Question: Where is the continental limit of the continent where Polaris Glacier is located?

full_context: Document 1: 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 2: Pluto Glacier: Pluto Glacier () is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 4 nautical miles (7 km) wide, which flows east into George VI Sound to the north of Succession Cliffs. Although Pluto Glacier is not located within nearby Planet Heights, the glacier was named in association with the mountain range along with many other nearby glaciers that are named after planets of the Solar System. The glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Roughly surveyed in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Pluto, then considered the ninth (and last) planet of the Solar System, following Falkland Islands Dependencies Survey (FIDS) surveys in 1948 and 1949.
Document 3: Zasele Peak: Zasele Peak (, ‘Vrah Zasele’ \'vr&h za-'se-le\) is the ice-covered peak rising to 1250 m in the southeast foothills of Detroit Plateau on Nordenskjöld Coast in Graham Land, Antarctica, situated between the upper courses of Polaris and Pyke Glaciers. It has precipitous and partly ice free west slopes.
Document 4: Polaris Glacier: Polaris Glacier () is a distinctive glacier, 4 nautical miles (7 km) long, flowing southward from Detroit Plateau, between Pyke and Eliason Glaciers on Nordenskjöld Coast in northern Graham Land, Antarctica. Mapped from surveys by Falkland Islands Dependencies Survey (FIDS) (1960–61). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after the "Polaris" motor sledge made by Polaris Industries, Roseau, Minnesota, and used in Antarctica since 1960.
Document 5: 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 6: 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 7: Flask Glacier: Flask Glacier (), is a gently-sloping glacier, long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the "Pequod" in Herman Melville's "Moby-Dick; or, The White Whale".
Document 8: Spartan Glacier: Spartan Glacier () is a short valley glacier lying between Callisto Cliffs and Tombaugh Cliffs on the east side of Alexander Island, Antarctica. The glacier was first mapped by the Overseas Surveys Directorate from satellite imagery supplied by U.S. National Aeronautics and Space Administration in cooperation with U.S. Geological Survey. Named by United Kingdom Antarctic Place-Names Committee after the British dog team known as "The Spartans," used in ascending this glacier, 1969. This is one of the few glaciers in Antarctica to be named after a dog team.
Document 9: Endurance Glacier: Endurance Glacier is a broad glacier north of Mount Elder, draining south-east to the south coast of Elephant Island in the South Shetland Islands of Antarctica, and is the main discharge glacier on the island. It was named by the UK Antarctic Place-Names Committee after HMS "Endurance" (Captain P.W. Buchanan, Royal Navy), which anchored off the glacier on several occasions in support of the Joint Services Expedition to Elephant Island, 1970–71.
Document 10: 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.
Document 11: 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 12: Leverett Glacier: Leverett Glacier in Antarctica is about long and wide, draining northward from the Watson Escarpment, between California Plateau and Stanford Plateau, and then trending west-northwest between the Tapley Mountains and Harold Byrd Mountains to terminate at the head of the Ross Ice Shelf close east of Scott Glacier. It was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by him for Frank Leverett, an eminent geologist at the University of Michigan and an authority on the glacial geology of the central United States.
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: 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 15: 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).
