Blackrock Head ( 67°15′S58°59′E / 67.250°S 58.983°E / -67.250; 58.983 Coordinates: 67°15′S58°59′E / 67.250°S 58.983°E / -67.250; 58.983 ) is a conspicuous coastal rock outcrop on the eastern part of Law Promontory, 3 nautical miles (6 km) northwest of Tryne Point. It was discovered in February 1936 by Discovery Investigations personnel on the William Scoresby and so named by them for its black, rocky appearance. [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.

Law Promontory in Antarctica was named after Phillip Law, who flew over and photographed this feature in February 1954.

Tryne Point is a rocky point at the east extremity of Law Promontory in Antartica, forming the west side of the entrance of Stefansson Bay. Charted by Norwegian cartographers from aerial photographs taken by the Norwegian expedition under Christensen in January–February 1937, and named Trynet, a Norwegian word meaning "the snout." The form Tryne, dropping the definite article, is approved with the added generic term point.

Kemp Coast

Kemp Coast is that portion of the coast of Antarctica that lies between the head of Edward VIII Bay, at 56°25′E, and William Scoresby Bay, at 59°34′E. It is named for a British sealing captain, Peter Kemp, who discovered land in this vicinity in 1833.

Mountaineer Range

Mountaineer Range is the range of mountains lying between the Mariner and Aviator Glaciers in Victoria Land, Antarctica. The seaward parts of the range were first viewed by Ross in 1841, and subsequently by several British and later American expeditions. The precise mapping of its overall features was accomplished from U.S. Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, in keeping with the backgrounds of members of the 1957–58 and 1958–59 field parties who made a reconnaissance of the area, and also in association with the names "Aviator" and "Mariner".

Brooks Nunatak is an isolated nunatak, 1,615 metres (5,300 ft) high, standing 6 nautical miles (11 km) southwest of Shurley Ridge on the south side of Mackin Table in the Patuxent Range, Pensacola Mountains. It was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1956–66, and named by the Advisory Committee on Antarctic Names for Robert E. Brooks, a biologist at South Pole Station, summer 1966–67.

Emerald Nunatak is a nunatak 1,250 metres (4,100 ft) high on the west side of the Douglas Range near the head of Hampton Glacier in northeast Alexander Island, Antarctica. It was so named by the UK Antarctic Place-Names Committee following surveys by the British Antarctic Survey, 1973–77, because of the greenish rock of which the feature is composed.

Felton Head is a flat-topped, dark brown headland with a sheer seaward side, standing 3.5 nautical miles (6 km) east of Harrop Island on the coast of Enderby Land, Antarctica. It was plotted from air photos taken by the Australian National Antarctic Research Expeditions in 1956, and was named for Sergeant Kevin Felton, Royal Australian Air Force, an engine fitter at Mawson Station in 1960.

Mount Fonda is a mountain, 695 metres (2,280 ft) high, in the northwest part of the Swanson Mountains, 6 nautical miles (11 km) south of Greegor Peak, in the Ford Ranges of Marie Byrd Land, Antarctica. It was mapped by the United States Antarctic Service (1939–41) under Rear Admiral Richard E. Byrd, and was named for Howard B. Fonda who contributed medical supplies to the Byrd Antarctic Expeditions of 1928–30 and 1933–35.

The Forgotten Hills are a small group of hills 6 nautical miles (11 km) southeast of the Intention Nunataks, at the west side of the head of Astronaut Glacier in Victoria Land, Antarctica. They were named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition, 1966–67, because none of the three parties that had visited the area had time to examine these hills. These hills lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Mount Gran is a large flat-topped mountain, 2,235 metres (7,330 ft) high, standing at the north side of Mackay Glacier and immediately west of Gran Glacier in Victoria Land, Antarctica. It was discovered by the British Antarctic Expedition, 1910–13, which named it for Tryggve Gran, a Norwegian naval officer who was a ski expert with the expedition.

