Gavlpiggen Peak ( 73°58′S5°47′W / 73.967°S 5.783°W / -73.967; -5.783 Coordinates: 73°58′S5°47′W / 73.967°S 5.783°W / -73.967; -5.783 ) is a low, isolated peak 2 nautical miles (4 km) southwest of Klakknabben Peak, just north of the Kirwan Escarpment in Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and from additional air photos (1958–59), and named Gavlpiggen (the gable peak).

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.

Klakknabben Peak is a low isolated peak 2 nautical miles (4 km) northeast of Gavlpiggen Peak, just north of the Kirwan Escarpment in Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by Norwegian–British–Swedish Antarctic Expedition (1949–52) and from additional air photos (1958–59), and named Klakknabben.

Kirwan Escarpment

The Kirwan Escarpment is a prominent northwest-facing escarpment which lies south of the Penck Trough in Queen Maud Land, Antarctica. The escarpment is featured by moderate-height cliffs and prominent rock spurs interspersed with glaciers and steep ice slopes and trends northeast–southwest for about 90 nautical miles (170 km). At least the northern end of this feature was included in the aerial photography of the general area by the Third German Antarctic Expedition (1938–39), but the maps resulting from that expedition do not portray the escarpment properly. The escarpment was mapped by Norwegian cartographers from surveys and air photos (1958–59) and named for Laurence P. Kirwan, Director of the Royal Geographical Society.

Deep Freeze Range

The Deep Freeze Range is a rugged mountain range, over 128 km (80 mi) long and about 16 km (10 mi) wide, rising between Priestley and Campbell glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and mid portions of the range were observed by early British expeditions to the Ross Sea.

Hansen Mountains is a large group of nunataks rising to about 300 m (980 ft) above the Antarctic plateau. The mountains are approximately 89 km (55 mi) south of Stefansson Bay and they extend 40 km (25 mi) from northwest to southeast in Kemp Land, East Antarctica. The Hansen Mountains were first mapped by Norwegian cartographers from air photos taken by the 1936–1937 Lars Christensen Expedition. They were named for H.E. Hansen, the Norwegian cartographer who compiled the maps for this and other Norwegian Antarctic expeditions.

Bingham Peak is a sharp peak, 1,540 metres (5,050 ft) high, located 2.5 nautical miles (5 km) southeast of Springer Peak in the Heritage Range, Ellsworth Mountains. It was mapped by the United States Geological Survey from ground surveys and from U.S. Navy air photos, 1961–66, and named by the Advisory Committee on Antarctic Names for Joseph P. Bingham, an auroral scientist at Eights Station in 1965.

Urnosa Spur is a spur at the west side of Urfjelldokka Valley, in the southwest part of the Kirwan Escarpment in Queen Maud Land. Mapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–52) and additional air photos (1958–59). They gave the name Urnosa.

Ovbratten Peak is a steep, pyramidal rock peak about 2 nautical miles (3.7 km) southwest of Hogfonna Mountain, in the Borg Massif of Queen Maud Land. Mapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–52) and named Ovbratten.

The Juno Peaks are two steep-sided nunataks with a small rock to the west, forming part of an east-west ridge 6 nautical miles (11 km) southwest of Mimas Peak, lying near the head of Saturn Glacier in southern Alexander Island, Antarctica. They were mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. The nunataks were named by the UK Antarctic Place-Names Committee after Juno, one of the asteroids lying between the orbits of the planets Mars and Jupiter.

Kråsen Crevasse Field is a crevasse field about 15 nautical miles (30 km) long in the lower part of Jutulstraumen Glacier, in Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Kråsen.

Kubbestolen Peak is a bare rock peak, 2,070 metres (6,800 ft) high, at the northwest end of Vinten-Johansen Ridge in the Kurze Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Kubbestolen.

Gygra Peak is a rock peak, 1,980 metres (6,500 ft) high, just west of Risen Peak in the Gjelsvik Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Gygra.

Mount Schumacher is a mountain, 1,230 m, standing 6 nautical miles (11 km) southwest of Nils Jorgen Peaks on the west side of Ahlmann Ridge in Queen Maud Land. Mapped by Norwegian cartographers from surveys and air photos by Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–52) and air photos by the Norwegian expedition (1958–59).

The Holtedahl Peaks are a group of peaks and ridges lying northward of Steinskaret Gap and forming the northern portion of the Kurze Mountains, in Queen Maud Land, Antarctica. The name "Holtedahlfjella" was applied to the entire extent of the Kurze Mountains on a Norsk Polarinstitutt map of 1966, but the name Kurze has priority, having been given by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39. For the sake of historical continuity, Kurze Mountains has been retained as applied by Ritscher; the name Holtedahl Peaks is recommended for the elevations northward of Steinskaret Gap in these mountains. The name is for Professor Olaf Holtedahl, a noted Norwegian geologist who worked in the South Shetland Islands and the Palmer Archipelago area in 1927–28.

Mount Kane is a mountain standing 6 nautical miles (11 km) west-southwest of Squires Peak in the Playfair Mountains of southern Palmer Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–67, and was named by the Advisory Committee on Antarctic Names for Alan F. Kane, a construction mechanic with the South Pole Station winter party in 1964.
