Petty Rocks is a group of small rocks lying 5.6 kilometres (3 nmi) southeast of Cape Saenz in the center of the west part of Bigourdan Fjord, off the west coast of Graham Land. First roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named Petty Rock because of its small size. Air photos have disclosed that there are several rocks instead of just one.

Cape Saenz is a cape between Laubeuf and Bigourdan Fjords, forming the south extremity of Arrowsmith Peninsula on the west coast of Graham Land. Discovered by the French Antarctic Expedition under Charcot, 1908–10, and named by him for Dr. Roque Sáenz Peña, President of the Argentine Republic, 1910-13.

Bigourdan Fjord is a sound, 12 miles (19 km) long in an east-west direction and averaging 2 miles (3 km) wide, lying between Pourquoi Pas Island and the southwest part of Arrowsmith Peninsula, along the west coast of Graham Land. It was discovered by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for Guillaume Bigourdan, a noted French astronomer. It was roughly surveyed by the British Graham Land Expedition, 1934–37, under John Riddoch Rymill, and resurveyed by the Falkland Islands Dependencies Survey, 1948–50.

Graham Land geographical object

Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south.

Ambrose Rocks

The Ambrose Rocks are a small cluster of rocks situated southwest of the southern Argentine Islands and 1 nautical mile (2 km) northwest of the Gaunt Rocks, off the west coast of Graham Land, Antarctica. They were named by the UK Antarctic Place-Names Committee for David A. Ambrose, a survey assistant of the Hydrographic Survey Unit from HMS Endurance working in this area in February 1969.

Boutan Rocks are a small group of rocks lying 1.5 miles (2.4 km) southwest of Bruce Island, off the west coast of Graham Land. The rocks appear on an Argentine government chart of 1954. They were named by the UK Antarctic Place-Names Committee in 1960 for Louis Marie-Auguste Boutan (1859–1934), French naturalist and pioneer of submarine photography, 1893–98.

The Capstan Rocks are a small group of rocks, sometimes awash at high water and in strong winds, lying 1 nautical mile (2 km) south of Bob Island in the south entrance to Gerlache Strait, off the west coast of Graham Land. They were shown on an Argentine government chart of 1950, but not named. They were surveyed by the British Naval Hydrographic Survey Unit, 1956–57, and given this descriptive name by the UK Antarctic Place-Names Committee, because of a supposed resemblance to a capstan.

Centurion Glacier glacier in Antarctica

Centurion Glacier is a small steep glacier flowing northwest to Neny Bay between Mount Nemesis and Roman Four Promontory, on the west coast of Graham Land.

The Niblets

The Niblets is a group of rocks in the South Pacific. Situated between Harp Island and Beer Island, lying 15 kilometres (8 nmi) west of Prospect Point, off the west coast of Graham Land. Charted and named by the British Graham Land Expedition (BGLE), 1934–37, under Rymill. The name suggests the small size of features in the group.

Covey Rocks

Covey Rocks are a small group of rocks in Laubeuf Fjord, lying midway between Pinero Island and Cape Saenz, off the west coast of Graham Land. They were first roughly surveyed in 1936 by the British Graham Land Expedition under John Rymill. They were resurveyed in 1948 by the Falkland Islands Dependencies Survey, who gave the name because of the resemblance of these rocks to a covey of partridges sitting in a field.

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.

The Fringe Rocks are a group of rocks forming the western limit of the Saffery Islands, off the west coast of Graham Land, Antarctica. They were charted by the British Graham Land Expedition under John Rymill, 1934–37, and were so named by the UK Antarctic Place-Names Committee in 1959 because of their position on the fringe of the ships' passage between the Saffery Islands and the Trump Islands.

Trickster Rocks is a several small rocks emerging from the sea less than 1 nautical mile (1.9 km) northwest of Chavez Island in Grandidier Channel, off the west coast of Graham Land. So named by United Kingdom Antarctic Place-Names Committee (UK-APC) because the rocks escaped notice of the 1957 Falkland Islands Dependencies Survey (FIDS) survey party, as they were thought to be icebergs. The feature was photographed by Hunting Aerosurveys Ltd., 1957-58.

Pod Rocks

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.

Pesky Rocks is a small group of rocks lying 3.5 nautical miles (6 km) west of Cape Evensen, off the west coast of Graham Land. Shown on a Chilean government chart of 1947. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 because the rocks obstruct an otherwise clear shipping route.

Garnet Rocks

The Garnet Rocks are a group of three rocks lying 4 kilometres (2 nmi) east of the Refuge Islands in the northern part of Rymill Bay, off the west coast of Graham Land, Antarctica. They were first surveyed in 1948–49 by the Falkland Islands Dependencies Survey and so named by them because of the occurrence of garnet in the rocks.

The Gaunt Rocks are a small group of rocks lying 2 nautical miles (4 km) west of the Barros Rocks, in the Wilhelm Archipelago. They were roughly charted by the British Graham Land Expedition under John Rymill, 1934–37, and more accurately positioned by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57. The name, given by the UK Antarctic Place-Names Committee in 1959, is descriptive of these desolate, grim-looking rocks.

The Gedges Rocks are a group of rocks located 3 nautical miles (6 km) north-northwest of Grim Rock and 10 nautical miles (19 km) west-southwest of Cape Tuxen, off the west coast of Graham Land, Antarctica. They were discovered by the British Graham Land Expedition, 1934–37, and named "Gedges Reef" after The Gedges, a dangerous reef off the mouth of the Helford River in Cornwall, England. In 1971 the UK Antarctic Place-Names Committee reported that the term rocks is more appropriate for this feature.

Moss Islands

The Moss Islands are a group of small islands and rocks lying east of Midas Island and north of Apéndice Island in Hughes Bay, off the west coast of Graham Land, Antarctica. They were first charted in detail and given the descriptive name "Moos Inseln" by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902.

The Minnows are a group of small islands and rocks lying east of Flounder Island in the Fish Islands, off the west coast of Graham Land, Antarctica. They were charted by the British Graham Land Expedition under John Rymill, 1934–37, and were so named by the UK Antarctic Place-Names Committee in 1959 because the group lies in the Fish Islands, and "minnow" is a term for a small fish.

The Matsuyama Rocks are a small group of rocks close off the west side of Stefan Ice Piedmont, Graham Land, Antarctica. They are located towards the western end of Crystal Sound. They were mapped from air photos taken by the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and were named by the UK Antarctic Place-Names Committee after Motonori Matsuyama, Professor of Geology and Geophysics at Kyoto University, Japan, who made laboratory studies of the crystal forms of ice.

Tiber Rocks

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

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.
