The Capella Rocks ( 70°39′S66°32′W / 70.650°S 66.533°W / -70.650; -66.533 Coordinates: 70°39′S66°32′W / 70.650°S 66.533°W / -70.650; -66.533 ) form a low, rocky ridge composed of several nunataks, located near the head of Bertram Glacier, 2 nautical miles (4 km) northeast of the Auriga Nunataks, in Palmer Land. They were named by the UK Antarctic Place-Names Committee after the star Capella in the constellation of Auriga. [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.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Bertram Glacier is a glacier, 15 nautical miles (28 km) long and 18 nautical miles (33 km) wide at its mouth, which flows west from the Dyer Plateau of Palmer Land into George VI Sound between Wade Point and Gurney Point.

Neptune Range

The Neptune Range is a mountain range, 112 km (70 mi) long, lying WSW of Forrestal Range in the central part of the Pensacola Mountains in Antarctica. The range is composed of Washington Escarpment with its associated ridges, valleys and peaks, the Iroquois Plateau, and the Schmidt and Williams Hills. It was discovered and photographed on January 13, 1956 on a US Navy transcontinental plane flight from McMurdo Sound to Weddell Sea and return.

Prince Charles Mountains mountain range

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Auriga Nunataks

The Auriga Nunataks are a small group of nunataks in Palmer Land, Antarctica, located 21 miles (34 km) east of Wade Point at the head of Bertram Glacier. The highest of these rises to a sharp peak and is visible for a great distance. They were named by the UK Antarctic Place-Names Committee after the constellation of Auriga.

The Alexander Nunataks are two coastal nunataks at the southern limit of the Windmill Islands, standing on the shore of Penney Bay 0.4 nautical miles (0.7 km) east of the base of the Browning Peninsula. They were first mapped from air photos taken by U.S. Navy Operation Highjump and Operation Windmill in 1947 and 1948, and named by the Advisory Committee on Antarctic Names for Photographer's Mate H.N. Alexander, a member of one of the two Operation Windmill photographic units that obtained air and ground photos of the area in January 1948.

Aphrodite Glacier glacier in Antarctica

Aphrodite Glacier is a glacier 15 nautical miles (28 km) long flowing north to the east coast of the Antarctic Peninsula 3 nautical miles (6 km) west of Victory Nunatak. The lower portion of the feature was first plotted by W.L.G. Joerg from aerial photographs taken by Sir Hubert Wilkins in December 1928 and by Lincoln Ellsworth in November 1935. The glacier was subsequently photographed by the Ronne Antarctic Research Expedition in December 1947 and surveyed by the Falkland Islands Dependencies Survey in December 1958 and November 1960. It was named by the UK Antarctic Place-Names Committee after Aphrodite, the goddess of love in Greek mythology.

Butcher Nunatak is a nunatak at the south end of the Birchall Peaks, 4 nautical miles (7 km) southwest of Swarm Peak, in the Ford Ranges of Marie Byrd Land. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos (1959–65), and named by the Advisory Committee on Antarctic Names for Robert S. Butcher, builder, U.S. Navy, at Byrd Station in 1967.

The Church Nunataks are a line of small nunataks 1 nautical mile (2 km) northeast of Mount Smethurst and 28 nautical miles (52 km) southwest of the Stor Hanakken Mountain in Enderby Land. They were plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1957, and named by the Antarctic Names Committee of Australia for S.W. Church, radio officer at Wilkes Station in 1961.

Coal Nunatak is a flat-topped rock mass with steep cliffs facing south, standing 2 nautical miles (4 km) southwest of Corner Cliffs on the southeast coast of Alexander Island, Antarctica. It was first seen from the air by Lincoln Ellsworth on November 23, 1935, and mapped from photos obtained on that flight by W.L.G. Joerg. Observed from the northwest, only the summit protrudes above the coastal ice, and it was uncertain whether this was a peak on Alexander Island or an island in George VI Sound. Its true nature was determined by the Falkland Islands Dependencies Survey (FIDS) who visited and surveyed this nunatak in 1949. So named by FIDS because thin lenses of coal occur there.

Natani Nunatak is a nunatak 1.5 nautical miles (2.8 km) north-northeast of the extremity of Snake Ridge in the Patuxent Range, Pensacola Mountains. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1956-66. Named by Advisory Committee on Antarctic Names (US-ACAN) for Kirmach Natani, biologist at South Pole Station, winter 1967.

It was visited in 1977–78 by a United States Antarctic Research Program – Arizona State University geological party, led by Edmund Stump, and named in the spirit of Coalsack Bluff, as thin lenses of disintegrating mica and schist form a type of light soil on the slopes of the nunatak.

Higgins, U.S. Navy, a member of the McMurdo Station party during Operation Deep Freeze 1966.

Henkle Peak is a peak about 15 nautical miles (30 km) north of Mount Rex in Palmer Land, Antarctica. It lies among a group of nunataks that were first sighted and photographed by Lincoln Ellsworth on November 23, 1935. The peak was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1961–66, and was named by the Advisory Committee on Antarctic Names for Charles R. Henkle of USGS, a topographic engineer with the Marie Byrd Land Survey Party, 1967–68.

Kelley Nunatak is a nunatak on the north side of Leverett Glacier in Antarctica, 12 nautical miles (22 km) northeast of Mount Gould. It was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Herbert O. Kelley, a radioman with the Byrd Station winter party in 1958.

Recluse Nunatak is an isolated rock exposure lying on the Handel Ice Piedmont, midway between Haydn Inlet and the Colbert Mountains in the west-central portion of Alexander Island, Antarctica. The nunatak was 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. The name given by the United Kingdom Antarctic Place-Names Committee (UK-APC) suggests the isolated position of the nunatak, considering this landform is situated far away from other landforms of Alexander Island.
