Question: What is the name of the capital located at in Cumberland East Bay that Mount Duse is surmounting ?

full_context: Document 1: Edward VIII Bay: Edward VIII Bay is a bay about 20 mi in extent, located between Edward VIII Plateau (a dome-shaped, ice-covered peninsula near Magnet Bay) and the Øygarden Group of islands. The head of the bay is occupied by the Edward VIII Ice Shelf. The bay was discovered in 1936 by Discovery Investigations personnel on the RRS "William Scoresby", and named for Edward VIII, then King of the United Kingdom.
Document 2: Cumberland East Bay: Cumberland East Bay is a bay forming the eastern arm of Cumberland Bay, South Georgia. It is entered between Sappho Point and Barff Point, where it is nearly 3 mi wide, and extends 8 mi in a southeast direction. This feature was surveyed by the Swedish Antarctic Expedition, 1901–04, who named it "South Bay". It was remapped during 1926–29 by Discovery Investigations personnel and renamed "East Cumberland Bay", which is more descriptive of its geographic position. The shortened form "East Bay" was simultaneously used. Following the South Georgia Survey, 1951–52, the UK Antarctic Place-Names Committee proposed that the name be altered to Cumberland East Bay and that all other names be rejected. This change brings together information about the whole of Cumberland Bay in one place in indexes, and will avoid confusion with East Bay in Prince Olav Harbour, South Georgia.
Document 3: Mount Friesland: Mount Friesland is a mountain rising to 1700.2 m in the homonymous Friesland Ridge, the summit of Tangra Mountains and Livingston Island in the South Shetland Islands, Antarctica. Its north rib is connected to Pliska Ridge by Nesebar Gap on the west, and to Bowles Ridge by Wörner Gap on the north. On the east Mount Friesland is connected to Presian Ridge and further on to Catalunyan Saddle and Lyaskovets Peak. On the south-southwest it is connected by a short saddle to ‘The Synagogue’ a sharp-peaked rock-cored ice formation abutting neighbouring St. Boris Peak. The peak is heavily glaciated and crevassed, surmounting Huntress Glacier to the west, Perunika Glacier to the north-northwest, Huron Glacier to the northeast and Macy Glacier to the southeast. The local weather is notoriously unpleasant and challenging; according to the seasoned Antarctic mountaineer Damien Gildea who climbed in the area, 'just about the worst weather in the world'.
Document 4: Mount Cunningham: Mount Cunningham is a mountain at the west end of South Georgia's Esmark Glacier. It is situated between Jossac Bight and Queen Maud Bay. With an elevation of 1218 m , it is the 16th highest mountain in South Georgia. The mountain was named after Scottish mountaineer John Crabbe Cunningham as a memorial after his death on 31 January 1980, following a climbing accident when struck by waves off Holyhead.
Document 5: King Edward Point: King Edward Point (also known as KEP) is the capital of South Georgia and the South Sandwich Islands, on the northeastern coast of the island of South Georgia. It is located at in Cumberland East Bay. It is sometimes confusingly referred to as Grytviken, which is the site of the disused whaling station, nearby at the head of King Edward Cove.
Document 6: Mount Hodges: Mount Hodges ( ) is a mountain, 605 m high, standing 1 nmi west of Mount Duse, close northwest of the head of King Edward Cove, Cumberland East Bay, South Georgia. It was first roughly surveyed by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskjöld, appearing as "Moldaenke Berg" on a 1907 map by A. Szielasko, but the name has not survived on later general charts of this area. The name "Mount Hodges" appears to have been applied some years later and is now well established. It was probably named for Captain M.H. Hodges, Royal Navy, of the "Sappho", who visited and mapped portions of Cumberland Bay in 1906.
Document 7: Sappho Point: Sappho Point ( ) is a headland which marks the west side of the entrance to Cumberland East Bay, on the north coast of South Georgia. Probably first sighted by the British expedition under Cook which explored the north coast of South Georgia in 1775. Named for HMS Sappho, British ship used in charting portions of Cumberland Bay in 1906.
