Location of King George Island in the South Shetland Islands.

Simpson Rocks ( 61°58′S57°23′W / 61.967°S 57.383°W / -61.967; -57.383 Coordinates: 61°58′S57°23′W / 61.967°S 57.383°W / -61.967; -57.383 ) is a group consisting of a rock, 10 m high, surrounded by sunken rocks, lying 5 nautical miles (9 km) northeast of Cape Melville, King George Island, in the South Shetland Islands. The name "Simpsons Islands" appears on a chart of 1825 by British sealer James Weddell, but the term "rocks" is considered more descriptive than "islands".

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.

South Shetland Islands A group of islands north of the Antarctic Peninsula

The South Shetland Islands are a group of Antarctic islands with a total area of 3,687 square kilometres (1,424 sq mi). They lie about 120 kilometres (75 mi) north of the Antarctic Peninsula, and between 430 kilometres (270 mi) to 900 kilometres (560 mi) south-west from the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.

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.

Geographic Names Information System geographical database

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.

Seal Islands (South Shetland Islands) group of the South Shetland Islands

The Seal Islands are a group of small islands and rocky islets lying about 7 km north and north-west of Elephant Island, in the South Shetland Islands of Antarctica. They extend east–west for about 5 km, and are separated from Elephant Island by Sealers Passage. The group takes its name from the largest island, which Captain William Smith named Seal Island in 1820 because of the number of seals killed there.

Meade Nunatak is a nunatak 3 nautical miles (6 km) north of Blanchard Hill, rising to 990 metres (3,250 ft) in the Pioneers Escarpment, Shackleton Range, Antarctica. It was photographed from the air by the U.S. Navy, 1967, and was surveyed by the British Antarctic Survey, 1968–71. In association with the names of pioneers of polar life and travel grouped in this area, it was named by the UK Antarctic Place-Names Committee in 1971 after English mountaineer Charles Francis Meade, the designer of the Meade tent.

Aitkenhead Glacier glacier in Antarctica

Aitkenhead Glacier is a 10-mile (16 km) long glacier flowing east-southeast from the Detroit Plateau, Graham Land, into Prince Gustav Channel. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and named by the United Kingdom Antarctic Place-Names Committee for Neil Aitkenhead, a FIDS geologist at Hope Bay (1959–60).

Böhnecke Glacier is a steep glacier 3 nautical miles (6 km) wide, which flows southeast to the northwest side of Violante Inlet, on the east coast of Palmer Land. It was discovered and photographed from the air in December 1940 by members of the United States Antarctic Service. During 1947 the glacier was photographed from the air by members of the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named by FIDS for Gunther Böhnecke, a German oceanographer and a member of the German expedition in the Meteor, 1925–27.

Bolinder Bluff is a prominent bluff crowned by three buttresses of dark grey and light brown rock, overlooking Venus Bay 3 nautical miles (6 km) southeast of False Round Point on the north coast of King George Island, in the South Shetland Islands. The feature was known to sealers using the anchorage at nearby Esther Harbor in the 1820s. It was charted and named by Discovery Investigations personnel on the Discovery II in 1937 when the breakdown of the Bolinder boat engine caused 6 men to be marooned for 9 days on the beach at the foot of the bluff.

It was mapped in 1959 by the Falkland Islands Dependencies Survey from photos taken by Hunting Aerosurveys Ltd in 1956–57, and named by the UK Antarctic Place-Names Committee for William B. Bolton (1848–89), English photographer who, with B.J. Sayce, invented the collodion emulsion process of dry-plate photography in 1864.
