The Territory of Heard Island and McDonald Islands is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall area is 372 km2 (144 sq mi) and it has 101.9 km (63 mi) of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947.
The Balleny Islands are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about 160 km (99 mi) in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot.
Ross Island is an island in Antarctica lying on the east side of McMurdo Sound and extending 43 nautical miles from Cape Bird on the north to Cape Armitage on the south, and a like distance from Cape Royds on the west to Cape Crozier on the east. The island is entirely volcanic. Mount Erebus, 3,795 metres (12,451 ft), near the center, is an active volcano. Mount Terror, 3,230 metres (10,600 ft), about 20 nautical miles eastward, is an extinct volcano. Mount Bird rises to 1,765 metres (5,791 ft) just south of Cape Bird. Ross Island lies within the boundary of Ross Dependency, an area of Antarctica claimed by New Zealand.
Peter I Island is an uninhabited volcanic island in the Bellingshausen Sea, 450 kilometres (240 nmi) from continental Antarctica. It is claimed as a dependency of Norway and, along with Bouvet Island and Queen Maud Land, composes one of the three Norwegian dependent territories in the Antarctic and Subantarctic. The island measures approximately 11 by 19 kilometres, with an area of 156 km2 (60 sq mi); its highest point is the ultra-prominent, 1,640-metre-tall (5,380 ft) Lars Christensen Peak. Nearly all the island is covered by a glacier, and it is surrounded most of the year by pack ice, making it inaccessible during these times. There is little vertebrate animal life on the island, apart from some seabirds and seals.
The Ross Ice Shelf is the largest ice shelf of Antarctica. It is several hundred metres thick. The nearly vertical ice front to the open sea is more than 600 kilometres (370 mi) long, and between 15 and 50 metres high above the water surface. Ninety percent of the floating ice, however, is below the water surface.
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica.
The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately 1,300 kilometres (810 mi) from the South Pole.

Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of 1,610,000 km2 (620,000 sq mi), it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century.
Terra Nova Bay is a bay which is often ice free, about 40 nautical miles long, lying between Cape Washington and the Drygalski Ice Tongue along the coast of Victoria Land, Antarctica. It was discovered by the British National Antarctic Expedition under Robert Falcon Scott, 1901–1904, and named by him after Terra Nova, one of the relief ships for the expedition.
King Edward VII Land or King Edward VII Peninsula is a large, ice-covered peninsula which forms the northwestern extremity of Marie Byrd Land in Antarctica. The peninsula projects into the Ross Sea between Sulzberger Bay and the northeast corner of the Ross Ice Shelf, and forms part of the Ross Dependency. Edward VII Peninsula is defined by the Ross Ice Shelf on the southwest, Okuma Bay on the west, and to the east by Sulzberger Bay and the Saunders Coast, all essentially on the Ross Sea / Southern Ocean in Antarctica. The northwest extremity of the peninsula is Cape Colbeck. Edward VII Peninsula is located at 77°40′S155°00′W.
Cape Colbeck is a prominent ice-covered cape which forms the northwestern extremity of the Edward VII Peninsula and Marie Byrd Land in Antarctica. It was discovered in January 1902 by the British National Antarctic Expedition and named for Captain William Colbeck, Royal Naval Reserve, who commanded Robert Scott's relief ship, the Morning.
The DiscoveryExpedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly.
Cape Royds is a dark rock cape forming the western extremity of Ross Island, facing on McMurdo Sound, Antarctica. It was discovered by the British National Antarctic Expedition (BrNAE) (1901–1904) and named for Lieutenant Charles Royds, Royal Navy, who acted as meteorologist on the expedition. Royds subsequently rose to become an Admiral and was later Commissioner of the Metropolitan Police, London. The cape is the site of Shackleton's Hut, the expedition camp of the British Antarctic Expedition, 1907–09.
Minna Bluff is a narrow, bold peninsula, 25 nautical miles long and 3 nautical miles wide, projecting southeast from Mount Discovery into the Ross Ice Shelf, Antarctica. It was discovered by the British National Antarctic Expedition (1901-04) which named it for Minna, the wife of Sir Clements Markham, the "father" of the expedition. It culminates in a south-pointing hook feature, and is the subject of research into Antarctic cryosphere history, funded by the National Science Foundation, Office of Polar Programs.
Farthest South refers to the most southerly latitude reached by explorers before the first successful expedition to the South Pole in 1911.
Haggits Pillar is a stack 203 feet (62 m) high in the South Pacific Ocean at the northwestern edge of the Ross Sea, lying 250 metres (270 yd) west of Scott Island and some 500 kilometres (310 mi) north-northeast of Cape Adare, Victoria Land, Antarctica. It measures 50 metres (55 yd) in diameter, yielding an area of less than 0.2 hectares.
The Southern CrossExpedition, otherwise known as the British Antarctic Expedition, 1898–1900, was the first British venture of the Heroic Age of Antarctic Exploration, and the forerunner of the more celebrated journeys of Robert Falcon Scott and Ernest Shackleton. The brainchild of the Anglo-Norwegian explorer Carsten Borchgrevink, it was the first expedition to over-winter on the Antarctic mainland, the first to visit the Great Ice Barrier—later known as the Ross Ice Shelf—since Sir James Clark Ross's groundbreaking expedition of 1839 to 1843, and the first to effect a landing on the Barrier's surface. It also pioneered the use of dogs and sledges in Antarctic travel.
William Colbeck was a British seaman who distinguished himself on two Antarctic expeditions.
Ash Point is a rounded low ice-free point forming the southeast side of the entrance to Discovery Bay in the northeast of Greenwich Island in the South Shetland Islands, Antarctica with an adjacent ice-free area of 201 hectares. Letelier Bank is lying off Ash Point, while Bascopé Point is situated 460 m (503 yd)to the southwest, with the 1 km (0.62 mi) wide Rojas Cove indenting for 310 m (339 yd) the coast between that point and Guesalaga Peninsula. The area was visited by early 19th century sealers.
