The Gedges Rocks ( 65°20′S64°32′W / 65.333°S 64.533°W Coordinates: 65°20′S64°32′W / 65.333°S 64.533°W ) 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. [1]
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.
Grim Rock is a rock awash 3 nautical miles (6 km) south-southeast of the Gedges Rocks and 10 nautical miles (19 km) west-northwest of Cape Perez, lying in Grandidier Channel off the west coast of Graham Land, Antarctica. It was charted in February 1936 by the British Graham Land Expedition under John Rymill, and so named from its grim appearance.
Cape Tuxen is a rocky cape forming the south side of the entrance to Waddington Bay on Kiev Peninsula, the west coast of Graham Land. Discovered and named by the Belgian Antarctic Expedition, 1897–99, under Gerlache.
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.
Aphrodite Glacier is a glacier 15 nautical miles (28 km) long flowing north to the east coast of the Antarctic Peninsula 3 nautical miles (6 km) west of Victory Nunatak. The lower portion of the feature was first plotted by W.L.G. Joerg from aerial photographs taken by Sir Hubert Wilkins in December 1928 and by Lincoln Ellsworth in November 1935. The glacier was subsequently photographed by the Ronne Antarctic Research Expedition in December 1947 and surveyed by the Falkland Islands Dependencies Survey in December 1958 and November 1960. It was named by the UK Antarctic Place-Names Committee after Aphrodite, the goddess of love in Greek mythology.
The Barros Rocks are a group of rocks between the Berthelot Islands and the Argentine Islands, lying 2 nautical miles (4 km) southwest of Cape Tuxen off the west coast of Graham Land.

The Kramer Rocks are two rocks lying in the northern part of Beascochea Bay, 3 nautical miles (10 km) southeast of Cape Perez on the west coast of Graham Land, Antarctica. They were mapped by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57, and were named by the UK Antarctic Place-Names Committee in 1959 for J.G.H. Kramer, an Austrian army physician who independently recognized scurvy as a nutritional deficiency disease and showed how it could be prevented or cured, in about 1737.
The Frost Rocks are a cluster of rocks situated southwest of the southern Argentine Islands and 0.5 nautical miles (1 km) southwest of the Whiting Rocks, off the coast of Graham Land, Antarctica. They were named by the UK Antarctic Place-Names Committee for Richard Frost, a survey assistant of the Hydrographic Survey Unit from HMS Endurance working in the area in February 1969.
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.
Puzzle Islands is a group of small islands, rocks and reefs at the mouth of Flandres Bay, lying 1 nautical mile (1.9 km) west of Menier Island off the west coast of Graham Land. First charted by the French Antarctic Expedition under Charcot, 1903-05. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1958; the group is often hidden by icebergs which come to rest in the surrounding shallow waters.
Pythia Island is an island 0.2 nautical miles (0.4 km) long, the largest of a group of small islands off the east side of Enterprise Island in Wilhelmina Bay, off the west coast of Graham Land.

The Gaunt Rocks are a small group of rocks lying 2 nautical miles (4 km) west of the Barros Rocks, in the Wilhelm Archipelago.

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.
