Question: Where is the continental limit of the continent encompassing Tufft Nunatak?

full_context: Document 1: Faulkner Nunatak: Faulkner Nunatak () is a distinctive nunatak, about high, just west of Beagle Peak and 9.5 km west by south of Mount Devol in the Lassus Mountains, in the northwest part of Alexander Island, Antarctica. The feature appears in U.S. Navy aerial photographs obtained in 1966. It was named by the Advisory Committee on Antarctic Names after Harold T. Faulkner, U.S. Navy, Leading Chief of Squadron VXE-6 Photo Division on Operation Deep Freeze, 1969.
Document 2: 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 3: Abrit Nunatak: Abrit Nunatak (; \'nu-na-tak a-'brit\) is the rocky hill rising to over 400 m east of Laclavère Plateau on Trinity Peninsula in Graham Land, Antarctica. It is overlooking Mott Snowfield to the north and Retizhe Cove to the southeast.
Document 4: 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 5: Gratton Nunatak: Gratton Nunatak () is a bare, linear nunatak lying at the south side of the mouth of McCarthy Glacier, Antarctica, where the latter enters Reedy Glacier. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for John W. Gratton, a construction mechanic at Byrd Station in 1962.
Document 6: 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 7: 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 8: 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 9: Helfert Nunatak: Helfert Nunatak () is a prominent rock nunatak standing west of Mount Sharp of the Sentinel Range, in the Ellsworth Mountains of Antarctica. It was discovered and visited by the Marie Byrd Land Traverse party, 1957–58, under C.R. Bentley, and named for Norbert F. Helfert, a meteorologist at Byrd Station in 1957.
Document 10: Urguri Nunatak: Urguri Nunatak (, ‘Nunatak Urguri’ \'nu-na-tak ur-'gu-ri\) is the rocky hill rising to 560 m in the east foothills of Laclavère Plateau on Trinity Peninsula in Graham Land, Antarctica. It is overlooking Mott Snowfield to the north.
Document 11: Tufft Nunatak: Tufft Nunatak () is a small nunatak 3 nautical miles (6 km) southwest of Mount Bradley and 4.6 km south of Senokos Nunatak, Trinity Peninsula in Graham Land, Antarctica. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Roger Tufft of the Falkland Islands Dependencies Survey (FIDS), a member of the reconnaissance party for the Detroit Plateau journey in February 1957.
Document 12: Stephenson Nunatak: Stephenson Nunatak () is a prominent, pyramid-shaped rock nunatak, rising to about 640 m, which rises 300 m above the surrounding ice at the northwest side of Kirwan Inlet in the southeast part of Alexander Island, Antarctica. Discovered and roughly surveyed in 1940-41 by Ronne and Eklund of the United States Antarctic Service. Resurveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for Alfred Stephenson, surveyor with the British Graham Land Expedition, who led a sledge party south into George VI Sound to about 72S in 1936. There happens to be another landform on Alexander Island which is named after Alfred Stephenson, that being Mount Stephenson, the highest point of Alexander Island rising to 2,987 m.
Document 13: 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 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: Tufts Pass: Tufts Pass () is a pass extending in an east-west direction between the Rouen Mountains and the Elgar Uplands in the north part of Alexander Island, Antarctica. The mountain pass was probably first sighted from the air and roughly mapped by the British Graham Land Expedition in 1937. Remapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named by the RARE for Tufts University, Medford, Massachusetts, United States, where Dr. Robert Nichols was head of the geology department before joining the RARE.
