Baptiste Charcot for the Demaria brothers, French developers of an anastigmatic lens used by the expedition's photographic section.

Funk Glacier glacier in Antarctica

Funk Glacier is a glacier flowing into the head of Nevsha Cove in Beascochea Bay to the south of Frölich Peak, on the west coast of Graham Land, Antarctica. It was first charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot. It was named by the UK Antarctic Place-Names Committee in 1959 for Casimir Funk, an American biochemist who, while working at the Lister Institute in London in 1912, originated the theory of vitamins.

Greenshields Peak is a peak between Leroux Bay and Bigo Bay, rising 1 nautical mile (2 km) west of the Magnier Peaks on the west coast of Graham Land, Antarctica. It was mapped by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57, and was named by the UK Antarctic Place-Names Committee for James N.H. Greenshields, a pilot with the Falkland Islands and Dependencies Aerial Survey Expedition in this area, 1955–56.

Portal Point Refuge in United Kingdom

Portal Point is a narrow point in the northeast part of Reclus Peninsula, on the west coast of Graham Land. In 1956, a Falkland Islands Dependencies Survey (FIDS) hut was established on the point, from which a route to the plateau was established. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 because the point is the "gateway" of the route.

The Fontaine Heights are a line of heights that extend from Mount Dewey to Cape Garcia on the south side of Bigo Bay, on the west coast of Graham Land, Antarctica. They were mapped from air photos and Falkland Islands Dependencies Survey surveys from 1955–57, and they were named by the UK Antarctic Place-Names Committee for Henri La Fontaine, a Belgian documentalist. Fontaine was the co-founder of Institut International de Bibliographie at Brussels in 1895, and he was the co-founder of the Office Central des Associations Internationales at Brussels in 1907. He was an initiator of the Universal Decimal Classification.

The Forge Islands are a group of small islands lying northeast of The Barchans and 0.5 nautical miles (1 km) northwest of Grotto Island, in the Argentine Islands, Wilhelm Archipelago. They were charted and named the "Horseshoe Islands" by the British Graham Land Expedition under John Rymill, 1934–37. The name was changed by the UK Antarctic Place-Names Committee in 1959 to avoid confusion with Horseshoe Island in Marguerite Bay. This new name arises from association with the old name and with nearby Anvil Rock.
