Question: What is the continental limit of the continent where VXE-6 was located?

full_context: Document 1: Antarctic Peninsula: The Antarctic Peninsula, known as O'Higgins Land in Chile, Tierra de San Martin in Argentina, and originally known as the Palmer Peninsula in the US and as Graham Land in Great Britain, is the northernmost part of the mainland of Antarctica, located at the base of the Southern Hemisphere.
Document 2: Airdevronsix Icefalls: Airdevronsix Icefalls () is a line of icefalls at the head of Wright Upper Glacier, in Victoria Land, Antarctica. Named by U.S. Navy Operation Deepfreeze (1956–57) for "U.S. Navy Air Development Squadron Six", which had been formed to provide air support for the Deep Freeze operations and which had also carried out many important Antarctic exploratory flights.
Document 3: Antarctica: Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.
Document 4: Chapel of the Snows: The Chapel of the Snows is a non-denominational Christian church located at the United States' McMurdo Station on Ross Island, Antarctica and is one of eight churches on Antarctica. The chapel is the second southernmost religious building in the world and has regular Catholic and Protestant services. During the Austral Summer, the chapel is staffed by rotational chaplains. The U.S. Air National Guard supplies Protestant chaplains and the Diocese of Christchurch supplies Catholic priests. The chapel is also host to services and meetings for other faith groups such as Latter Day Saints, Baha'i, and Buddhism and non-religious groups such as Alcoholics Anonymous. These meetings are dependent on lay leadership to be the points of contact and facilitators. The building itself may hold up to 63 worshippers.
Document 5: Mirounga Point: Mirounga Point () is the east entrance point to Potter Cove, King George Island, in the South Shetland Islands off Antarctica. The feature was called "Punta Baliza" (beacon point) by R. Araya and F. Herve in 1966. It was later called "Punta Elefante" by the Argentine Antarctic Expedition after the elephant seal ("Mirounga leonina"), in connection with the establishment of Site of Special Scientific Interest number 13 (now Antarctic Specially Protected Area 132) in this vicinity under the Antarctic Treaty. The approved name avoids the duplication of Elephant Point on Livingston Island.
Document 6: Antarctica: Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.
Document 7: Emilio Palma: Emilio Marcos Palma (born 7 January 1978) is an Argentine man known for being the first documented person born on the continent of Antarctica.
Document 8: Chileans: Though the majority of Chileans reside in Chile, significant communities have been established in multiple countries, most noticeably Argentina, United States, Australia and Canada and countries of the European Union. Although small in number, Chilean people also make up a substantial part of the permanent population of Antarctica and the Falkland Islands (see: Chileans in the Falkland Islands).
Document 9: Refuge Astronomer Cruls: The refuge, which can accommodate up to 6 scientists for up to 40 days, depends both logistically and administratively on Comandante Ferraz station. Together with Refuge Emílio Goeldi, located on Elephant Island, constitute the basic infra-structure to support the Brazilian Antarctic Program in Antarctica.
Document 10: VX-31: Air Test and Evaluation Squadron 31 (VX-31 or AIRTEVRON THREE ONE, commonly referred to by its nickname, The Dust Devils) is a United States Navy air test and evaluation squadron based at Naval Air Weapons Station China Lake, California. Using the tail code "DD", they fly numerous United States Navy and United States Marine Corps fixed-wing aircraft and helicopters.
Document 11: Chinstrap Point: Chinstrap Point is the southeast point of Vindication Island, South Sandwich Islands. This feature was named Rocky Point during a survey of the island from RRS "Discovery II" in 1930, but the name was changed to avoid duplication. The new name applied by the UK Antarctic Place-Names Committee in 1971 refers to the enormous colony of chinstrap penguins on the point.
Document 12: VXE-6: Antarctic Development Squadron Six (VXE-6 or ANTARCTIC DEVRON SIX, commonly referred to by its nickname, The Puckered Penguins) was a United States Navy Air Test and Evaluation Squadron based Naval Air Station Point Mugu, California with forward operating bases at Christchurch, New Zealand and McMurdo Station, Antarctica.
Document 13: Antarctica: New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.
Document 14: Chilean Antarctic Territory: The Chilean Antarctic Territory or Chilean Antarctica (Spanish: "Territorio Chileno Antártico", "Antártica Chilena") is the territory in Antarctica claimed by Chile. The Chilean Antarctic Territory ranges from 53° West to 90° West and from the South Pole to the 60° South parallel, partially overlapping the Argentine and British Antarctic claims. It is administered by the Cabo de Hornos municipality in the South American mainland.
Document 15: Antarctica: The first semi-permanent inhabitants of regions near Antarctica (areas situated south of the Antarctic Convergence) were British and American sealers who used to spend a year or more on South Georgia, from 1786 onward. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken, Leith Harbour, King Edward Point, Stromness, Husvik, Prince Olav Harbour, Ocean Harbour and Godthul. Managers and other senior officers of the whaling stations often lived together with their families. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910.
