Mikkelsen Bay is a bay, 27.8 kilometres (15 nmi) wide at its mouth and indenting 18.5 kilometres (10 nmi), entered between Bertrand Ice Piedmont and Cape Berteaux along the west coast of Graham Land, Antarctica. First seen from a distance in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, but not recognized as a large bay. First surveyed in 1936 by the BGLE under Rymill, and resurveyed by the Falkland Islands Dependencies Survey in 1948–49. The name was proposed by members of BGLE for Ejnar Mikkelsen, Danish Arctic explorer and Inspector for East Greenland, 1934–50.
Northeast Glacier is a steep, heavily crevassed glacier on the west side of Hemimont Plateau, 21 km (13 mi) long and 8 km (5 mi) wide at its mouth, which flows from McLeod Hill westward and then south-westwards into Marguerite Bay between the Debenham Islands and Roman Four Promontory, on the west coast of Graham Land, Antarctica. Northeast Glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill. It was resurveyed in 1940 by members of the United States Antarctic Service (USAS), who first used the glacier as a sledging route, and so named by them because it lay on the north-eastern side of their base at Stonington Island.
Red Rock Ridge or Morro Roca Roja or Promontorio Roca Roja is a conspicuous reddish-colored ridge or promontory which rises to 690 m and projects from the west coast of Graham Land between Neny Fjord and Rymill Bay. Red Rock Ridge is located at 68°18′S67°08′W and has an elevation of 690 m. Red Rock Ridge was surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, who so named it because of its color. Further surveys in 1948 by the Falkland Islands Dependencies Survey (FIDS) have identified this ridge as the feature first sighted in 1909 and named "Île Pavie" or "Cap Pavie" by the French Antarctic Expedition under Jean-Baptiste Charcot, but the name Red Rock Ridge is now too firmly established to alter. The name Pavie Ridge has been assigned to the prominent rocky ridge at 68°34′S66°59′W.
Martin Glacier is a glacier, 3 nautical miles (6 km) wide and 9 nautical miles (17 km) long, which flows west and then northwest from the south side of Mount Lupa to the southeast corner of Rymill Bay where it joins Bertrand Ice Piedmont, on the west coast of Graham Land, Antarctica. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, and was resurveyed in 1948–1949 by the Falkland Islands Dependencies Survey. The glacier was named for James Hamilton Martin, a member of the British Australian and New Zealand Antarctic Research Expedition (1929–1931) under Sir Douglas Mawson, and first mate of the Penola during the BGLE.
Bertrand Ice Piedmont is an ice piedmont about 20 kilometres (11 nmi) long and from 6 to 9 kilometres wide, lying between Rymill Bay and Mikkelsen Bay on the Fallières Coast of Graham Land.
Mount Wilcox is a mountain with a sharp, rocky, triangular peak surmounting the southeast corner of Square Bay, 13 kilometres (8 mi) east of Camp Point on the west coast of Graham Land, Antarctica. The mountain was apparently first seen and roughly charted in 1909 by the French Antarctic Expedition under Charcot. It was surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill and was photographed from the air in 1940 by the United States Antarctic Service (USAS). The name, proposed by Colonel Lawrence Martin, is for Phineas Wilcox, mate on the Hero, in which Captain Nathaniel Palmer explored the Antarctic mainland south of Deception Island in 1820.
Cape Berteaux is a cape surmounted by a high rock peak between Mikkelsen Bay and Wordie Ice Shelf on the west coast of Graham Land. The French Antarctic Expedition under Charcot, 1908–1910, originally applied the name Berteaux to an island in essentially this position. The British Graham Land Expedition (BGLE) under Rymill, 1934–1937, identified the feature sighted by Charcot as the cape described above. It is named by Charcot for a Monsieur Berteaux who helped obtain funds for his expedition.
The Batterbee Mountains are a group of prominent mountains rising to 2,200 metres (7,200 ft), which forms part of the dissected edge of Dyer Plateau overlooking George VI Sound, on the west coast of Palmer Land. First seen and photographed from the air by Lincoln Ellsworth on 23 November 1935, they were charted from the ground in October 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and named after Sir Harry Batterbee (1880–1976), Assistant Under-Secretary of State, Dominions Office, 1930–38, and Chairman of the Polar Committee in 1934, who gave help to the expedition.
