Downham Peak ( 64°17′S58°54′W / 64.283°S 58.900°W / -64.283; -58.900 Coordinates: 64°17′S58°54′W / 64.283°S 58.900°W / -64.283; -58.900 ) is a rock pyramid at the south side of the mouth of Sjogren Glacier, Trinity Peninsula. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and was named by the UK Antarctic Place-Names Committee for Noel Y. Downham, a FIDS meteorological assistant at Hope Bay, who assisted in the triangulation of this area in 1961. [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.

Sjogren Glacier glacier in Antarctica

Sjogren Glacier is a glacier 12.5 miles (20 km) long in the south part of Trinity Peninsula, flowing southeast from Detroit Plateau to enter Prince Gustav Channel at the head of Sjögren Inlet, south of the terminus of Boydell Glacier. Discovered in 1903 by the Swedish Antarctic Expedition under Nordenskjold. He named it Hj. Sjogren Fiord after a patron of the expedition. The true nature of the feature was determined by the Falkland Islands Dependencies Survey (FIDS) in 1945.

Trinity Peninsula

Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base.

Leppard Glacier

Leppard Glacier is a large valley glacier draining east between the Aristotle Mountains and Voden Heights, and flowing into Scar Inlet north of Ishmael Peak, on the east coast of Graham Land, Antarctica. The glacier was first seen from the air and photographed in part by Hubert Wilkins on December 20, 1928, and was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955. It is now clear that, on the photographic evidence of his outward flight, Wilkins gave the name "Crane Channel" to this glacier, and that on his return flight he photographed what is now accepted as Crane Glacier, perhaps thinking that it was the same feature. Since Crane Glacier has been retained for the northern of these glaciers photographed by Wilkins, the UK Antarctic Place-Names Committee has named this feature for Norman A.G. Leppard, assistant surveyor with the FIDS, who surveyed this area in 1955.

King Edward Cove cove of South Georgia

King Edward Cove is a sheltered cove immediately southwest of Mount Duse, in the west side of Cumberland East Bay, South Georgia. This cove, frequented by early sealers at South Georgia, was charted by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskiöld. It was named in about 1906 for King Edward VII of the United Kingdom.

Ice Gate Glacier glacier in Antarctica

Ice Gate Glacier is a narrow hanging glacier, tributary to Astudillo Glacier, between rock spurs on the west slope of Dallmeyer Peak, Danco Coast, Antarctica. It was named by the Polish Antarctic Expedition in about 1992, probably from the gatelike appearance of the spurs at the junction of the two glaciers.

Achaean Range

Achaean Range is a mountain range rising to 1,370 metres (4,495 ft) in the central part of Anvers Island in the Palmer Archipelago. It is bounded on the east by Iliad Glacier and Trojan Range and on the west by Marr Ice Piedmont, and extends northwest from Mount Agamemnon for 10 kilometres (6 mi), curving northeast for a further 19 km (12 mi) to Mount Nestor. Surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955 and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the Achaeans, one of the opposing forces of the Trojan War in Homer's Iliad.

Bevin Glacier is a glacier 5 nautical miles (9 km) long, which flows east from the plateau escarpment on the east side of Graham Land into the northwest end of Cabinet Inlet between Attlee Glacier and Anderson Glacier. During December 1947 it was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition. It was named by the FIDS for Rt. Hon. Ernest Bevin, M.P., British Minister of Labour and National Service and member of the War Cabinet.

Mount Brading is a mountain topped by a snow peak, 4 nautical miles (7 km) east of the northeast corner of Larsen Inlet in Graham Land. It was surveyed by the Falkland Islands Dependencies Survey (FIDS) (1960–61) and named after Christopher G. Brading, a FIDS surveyor at Hope Bay (1959–60), who, with I. Hampton, R. Harbour, and J. Winham, made the first ascent of this mountain.

Breitfuss Glacier glacier in Antarctica

Breitfuss Glacier is a glacier 10 nautical miles (19 km) long, which flows southeast from Avery Plateau into Mill Inlet to the west of Cape Chavanne, 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 in 1947. It was named by the FIDS for Leonid Breitfuss, a German polar explorer, historian, and author of many polar bibliographies.

Nipple Peak is a 675 m (2,215 ft) peak standing 1.9 kilometres (1.2 mi) north-east of Channel Glacier in the northern part of Wiencke Island, in the Palmer Archipelago of Antarctica. It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache. The name, which suggests the shape of the feature, was given by the Falkland Islands Dependencies Survey (FIDS) who mapped the peak in 1944.

Wallend Glacier is a deeply entrenched glacier which drains eastward from Forbidden Plateau to join Green Glacier in northern Graham Land. Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1955. So named by United Kingdom Antarctic Place-Names Committee (UK-APC) because the glacier is walled in on three sides by the escarpment of Forbidden Plateau.

Frigga Peak

Frigga Peak is a peak, 1,570 metres (5,150 ft) high, which stands at the south side of Anderson Glacier on the east coast of Graham Land, Antarctica. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition in 1947. The FIDS named it after the Norse goddess Frigga, the "cloud spinner," because clouds were observed to form on the summit of this peak earlier than on any other feature in this vicinity.

Evans Peak

Evans Peak is a prominent rock peak, 3,950 metres (12,960 ft) high, standing 3 nautical miles (6 km) east-northeast of Mount Ostenso in the Sentinel Range of the Ellsworth Mountains, Antarctica. It overlooks Rumyana Glacier to the north and Patton Glacier to the south. The peak was named by the University of Minnesota Geological Party to these mountains, 1963–64, for John Evans, a geologist with the party.

The Fid is a sharp peak rising to 1,640 metres (5,380 ft) at the eastern side of the mouth of Cole Glacier in southern Graham Land, Antarctica. The peak was photographed from the air by the United States Antarctic Service on September 28, 1940 and was surveyed by the Falkland Islands Dependencies Survey in December 1958. The name, by the UK Antarctic Place-Names Committee, derives from its shape, which suggests the conical wooden pin used in splicing, known as a fid.

Green Glacier is a glacier on the east side of Graham Land, Antarctica, 15 nautical miles (28 km) long and 4 nautical miles (7 km) wide, flowing from the plateau northeast between Dugerjav Peak and Rugate Ridge, and then east into Vaughan Inlet next north of Pirne Peak and south of the terminus of Hektoria Glacier.

Tait, FIDS meteorological observer at Hope Bay in 1952 and 1953.

Slessor Peak is a mainly ice-covered peak, 2,370 m, standing at the southwest end of Bruce Plateau in Graham Land, close northwest of Gould Glacier. It rises about 300 m above the general level of the plateau ice sheet and has a steep rock face on its north side. First surveyed in 1946-47 by a Falkland Islands Dependencies Survey (FIDS) sledge party led by Robert S. Slessor, FIDS medical officer at Stonington Island, for whom the peak is named.

Karpf Point is a point along the north side of Mill Inlet, 3 nautical miles (6 km) south of Mount Vartdal, on the east coast of Graham Land, Antarctica. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition in 1947, and was named by the FIDS for Alois Karpf, librarian of the Kaiserliche and Konigliche Geographische Gesellschaft in Vienna and joint author of a polar bibliography.

Ravel Peak is an isolated peak, rising to about 1,300 m, surmounting Debussy Heights situated in the northern portion of Alexander Island, Antarctica. The peak is markedly pyramid shaped when viewed from the east side. First mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Maurice Ravel (1875–1937), French composer and in association with the nearby landforms named after composers in this area.
