The George VI and Queen Elizabeth Memorial, situated between The Mall and Carlton Gardens in central London, is a memorial to King George VI and his consort, Queen Elizabeth The Queen Mother.
 Completed in its present form in 2009, the memorial incorporates an earlier, Grade II-listed statue of George VI by William McMillan, unveiled by his daughter Queen Elizabeth II in 1955.
 The reconfigured memorial, which includes a statue of the Queen Mother by Philip Jackson, relief sculpture by Paul Day and an architectural setting by Donald Buttress and Donald Insall, was unveiled by Elizabeth II in 2009.
Group Captain Peter Wooldridge Townsend, (22 November 1914 – 19 June 1995) was a Royal Air Force officer, flying ace, courtier and author.
 He was Equerry to King George VI from 1944 to 1952 and held the same position for Queen Elizabeth II from 1952 to 1953.
 Townsend also had a romance with Princess Margaret.
Goodenough Glacier ( ) is a broad sweeping glacier to the south of the Batterbee Mountains, flowing from the west shore of Palmer Land, Antarctica, into George VI Sound and the George VI Ice Shelf.
 It was discovered in 1936 by A. Stephenson, W.L.S. Fleming, and George C.L. Bertram of the British Graham Land Expedition under John Rymill, while exploring George VI Sound, and was named by Rymill after Margaret Goodenough, wife of Admiral Sir William Goodenough, the latter being one of Rymill's principal supporters in raising funds for the expedition.
Hodgson Lake is a perennially ice-covered freshwater lake, which is about 2 km (1.2 mi) long by about 1.5 km (0.93 mi) wide.
 It is located within the southern part of Alexander Island, west of Palmer Land in Antarctica, at approximately 72°S latitude and 68°W longitude.
 This lake has a 93.4 m (306 ft) deep water column that lies sealed beneath a 3.6 to 4.0 m (12 to 13 ft) thick perennial lake ice.
 The lake is an ultra-oligotrophic lake with very low nutrient content and very low productivity.
 There is no detectable life living in Hodgson Lake.
 The lake extends eastward into George VI Sound and the George VI Ice Shelf making it adjacent to the sound.
 The northern side of this lake is bounded by the Saturn Glacier, which flows east into George VI Sound.
 The lake lies next to and southeast of Citadel Bastion, a pre-eminent mountain on Alexander Island.
George VI Sound or Canal Jorge VI or Canal Presidente Sarmiento or Canal Seaver or King George VI Sound or King George the Sixth Sound is a major bay/fault depression, 300 miles (483 km) long in the shape of the letter J, which skirts the east and south shores of Alexander Island, separating it from Palmer Land, in the southern portion of the Antarctic Peninsula and the English Coast.
 Various lakes are adjacent to the sound, these lakes receive large amounts of ice flowing from George VI Ice Shelf into the mouth of these lakes.
 Some of these include Hodgson Lake, Moutonnee Lake and Ablation Lake.
 Several glaciers also flow eastward into the sound from the east interior of Alexander Island, the vast majority of these glaciers are situated south of Planet Heights, where all of these glaciers are named after moons, satellites and planets of the solar system in association with nearby Planet Heights which was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1977.
The George VI Ice Shelf ( ) is an extensive ice shelf that occupies George VI Sound which separates Alexander Island from Palmer Land in Antarctica.
 The ice shelf extends from Ronne Entrance, at the southwest end of the sound, to Niznik Island, about 30 nmi south of the north entrance between Cape Brown and Cape Jeremy.
 It was named by the UK Antarctic Place-Names Committee in association with George VI Sound.
Benjamin Charles Miles (born 1 November 1966) is an English actor, best known for his starring role as Patrick Maitland in the British TV comedy "Coupling", from 2000 to 2004 and as Peter Townsend in the Netflix drama "The Crown" (2017).
Moutonnée Lake is a sub-glacial lake that lies within Moutonnee Valley, marginal to the George VI Ice Shelf, 7 km south of Ablation Point indenting the east coast of Alexander Island, facing the west coast of Palmer Land, Antarctica.
 Following limnological and tidal studies by the British Antarctic Survey (BAS) from 1971, it was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) from the presence of roche moutonnées on its shores.
 As with nearby Ablation and Hodgson Lakes, Moutonnée receives large masses of ice from the adjacent George VI Ice Shelf in George VI Sound, making life in the lake unsustainable.
 The site lies within Antarctic Specially Protected Area (ASPA) No.147.
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.
 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.
 Alexander Island is about 240 mi long in a north-south direction, 50 mi wide in the north, and 150 mi wide in the south.
 Alexander Island is the second largest uninhabited island in the world, after Devon Island.
Ronne Entrance is a broad southwest entrance of the George VI Sound where it opens from the southeast portion of the Bellingshausen Sea at the southwest side of Alexander Island, Antarctica.
 The south side of the Monteverdi Peninsula occupies the north portion of the Ronne Entrance while Ellsworth Land occupies the southern portion of the entrance.
 The entrance receives much ice throughout the whole year mainly because the entrance protrudes eastward into the adjacent George VI Sound and the George VI Ice Shelf from the southwest section, the Ronne Entrance is also prone to ice flow from the Bach Ice Shelf (which separates the south side of the Beethoven Peninsula from the north side of the Monteverdi Peninsula) as well as receiving ice from the Wilkins Ice Shelf (mainly from the southernmost end of the ice shelf).
 There are a few islands situated within the Ronne Entrance, mainly in the southwest area.
 Some of these islands include the Eklund Islands, DeAtley Island, Spaatz Island, Case Island and Smyley Island.
 It was discovered on a sledge journey through the sound in December 1940 by U.S. Polar explorer Finn Ronne and Carl Eklund of the US Antarctic Service (USAS), 1939–41, and named "Ronne Bay".
 Finn Ronne covered more miles by ski and sled dog than any other explorer in history and mapped the last unknown coastline on earth on his Ronne Antarctic Research Expedition in 1947.
