First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Timothy M.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Dogs Leg Fjord is an inlet 6 nautical miles (11 km) long in an east-west direction and 1.5 nautical miles (3 km) wide, lying south of German Peninsula, directly east of Ridge Island and opening on Bourgeois Fjord, along the Fallières Coast on the west side of Graham Land, Antarctica. It was discovered by the British Graham Land Expedition, 1934–37, under John Rymill, and so named because of its shape.

Square Bay is a bay, roughly square in outline and 10 nautical miles (18 km) wide, indenting the west coast of Graham Land between Nicholl Head and Camp Point. Most of the entrance to the bay is occupied by Horseshoe Island, which limits access to a narrow southern strait opening onto Marguerite Bay and a narrower northwestern strait opening onto the mouth of Bourgeois Fjord. Mapped and named by the British Graham Land Expedition (BGLE), 1934–37, under Rymill.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Ernest Bevin, M.P., British Minister of Labour and National Service and member of the War Cabinet.

Bottrill Head is a rugged headland on the east side of Bourgeois Fjord which forms the southwest extremity of German Peninsula and the north side of the entrance to Dogs Leg Fjord in Fallières Coast, on the west side of Graham Land, Antarctica. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill. The headland was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) who named it for Harold Bottrill, Chairman of the Board of Directors, later General Manager, of Maclean and Stapledon S.A., shipping agents at Montevideo, who gave great assistance to the BGLE, 1934–37, and to FIDS, 1943–48.

Contact Peak is a prominent rock peak, 1,005 metres (3,300 ft) high, which is the southeasternmost peak on Pourquoi Pas Island, off the west coast of Graham Land. It was first sighted and roughly charted in 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot. It was surveyed in 1936 by the British Graham Land Expedition and in 1948 by the Falkland Islands Dependencies Survey (FIDS). It was so named by FIDS because the peak marks the granite-volcanic contact in the cliffs which is visible at a considerable distance.

Nautilus Head is a prominent headland rising to 975 m near the northeast extremity of Pourquoi Pas Island, off the west coast of Graham Land. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill and resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) who named it after the submarine Nautilus in Jules Verne's Twenty Thousand Leagues Under The Sea. Other features on Pourquoi Pas Island are named after characters from that book.

Resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and so named by them because of the curious and unidentified whistling sounds heard there at the time of the survey.

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.

First surveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because of the friable nature of the rock found on the island.

Perplex Ridge is a ridge, rising over 915 m, composed of four rocky masses separated by small glaciers, extending 6 nautical miles (11 km) northeastward from Lainez Point along the northwest side of Pourquoi Pas Island, off the west coast of Graham Land. First sighted and roughly charted in 1909 by the French Antarctic Expedition under Charcot. It was surveyed in 1936 by the British Graham Land Expedition (BGLE) and in 1948 by the Falkland Islands Dependencies Survey (FIDS). So named by FIDS because of confusion in attempting to identify this ridge from earlier maps.

The mouth of the glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. The entire glacier was surveyed in 1946-47 and 1948-49 by the Falkland Islands Dependencies Survey (FIDS), and named by them for Max F.

Thomson Head is a steep, rocky headland rising to 915 m at the east side of Bourgeois Fjord, between Perutz and Bader Glaciers, forming the north extremity of German Peninsula on Fallières Coast on the west side of Graham Land, Antarctica. First surveyed in 1936 by the British Graham Land Expedition (BGLE) under Rymill. Resurveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS) and named for William H. Thomson, FIDS air pilot at Stonington Island in 1947.

The Forbidden Plateau is a long, narrow plateau extending southwestward from Charlotte Bay to Flandres Bay in Graham Land. It borders Bruce Plateau on the south and Foster Plateau on the north. The feature was mapped by the Falklands Islands Dependencies Survey (FIDS) from photos taken by Hunting Aerosurveys Ltd. in 1956-57. Its name was picked by the UK Antarctic Place-names Committee (UK-APC) because all attempts to reach the plateau failed until it was finally traversed by Falklands Islands Dependencies Survey (FIDS) members in 1957.