Mount Metcalfe is a mountain at the south side of the head of McMorrin Glacier, 1.5 nautical miles (3 km) south of Mount Wilcox, in Graham Land, Antarctica. It was named by the UK Antarctic Place-Names Committee for Robert J. Metcalfe, a British Antarctic Survey surveyor at Stonington Island, 1960–62, who surveyed the area in 1962.

Mount Hancox is a prominent mountain, 3,245 metres (10,650 ft) high, about 6 nautical miles (11 km) southeast of Mount Burton, rising above the north margin of Malta Plateau in the Victory Mountains of Victoria Land, Antarctica. It was named by the Mariner Glacier geology party of the New Zealand Geological Survey Antarctic Expedition, 1966–67, for G.T. Hancox, senior geologist with the party in this area.

Lister Glacier is a glacier on the east side of the Royal Society Range in Antarctica, draining northeast from a large cirque immediately north of Mount Lister. It derives its name from Mount Lister, and was surveyed in 1957 by the New Zealand Blue Glacier Party of the Commonwealth Trans-Antarctic Expedition, 1956–58.

McMorrin Glacier is a glacier flowing west from Mount Metcalfe to Marguerite Bay in Graham Land, Antarctica. it was named by the UK Antarctic Place-Names Committee for Ian McMorrin, a British Antarctic Survey general assistant at Stonington Island, 1961–63, who helped survey this area in 1962.

Hermes Glacier is a glacier 8 nautical miles (15 km) long, flowing west into Weyerhaeuser Glacier in southern Graham Land, Antarctica. It was surveyed in January 1960 by the Falkland Islands Dependencies Survey who discovered the glacier after several fruitless attempts to find a route out of the mountains east of Earnshaw Glacier. It provided an ideal "road" back to known country and was therefore named after Hermes, the god of roads in Greek mythology. This name by the UK Antarctic Place-Names Committee initiated the idea of naming other features in this area after Greek gods.

Macey Cone is a small hill, 125 metres (410 ft) high, which marks the remnants of an extinct volcanic cone surmounting the lava cliffs at the northwest end of Laurens Peninsula, about 0.6 nautical miles (1.1 km) northeast of Cape Laurens, at the northwest end of Heard Island. The feature was surveyed in 1948 by the Australian National Antarctic Research Expeditions, who named it for L.E. Macey, a senior radio operator with the expedition.

Mount Thorarinsson is a peak at the south side of the terminus of Hess Glacier on the east coast of Graham Land. The feature forms a point on the rocky spur that descends from the plateau, and is one of the most distinctive features along the coast as viewed from the Larsen Ice Shelf. This coastal area was photographed by several American expeditions: United States Antarctic Service (USAS), 1939–41; Ronne Antarctic Research Expedition (RARE), 1947–48; U.S. Navy photos, 1968. Mapped by Falkland Islands Dependencies Survey (FIDS), 1947–48. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Sigurdur Thorarinsson, Icelandic glaciologist.

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.

Kane, a construction mechanic with the South Pole Station winter party in 1964.

Rip Point

Rip Point is a point on Nelson Island forming the south side of the east entrance to Fildes Strait, in the South Shetland Islands. The name appears on a British Admiralty chart showing the results of a survey by DI personnel on the Discovery II in 1935.

Cape Laurens is a cape which marks the northwestern extremity of Laurens Peninsula and Heard Island. The name was probably applied by Captain Franklin F. Smith, of the American bark Laurens, who visited Heard Island in 1855–56 and who, with Captain Erasmus Darwin Rogers, initiated sealing operations and longtime American sealer occupation of Heard Island. The name appears on a chart by the British expedition under George Nares, which visited the island in HMS Challenger in 1874 and utilized the names then in use by the sealers.

Cape Freeman is a cape marking the east end of the peninsula separating Seligman Inlet and Trail Inlet, on the east coast of Graham Land, Antarctica.
