Perce Point
Perce Point () is a low ice-covered headland 12 nautical miles (22 km) west-northwest of Berlioz Point on the southern coast of the Beethoven Peninsula, situated in the southwest portion of Alexander Island, Antarctica. The headland was first discovered by Snow, Perce and Carroll of the United States Antarctic Service (USAS) expedition in a flight from Stonington Island on December 22, 1940. Originally named "Cape Perce" after Earl B. Perce, co-pilot of the discovery aircraft, but the term point is considered appropriate for this feature.

Berlioz Point
Berlioz Point () is a snow-covered headland on the south side of Beethoven Peninsula, Alexander Island, marking the northwest entrance point to the embayment occupied by Bach Ice Shelf. The south part of Alexander Island was first roughly mapped by the United States Antarctic Service in 1940, but this point was not clearly identified. It was mapped from air photos obtained by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and named by the UK Antarctic Place-Names Committee after the French composer Hector Berlioz.

Beethoven Peninsula
The Beethoven Peninsula is a deeply indented, ice-covered peninsula, long in a northeast–southwest direction and wide at its broadest part, forming the southwest part of Alexander Island, which lies off the southwestern portion of the Antarctic Peninsula. The south side of the peninsula is supported by the Bach Ice Shelf whilst the north side of the peninsula is supported by the Wilkins Ice Shelf. The Mendelssohn Inlet, the Brahms Inlet and the Verdi Inlet apparently intrude into it. The Bach Ice Shelf, Rossini Point and Berlioz Point are some distance away, on the Ronne Entrance from the Southern Ocean. Beethoven Peninsula is one of the eight peninsulas of Alexander Island. The peninsula was first seen and photographed from the air in 1940 by the US Antarctic Service, which compiled the first rough map of southwest Alexander Island. It was resighted and photographed from the air by the Ronne Antarctic Research Expedition (RARE), 1947–48, and remapped from RARE photo ...

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south.

United States Antarctic Service
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Stonington Island
Stonington Island is a rocky island lying northeast of Neny Island in the eastern part of Marguerite Bay off the west coast of Graham Land, Antarctica. It is long from north-west to south-east and wide, yielding an area of . It was formerly connected by a drifted snow slope to Northeast Glacier on the mainland. Highest elevation is ''Anemometer Hill'' which rises to . History Stonington Island was chosen as the site for the East Base of the United States Antarctic Service (USAS) Expedition (1939–41). It was named after Stonington, Connecticut, home port of the sloop ''Hero'' in which Captain Nathaniel Palmer sighted the Antarctic continent in 1820. Station E The island was also home to the British Antarctic Survey (BAS) Station E and the Ronne Antarctic Research Expedition, and was the base of operations for many historic Antarctic Peninsula surveying missions in the 1940s. Station E was occupied until 23 February 1975 and the main building was known as Trepassey House, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ablation Point
Ablation Point, also known as Punta Ablación, is the eastern extremity of a hook-shaped rock ridge marking the north side of the entrance to Ablation Valley, on the east coast of Alexander Island, Antarctica. It was first photographed from the air on 23 November 1935 by Lincoln Ellsworth and mapped from these photographs by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). It was named by FIDS for nearby Ablation Valley.Stewart, J., 2011. ''Antarctica: An Encyclopedia,'' 2nd ed. Jefferson, North Carolina and London, McFarland & Company, Inc. 1771 pp. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
