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.
Mount Erebus is the second-highest volcano in Antarctica, the highest active volcano in Antarctica, and the southernmost active volcano on Earth. It is the sixth-highest ultra mountain on an island, and the second-highest in Antarctica. It has a summit elevation of 3,794 metres (12,448 ft). It is located in the Ross Dependency on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. The mountain was named by Captain James Clark Ross in 1841 for his ship, the Erebus.
Mount Terror is an extinct volcano about 3,230 metres (10,600 ft) high on Ross Island, Antarctica, about 20 nautical miles eastward of Mount Erebus. Mount Terror was named in 1841 by Sir James Clark Ross for his second ship, HMS Terror. The captain of Terror was Francis Crozier, a close friend of Ross for whom the nearby Cape Crozier is named.
Borchgrevink Glacier is a large glacier in the Victory Mountains, Victoria Land, Antarctica. It drains south between Malta Plateau and Daniell Peninsula, and thence projects into Glacier Strait, Ross Sea, as a floating glacier tongue.
Hut Point Peninsula is a long, narrow peninsula from 2 to 3 nautical miles wide and 15 nautical miles long, projecting south-west from the slopes of Mount Erebus on Ross Island, Antarctica. McMurdo Station (US) and Scott Base (NZ) are Antarctic research stations located on the Hut Point Peninsula.
Mount Bird is a 1,765 metres (5,791 ft) high shield volcano standing about 7 nautical miles south of Cape Bird, the northern extremity of Ross Island. It was mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, and apparently named by them after Cape Bird.
Convoy Range is a broad range in Antarctica. Much of the range has a nearly flat plateau-like summit. It extends south from the Fry Saddle and ends at Mackay Glacier. The range has steep cliffs on its east side, but it slopes gently into the Cambridge Glacier on the western side. It is a peneplain, with an early Paleozoic granitic basement covered in sedimentary and igneous rocks from the Permian–Triassic to the Jurassic.
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. This cape was the site of Shackleton's Hut, the expedition camp of the British Antarctic Expedition, 1907–09.
Cape Crozier is the most easterly point of Ross Island in Antarctica. It was discovered in 1841 during James Clark Ross's expedition of 1839 to 1843 with HMS Erebus and HMS Terror, and was named after Commander Francis Crozier, captain of HMS Terror, one of the two ships of Ross' expedition.
Liv Glacier is a steep valley glacier, 40 nautical miles long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and Duncan Mountains. It was discovered in 1911 by Roald Amundsen, who named it for the daughter of Fridtjof Nansen.
The Kyle Hills are a prominent group of volcanic cones, hills, ridges, and peaks that occupy the eastern part of Ross Island, Antarctica, between Mount Terror and Cape Crozier. The hills extend east–west for 8 nautical miles (15 km), rising from sea level at Cape Crozier to about 2,600 metres (8,500 ft) in Mount McIntosh at the western end of the group. Local relief of features is on the order of 200 metres (660 ft).
Wood Bay is a large bay which is bounded by Cape Johnson and Aviator Glacier Tongue on the north, and Cape Washington on the south, along the coast of Victoria Land, Antarctica. It was discovered in 1841 by Captain James Clark Ross, Royal Navy, and named by him for Lieutenant James F.L. Wood of the ship HMS Erebus.
Windless Bight is a prominent bight that indens the south side of Ross Island, Antarctica, eastward of Hut Point Peninsula. It was named by the Winter Journey Party, led by Wilson, of the British Antarctic Expedition, 1910–13, which encountered no wind in this area. The bight is permanently frozen. It is the site of a station that monitors infrasound to detect violations of the Comprehensive Nuclear-Test-Ban Treaty.
Wohlschlag Bay is a large bay indenting the western side of Ross Island, Antarctica, and lying between Harrison Bluff and Cape Royds.
The Denton Hills are a group of rugged foothills, 24 nautical miles long southwest–northeast and 9 nautical miles wide, to the east of the Royal Society Range on the Scott Coast, Victoria Land, Antarctica.
Mount Falconer is a mountain, 810 metres (2,660 ft) high, surmounting Lake Fryxell on the north wall of Taylor Valley, between Mount McLennan and Commonwealth Glacier in Antarctica. It was named by the Western Journey Party, led by Thomas Griffith Taylor, of the British Antarctic Expedition, 1910–13.
Saint Johns Range is a crescent-shaped mountain range about 20 nautical miles long, in Victoria Land, Antarctica. It is bounded on the north by the Cotton Glacier, Miller Glacier and Debenham Glacier, and on the south by Victoria Valley and the Victoria Upper Glacier and Victoria Lower Glacier.
The Horowitz Ridge is a rock ridge between David Valley and King Valley in the Asgard Range of Victoria Land, Antarctica.
Lewis Bay is a bay indenting the north coast of Ross Island, Antarctica, between Mount Bird and Cape Tennyson.
Blue Glacier is a large glacier which flows into Bowers Piedmont Glacier about 10 nautical miles south of New Harbour, in Victoria Land, Antarctica. It was discovered by the British National Antarctic Expedition (BrNAE) under Robert Falcon Scott, 1901–04, who gave it this name because of its clear blue ice at the time of discovery.