Document 8: Mount Amundsen: Mount Amundsen is a nunatak lying east of Denman Glacier, about 11 nautical miles (20 km) northeast of Mount Sandow. It was discovered by the Western Base Party of the Australasian Antarctic Expedition (1911–14) under Mawson, and named by Mawson for Roald Amundsen, the Norwegian polar explorer, who was the first to attain the South Pole.
Document 9: Du Toit Mountains: The Du Toit Mountains ( ) are a group of mountains about 35 mi long and 10 mi wide, to the south-west of the Wilson Mountains in southeastern Palmer Land, Antarctica. The mountains have peaks rising to 1,700 m and are bounded by Beaumont Glacier, Maury Glacier and Defant Glacier. They were first photographed from the air by the U.S. Antarctic Service in 1940; rephotographed by the U.S. Navy, 1966–69, and mapped from the photographs by the U.S. Geological Survey. In association with the names of continental drift scientists grouped in this area, they were named by the Advisory Committee on Antarctic Names after Alexander du Toit, a South African geologist who was an early proponent of the theory of continental drift.
Document 10: King Edward Cove: King Edward Cove is a sheltered cove immediately southwest of Mount Duse, in the west side of Cumberland East Bay, South Georgia. This cove, frequented by early sealers at South Georgia, was charted by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskiöld. It was named in about 1906 for King Edward VII of the United Kingdom.
Document 11: Mount Duse: Mount Duse ( ) is a conspicuous mountain, 505 m high, surmounting King Edward Point on the west side of Cumberland East Bay, South Georgia. It was charted in 1902 by Lieutenant S.A. Duse, cartographer of the Swedish Antarctic Expedition, 1901–04, for whom it is named.
Document 12: Grytviken: Grytviken is a settlement on the island of South Georgia, part of a British Overseas Territory in the South Atlantic. The settlement's name is Swedish in origin, meaning "the Pot Bay". The name was coined in 1902 by the Swedish Antarctic Expedition and documented by the Swedish surveyor Johan Gunnar Andersson, after the expedition found old English try pots used to render seal oil at the site. It is the best harbour on the island, consisting of a bay (King Edward Cove) within a bay (Cumberland East Bay). The site is quite sheltered, provides a substantial area of flat land suitable for building, and has a good supply of fresh water.
Document 13: Mount Hassel: Mount Hassel ( ) is a rock peak 2,390 m high, the northeasternmost summit of the massif at the head of Amundsen Glacier, in the Queen Maud Mountains of Antarctica. In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen. Amundsen named one of them for Sverre Hassel, a member of the party. The peak described was mapped by the United States Geological Survey from surveys and U.S. Navy aerial photography, 1960–64. For the sake of historical continuity and to commemorate the Norwegian exploration in this area, the Advisory Committee on Antarctic Names has selected this feature to be designated Mount Hassel. Other peaks in the massif have also been named for members of Amundsen's South Pole Party.
Document 14: Thatcher Peninsula: Thatcher Peninsula ( ) is a mountainous peninsula in north-central South Georgia terminating to the north in Mai Point, rising between Cumberland West Bay to the west, and Cumberland East Bay and Moraine Fjord to the east; bounded to the southwest and south by Lyell Glacier and Hamberg Glacier. King Edward Cove on the east side of the peninsula is the site of the British Antarctic Survey (BAS) Grytviken station and the disused whaling station of the same name.
Document 15: Edward VIII Plateau: The Edward VIII Plateau is a dome-shaped, ice-covered peninsula between Magnet Bay and Edward VIII Bay. It was probably seen by personnel on the RSS "William Scoresby" in 1936, and mapped from aerial photos taken by the Lars Christensen Expedition, 1936-37, and named Gulfplataet (the gulf plateau). It was renamed "King Edward Plateau" by ANCA, but the form Edward VIII Plateau has been approved by the Advisory Committee on Antarctic Names (US-ACAN) to be consistent with the names of nearby Edward VIII Bay and Ice Shelf.