Bertram Glacier is a glacier, 15 nautical miles (28 km) long and 18 nautical miles (33 km) wide at its mouth, which flows west from the Dyer Plateau of Palmer Land into George VI Sound between Wade Point and Gurney Point.
Neny Bay is a small indentation in the west coast of Graham Land which is bounded on the west by Neny Island, and on the northwest and southeast respectively by Stonington Island and Roman Four Promontory. The bay was first charted by the British Graham Land Expedition (BGLE) under Rymill, 1934–37. The name, derived from Neny Island, was suggested by members of East Base of the United States Antarctic Service (USAS), 1939–41, who referred to it as Neny Island Bay.
Stipple Rocks is a compact group of more than twenty rocks, lying 3 nautical miles (6 km) northwest of Millerand Island in Marguerite Bay, off the west coast of Graham Land. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill, and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). The name, applied by FIDS, is descriptive of the representation on a map of the numerous rocks in this group.
Pod Rocks is a small compact group of rocks, lying 9.3 kilometres (5 nmi) west of Millerand Island in Marguerite Bay, off the west coast of Graham Land. First roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. The rocks were visited and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS), who established a sealing camp there. The name, proposed by FIDS, derives from the old sealers' term "pod," meaning a group of seals hauled ashore.
The Tiber Rocks are a group of rocks lying near the head of Rymill Bay, close west of the mouth of Romulus Glacier and 6 kilometres (3 nmi) northwest of the highest summit of Black Thumb, off the west coast of Graham Land. First seen and roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill, it was resurveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because of the association of these rocks with nearby Romulus and Remus Glaciers.
Randall Rocks is a group of rocks situated 1 kilometre (0.5 nmi) off the southwest corner of Miller and Island and trending in a NW-SE direction for 2 kilometres (1 nmi), lying in Marguerite Bay off the west coast of Graham Land. The group was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. It was resurveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS) and named for Terence M. Randall, FIDS radio operator at Stonington Island, 1947–49.
The Reference Islands is a group of rocky islands 2 nautical miles (3.7 km) west-northwest of the west tip of Neny Island and 1.5 nautical miles (2.8 km) southeast of Millerand Island, lying in Marguerite Bay off the west coast of Graham Land. First roughly charted in 1936 by the British Graham Land Expedition (BGLE) under Rymill. The islands were surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1947, and so named by them because they served as a convenient reference point for survey work.
Refuge Islands is a small group of islands lying 1 nautical mile (1.9 km) from the ice cliffs at the southwest side of Red Rock Ridge, off the west coast of Graham Land. Discovered and named by the British Graham Land Expedition (BGLE) under Rymill, 1934–37, who used these islands as a depot for sledge journeys south from the southern base in the Debenham Islands.
Romulus Glacier is a glacier, 7 nautical miles (13 km) long and 2 nautical miles (3.7 km) wide, which flows from the north slopes of Mount Lupa westward to Rymill Bay between the Blackwall Mountains and Black Thumb, on the west coast of Graham Land. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS), who so named it for its association with Remus Glacier, whose head lies near the head of this glacier.
Clarke Glacier is a 2 miles (3.2 km)-wide, 20 miles (32 km)-long glacier, located on the west coast of Graham Land in Antarctica. It flows west, along the north side of Sickle Mountain and the Baudin Peaks, to Mikkelsen Bay.
The Ryder Bay Islands Important Bird Area is a 520 ha designated site on the south-east coast of Adelaide Island, Antarctica. It has been identified as an Important Bird Area (IBA) by BirdLife International because it supports significant numbers of breeding seabirds, notably south polar skuas. The site encompasses the Léonie Islands lying at the mouth of Ryder Bay, as well as Rothera Point, the eastern headland of the bay.
Broken Island is an island 4.6 kilometres long, lying 2.8 km north of Centre Island in the north part of Square Bay, off the west coast of Graham Land. Discovered and named by the British Graham Land Expedition (BGLE) under Rymill, 1934–37.
