Lavett Bluff ( 53°11′S73°32′E / 53.183°S 73.533°E / -53.183; 73.533 Coordinates: 53°11′S73°32′E / 53.183°S 73.533°E / -53.183; 73.533 ) is a rock bluff between Deacock Glacier and Fiftyone Glacier on the south side of Heard Island in the southern Indian Ocean. It was surveyed in 1948 by an Australian National Antarctic Research Expedition (ANARE) and named "Cape Lavett" for Lieutenant John L. Lavett, Royal Australian Navy, one of the officers on HMAS Labuan, the relief ship for the expedition. Further ANARE exploration led to revision of the name in 1964 to Lavett Bluff. [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.

Cliff A vertical, or near vertical, rock face of substantial height

In geography and geology, a cliff is a vertical, or nearly vertical, rock exposure. Cliffs are formed as erosion landforms by the processes of weathering and erosion. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually formed by rock that is resistant to weathering and erosion. Sedimentary rocks most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.

Deacock Glacier glacier in Antarctica

Deacock Glacier is a glacier close west of Lavett Bluff on the south side of Heard Island in the southern Indian Ocean. Its terminus is between Cape Labuan and Long Beach. To the east of Deacock Glacier is Fiftyone Glacier, whose terminus is located between Lavett Bluff and Lambeth Bluff. To the west of Deacock Glacier is Gotley Glacier, whose terminus is located between Cape Arkona and Cape Labuan.

Jacka Glacier glacier in Antarctica

Jacka Glacier is a 0.8-mile (1.3 km) long glacier which flows northeast from Hayter Peak and terminates in icefalls opposite Vanhoffen Bluff on the north side of Heard Island in the southern Indian Ocean. The glacier appears to be roughly charted on an 1860 sketch map compiled by Captain H.C. Chester, an American sealer operating in the area during this period. It was surveyed in 1948 by the Australian National Antarctic Research Expeditions, and named by them for Fred J. Jacka, an expedition physicist.

Abbotsmith Glacier glacier in Antarctica

Abbotsmith Glacier is a well-defined glacier, 3 miles (5 km) long, descending from the ice-covered west slopes of Big Ben to the west side of Heard Island in the southern Indian Ocean. The glacier lies between Walsh and Henderson Bluffs. Surveyed in 1948 by the ANARE who named it for John Abbotsmith, engineer with the party.

Kirkby Glacier is a glacier, 20 miles (30 km) in length. This glacier drains the central Anare Mountains of Antarctica and flows northwest to the sea 3 miles (5 km) from Cape North, and just north of Arthurson Bluff, northern Victoria Land.

Budd Pass is a mountain pass in the ridge that extends southwest from Budd Peak on Heard Island. The pass is 1 nautical mile (2 km) southwest of Budd Peak. It was surveyed by Australian National Antarctic Research Expeditions (ANARE), 1948–63, and named by the Antarctic Names Committee of Australia for G.M. Budd, ANARE officer-in-charge on Heard Island in 1954 and leader of the 1963 ANARE Heard Island expedition.

Budd Peak is a peak, 2,315 metres (7,600 ft) high, 1.7 nautical miles (3.1 km) southeast of Mawson Peak on Heard Island. The peak was mapped by Australian National Antarctic Research Expeditions (ANARE) in 1948, and named by the Antarctic Names Committee of Australia for G.M. Budd, ANARE officer-in-charge on Heard Island in 1954, and leader of the 1963 ANARE Heard Island expedition.

Campbell Peak is a peak, 2,415 metres (7,920 ft) high, standing 1.2 nautical miles (2.2 km) northeast of Mawson Peak, the summit of Heard Island. It was surveyed in 1948 by the Australian National Antarctic Research Expeditions (ANARE), who named it for Group-Captain Stuart A. Campbell, Royal Australian Air Force. Campbell visited Heard Island in 1929 as aircraft pilot with the British Australian New Zealand Antarctic Research Expedition led by Douglas Mawson, and again as leader of ANARE when a research station was established on the island in December 1947.

Walsh Bluff is a rock bluff close north of the mouth of Abbotsmith Glacier on the west side of Heard Island. Surveyed by ANARE in 1948. Named by Antarctic Names Committee of Australia (ANCA) for J.E. Walsh, ANARE weather observer on Heard Island in 1950 and 1954; dog attendant at Heard Island in 1951.

Melbourne Bluff is a rocky bluff, 385 metres (1,260 ft) high, standing 1.3 nautical miles (2.4 km) south of Cape Bidlingmaier and protruding above the ice-covered slopes at the north side of Heard Island. The feature was surveyed in 1948 by the Australian National Antarctic Research Expeditions and so named by them because it trends roughly east-northeast in the general direction of Melbourne, Australia, the home headquarters of the expedition.

South Barrier is a rocky ridge descending southward from Budd Peak along the east margin of Fiftyone Glacier and terminating at Lambeth Bluff in southern Heard Island. The descriptive name was applied by ANARE in 1948.

Vanhoffen Bluff is a rocky bluff immediately east of Jacka Glacier on the north coast of Heard Island. It is named for Ernst Vanhöffen (1858–1918), a German zoologist, and a member of the Gauss expedition under the leadership of Erich von Drygalski (1865–1949). During its 1902 investigations of the area, Drygalski applied the name Kap Vanhoffen to a cliffed feature about 1.5 nautical miles (2.8 km) to the northwest, near The Sentinel. The ANARE, during its 1948 survey of the island, transferred the Vanhoffen name to this bluff, reporting that no well-marked cape exists along the high cliffs to the northwest.

Cape Labuan is a rocky point midway between Cape Arkona and Lavett Bluff, forming the southwest extremity of Heard Island. It was charted in 1948 by the Australian National Antarctic Research Expeditions and named after HMAS Labuan, a relief ship for the expedition.

Lambeth Bluff is a rock coastal bluff at the east side of Fiftyone Glacier, on the south side of Heard Island. It was surveyed in 1948 by the Australian National Antarctic Research Expeditions (ANARE) and named "Cape Lambeth" for A. James Lambeth, a geologist with the expedition. Further ANARE exploration led to revision of the name in 1964 to Lambeth Bluff.
