Canis Heights

Last updated

Canis Heights is a mainly snow-covered ridge located between the two upper tributaries of Millett Glacier on the western edge of the Dyer Plateau of Palmer Land. The feature was named by the UK Antarctic Place-Names Committee after the constellations of Canis Major and Canis Minor.

Millett Glacier is a heavily crevassed glacier in Antarctica, 13 nautical miles (24 km) long and 7 nautical miles (13 km) wide, flowing west from the Dyer Plateau of Palmer Land to George VI Sound, immediately north of Wade Point. In its lower reaches the north side of this glacier merges with Meiklejohn Glacier. Millett Glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and was named by the UK Antarctic Place-Names Committee in 1954 for Hugh M. Millett, chief engineer of the Penola during the BGLE.

Dyer Plateau

Dyer Plateau is a broad ice-covered upland of north-central Palmer Land, bounded to the north by Fleming Glacier and Bingham Glacier, and to the south by the Gutenko Mountains. It is buttressed by Goettel Escarpment.

Palmer Land geographic region

Palmer Land is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between US-ACAN and UK-APC, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.

Finsterwalder Glacier glacier in Antarctica

Finsterwalder Glacier is a glacier on the northwest side of Hemimont Plateau, 2 nautical miles wide and 10 nautical miles long, flowing southwest from the central plateau of Graham Land, Antarctica, toward the head of Lallemand Fjord. Its mouth lies between the mouths of Haefeli Glacier and Klebelsberg Glacier, the three glaciers merging with Sharp Glacier where the latter enters the fjord. It was first surveyed from the plateau in 1946–47 by the Falkland Islands Dependencies Survey, and named by them for Sebastian Finsterwalder and his son, Richard Finsterwalder, German glaciologists.

Balsam Beach is a narrow boulder beach with jagged islands close offshore, lying 0.75 nautical miles (1.4 km) east of Dartmouth Point in Cumberland East Bay, South Georgia. The beach appears on earlier charts, but the name was given by the Falkland Islands Dependencies Survey (FIDS) in 1951 following a sketch survey. The name is one of a group in the vicinity of Dartmouth Point derived from the chemical stains used in the preparation for histological examination of biological material collected there by FIDS.

Barber Glacier glacier in Antarctica

Barber Glacier is a glacier rising just east of Mount Bruce in the Bowers Mountains and flowing north to the coast between Stuhlinger Ice Piedmont and Rosenau Head, Victoria Land, Antarctica. The glacier was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–65, and named by the Advisory Committee on Antarctic Names for Captain Don W. Barber, CE, USA, construction and equipment officer, U.S. Naval Support Force, Antarctica, 1967 and 1968. The glacier lies on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Dickey Peak mountain in the Ellsworth Mountains, Antarctica

Dickey Peak is a rocky peak rising to 1504 m in the northwestern part of the Flowers Hills in the Sentinel Range of the Ellsworth Mountains in Antarctica. It overlooks Dater Glacier to the west and Lardeya Ice Piedmont to the east. The feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Clifford R. Dickey, Jr., an electronics technician at the South Pole Station in 1957.

Transition Glacier is a glacier extending along the east coast of Alexander Island, 8 nautical miles (15 km) long and 2 nautical miles (3.7 km) wide, which flows east into the George VI Ice Shelf that occupies George VI Sound along the north side of Block Mountain and Tilt Rock. The glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Surveyed in 1949 by the Falkland Islands Dependencies Survey, and so named by them because this glacier marks the transition between igneous rocks to the north and sedimentary rocks to the south.

The Ganymede Heights consist of rounded ridges with extensive rock outcrops rising to about 600 m (2,000 ft), between Jupiter Glacier and Ablation Valley on the eastern side of Alexander Island, Antarctica. They were mapped by the Directorate of Overseas Surveys from satellite imagery supplied by the US National Aeronautics and Space Administration in cooperation with the US Geological Survey. They were named by the UK Antarctic Place-Names Committee from association with Jupiter Glacier after Ganymede, one of the satellites of the planet Jupiter. The feature also lies close to the Galileo Cliffs, which were named for the moon's discoverer, Galileo Galilei (1564-1642). The site lies within Antarctic Specially Protected Area (ASPA) No.147.

Klebelsberg Glacier glacier in Antarctica

Klebelsberg Glacier is a glacier, 7 nautical miles (13 km) long and 2 nautical miles (4 km) wide, situated at the south side of Finsterwalder Glacier and flowing from Hemimont Plateau northwestward between Armula Peak and Smilyan Bastion on Graham Land, Antarctica, toward the head of Lallemand Fjord. With Finsterwalder Glacier and Haefeli Glacier, its mouth merges with Sharp Glacier where the latter enters the fjord. It was first surveyed from the plateau in 1946–47 by the Falkland Islands Dependencies Survey, and named by them for Raimund von Klebelsberg, an Austrian glaciologist.

Sirius Cliffs is a conspicuous isolated nunatak with steep rock cliffs all along its north face, located between Mount Lepus and Procyon Peaks on the south side of Millett Glacier, in Palmer Land, Antarctica.

Snowshoe Glacier is a glacier 8 nautical miles (15 km) long flowing west from a col in the southwest flank of Neny Glacier into Neny Fjord, western Graham Land. Roughly surveyed from the ground (1936) and photographed from the air (1937) by British Graham Land Expedition (BGLE). Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1949. The name was suggested by K.S.P. Butler of the FIDS in 1948 because the shape of the glacier with its narrow head and wide mouth resembles a snowshoe.

LaVergne Glacier is a tributary glacier about 7 nautical miles (13 km) long, flowing east along the southern slopes of the Seabee Heights of Antarctica to enter Liv Glacier close southwest of McKinley Nunatak.

Mount Leckie is a roughly circular outcrop about 3 nautical miles (6 km) east of Martin Massif in the Porthos Range, Prince Charles Mountains, Antarctica. It was visited by the Australian National Antarctic Research Expeditions southern party (1956–57), and was named for Squadron Leader D.W. Leckie, Royal Australian Air Force, who commanded the RAAF Antarctic Flight at Mawson Station, 1956.

Sh2-308

Sh2-308, also designated as Sharpless 308, RCW 11, or LBN 1052, is an emission nebula and HII region located near the center of the constellation Canis Major, composed of ionised hydrogen. It is about 8 degrees south of Sirius, the brightest star in the night sky. The nebula is bubble-like, surrounding a Wolf-Rayet star named EZ Canis Majoris. This star is in the brief, pre-supernova phase of its stellar evolution. The nebula is about 4,530 light-years (1,389 pc) away from Earth, but some sources indicate that both the star and the nebula are up to 5,870 light-years (1,800 pc) away. Yet others indicate the nebula is as close as 1,875 light-years (575 pc) from Earth.

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.
