Black Island (), in the Ross Archipelago, is immediately west of White Island. It was first named by the Discovery Expedition (1901–04) because of its lack of snow. The island's northernmost point is named Cape Hodgson, commemorating Thomas Vere Hodgson, one of the oldest members of the Discovery Expedition.
The highest point is Mount Aurora, a principal radio relay point.Mt. Aurora was named between 1958-1959 for the Aurora, one of the ships on Shackleton's Expedition. On the minor peak of Mount Melania is the principal earth-based ground-station for the US Antarctic Program.
Black Island is volcanic in origin, consisting of a series of trachytic lava domes and basaltic pyroclastic cones. to 3.8 million years. There are three main geological formations representing three eruptive sequences on Black Island: Nubian Basalt Formation, Aurora Trachyte Formation, and Melania Basalt Formation. The lack of snow is not due to volcanic activity but rather the fact that it is protected from wind by nearby Minna Bluff.Potassium–argon dating of Black Island volcanic rocks has given ages ranging from 1.69
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14 million km2.
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand.
Sturge Island is one of the three main islands in the uninhabited Balleny Islands group located in the Southern Ocean. It lies 25 km (16 mi) southeast of Buckle Island and 95 km (59 mi) north-east of Belousov Point on the Antarctic mainland. The island, in Oates Land, also forms part of the Ross Dependency, claimed by New Zealand.
Deception Island is an island in the South Shetland Islands close to the Antarctic Peninsula with a large and safe natural harbor. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling stationwith over 15,000 visitors per year. Two research stations are operated by Argentina and Spain during the summer season. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System.
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second largest uninhabited island in the world, after Devon Island.
Vega Island is a small island to the northwest of James Ross Island, on the Antarctic Peninsula. It is separated from James Ross Island by Herbert Sound. The island was named by Otto Nordenskjold, leader of the Swedish Antarctic Expedition (1901-04) in honour of the ship making the first voyage through the Northeast Passage, 1878-79.
Bridgeman Island or Bridgemans's Island or Bridgman Island or Helena Island is one of the South Shetland Islands. It is an almost circular, volcanic island marked by steep sides, 0.8 kilometres (0.5 mi) long and 240 m (787 ft) high, lying 37 kilometres (23 mi) east of King George Island. Bridgeman Island is located atand has an elevation of 240 m (787 ft). Bridgeman Island is an established name dating back to about 1820. Bridgeman Island is the remnants of a much larger volcanic edifice that is now largely submerged. The eroded volcano does not display youthful volcanic features. Several reports of 19th-century fumarolic activity may instead refer to the much younger Penguin Island.
Clarence Island is the easternmost island in the South Shetland Islands, off the coast of Antarctica. It is claimed by Argentina as part of Argentine Antarctica, by Britain as part of the British Antarctic Territory, and by Chile as part of the Chilean Antarctic Territory. The name dates back to at least 1820 and is now established in international usage, except for Russia, where it has been known as Shishkova Island since its discovery by Russians in 1821.
Penguin Island is one of the smaller of the South Shetland Islands of Antarctica.
Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island 61 km long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache after the province of Antwerp in Belgium. It lies south-west of Brabant Island at the south-western end of the group. The south-western coastline of the island forms part of the Southwest Anvers Island and Palmer Basin Antarctic Specially Managed Area. Cormorant Island, an Important Bird Area, lies 1 km off the south coast.
Brabant Island is the second largest island of the Palmer Archipelago within the British Antarctic Territory, lying between Anvers Island and Liège Island. Brabant Island is 59 km (37 mi) long north-south, 30 km (19 mi) wide, and rises to 2,520 m (8,268 ft) in Mount Parry. The interior of the island is occupied by two mountain ranges, Solvay Mountains in its southern part and Stribog Mountains in its central and northern parts.
Cockburn Island is an oval island 2.7 kilometres (1.7 mi) long, consisting of a high plateau with steep slopes surmounted on the northwest side by a pyramidal peak 450 m (1,476 ft) high, lying in the north-east entrance to Admiralty Sound, south of the north-east end of the Antarctic Peninsula. It was discovered by a British expedition (1839-43) led by Captain James Clark Ross, who named it for Admiral Sir George Cockburn, then serving as First Naval Lord.
Sewing-Machine Needles, also known as Rocas Ministro Ezcurra is a group of three prominent rock needles, the highest 45 m above water, lying close southeast of Rancho Point, Deception Island, in the South Shetland Islands. The name Sewing-Machine Rock was given by whalers for what was originally a conspicuous natural arch. Needles is now considered the more suitable descriptive term; an earthquake tremor in 1924 caused the arch to collapse. The name Rocas Ministro Ezcurra was given by Dr Douglas Mawson, leader of the Australasian Antarctic Expedition of 1912-14.
Mount Nubian is a sharp point of rock at the end of a ridge formed by a lava flow, situated 1 nautical mile (1.9 km) southeast of Mount Aurora on Black Island, in the Ross Archipelago. The rock forming the mountain is a glossy basalt and appears exceptionally black. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1958–59) after a tribe resident in Sudan, and in keeping with Black Island.
Mount Vision is a peak in the volcanic complex 1 nautical mile (1.9 km) northwest of Mount Aurora on Black Island. So named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1958–59) because of the magnificent view obtained of the peaks in this vicinity and of the Ross Archipelago and Minna Bluff area.
Melania Ridge is a basalt ridge running southeast for 3 nautical miles (6 km) from Mount Melania, on Black Island in the Ross Archipelago, Antarctica. It was named by the Advisory Committee on Antarctic Names (1999) in association with Mount Melania.
Mount Melania is a prominent rounded hill, 330 metres (1,080 ft) high, at the north end of Black Island, in the Ross Archipelago, Antarctica. It was first climbed by Hartley T. Ferrar and Louis Bernacchi of the British National Antarctic Expedition, 1901–04. The name, from a Greek word connoting the color black, an appropriate name for a feature on Black Island, was given by the New Zealand Geological Survey Antarctic Expedition in 1958–59.
Opalchenie Peak is the peak rising to 4,503.5 metres (14,775 ft) at the south extremity of the ice-covered Vinson Plateau, Sentinel Range in the Ellsworth Mountains, Antarctica. It is of low topographic prominence, just 63 metres (207 ft), with parent summit Fukushima Peak. The feature has a partly ice-free summit and south slopes, where two parallel ridges descend steeply southwestwards with Donnellan Glacier flowing in between and Mount Slaughter rising on the more southerly ridge. The northerly ridge was climbed up to the summit plateau by American Robert Anderson in November 1992, and subsequently used to establish a new route to Mount Vinson in 2003. Opalchenie Peak overlooks Vinson Plateau on the north, Craddock Massif on the southeast and upper Nimitz Glacier area on the southwest.
Kozhuh Peak is the ice-covered peak rising to 1711 m on the west side of Elgar Uplands, northern Alexander Island in Antarctica. It surmounts Delius Glacier to the north and Bartók Glacier to the south-southwest.
The McMurdo Volcanic Group is a large group of Cenozoic volcanic rocks in the western Ross Sea and central Transantarctic Mountains areas of Antarctica. It is one of the largest provinces of alkaline volcanism in the world, having formed as a result of continental rifting along the West Antarctic Rift System.
