Horn Bluff ( 68°21′S149°45′E / 68.350°S 149.750°E / -68.350; 149.750 Coordinates: 68°21′S149°45′E / 68.350°S 149.750°E / -68.350; 149.750 ) is a prominent rocky headland on the northern side of the coastal island at the western side of Deakin Bay, Antarctica. The feature rises to 325 metres (1,070 ft) and is marked by the columnar structure of the dolerite forming the upper part of it. It was discovered and mapped as part of the mainland by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who applied the name for W.A. Horn of Adelaide, a patron of the expedition. The headland was shown to be on an island by Australian National Antarctic Research Expeditions air photos taken in 1962. [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.

A headland is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape. Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliffs.

Deakin Bay is a wide, open bay on the coast between Horn Bluff and Cape Freshfield. The bay was roughly delineated by the Far Eastern Party of the Australasian Antarctic Expedition (1911–14) under Sir Douglas Mawson, who named it for Sir Alfred Deakin, Prime Minister of Australia in 1910.

Daspit Glacier is a glacier 6 nautical miles (11 km) long, flowing east-northeast along the south side of Mount Shelby to the head of Trail Inlet, on the east coast of Graham Land, Antarctica. It was discovered by members of the East Base of the United States Antarctic Service, 1939–41, and was originally named Fleming Glacier after Rev. W.L.S. Fleming. It was photographed from the air in 1947 by the Ronne Antarctic Research Expedition under Finn Ronne, and charted in 1948 by the Falkland Islands Dependencies Survey. It was renamed by Ronne for Captain Lawrence R. Daspit, U.S. Navy, who assisted in obtaining Navy support for the Ronne expedition, the original name being transferred to Fleming Glacier on the Rymill Coast.

Posadowsky Glacier (Antarctica)

Apollo Glacier glacier in Antarctica

Apollo Glacier is a glacier, 9 nautical miles (17 km) long, flowing northeast and joining the lower part of Aphrodite Glacier 2 nautical miles (4 km) from the east coast of the Antarctic Peninsula. The lower part of this glacier 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 roughly surveyed by the Falkland Islands Dependencies Survey in November 1960. It was named by the UK Antarctic Place-Names Committee after Apollo, the god of manly youth and beauty in Greek mythology.

It was photographed from the air by the Ronne Antarctic Research Expedition in November 1947, and was surveyed by the Falkland Islands Dependencies Survey in December 1958. The glacier was so named by the UK Antarctic Place-Names Committee because the glacier flows from north to south along the meridian.

It drains northeastward into the eastern part of the Gillett Ice Shelf. The glacier was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, because of an airdrop of extra comforts from an aircraft which carried the Governor-General of New Zealand over this area was like "manna from heaven".

The Hornblende Bluffs are prominent bluffs that rise to 1,050 metres (3,440 ft), located 2 nautical miles (4 km) southeast of Mount Ellery and near the head of Suvorov Glacier, in the Wilson Hills of Antarctica.
