Question: Where is the continental limit of the continent on which Grikurov Ridge is located?

full_context: Document 1: 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 2: 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 3: King Ridge: King Ridge () is a narrow rock ridge, long, lying southwest of Wrigley Bluffs in the Anderson Hills in the central Patuxent Range of the Pensacola Mountains, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1956–66. The ridge was named by the Advisory Committee on Antarctic Names at the suggestion of Captain Finn Ronne, U.S. Navy Reserve, leader at Ellsworth Station, 1957: Colonel J. Caldwell King, U.S. Army, had assisted Ronne in obtaining support for the Ronne Antarctic Research Expedition, 1947–48.
Document 4: Pagoda Ridge: Pagoda Ridge () is a ridge with a small peak resembling a pagoda at the summit, located between Phobos Ridge and Deimos Ridge on the north side of Saturn Glacier, in southeast Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, during 1947 and 1948, and from surveying by the Falkland Islands Dependencies Survey, 1948-50. This descriptive name was applied by the United Kingdom Antarctic Place-Names Committee.
Document 5: Gorki Ridge: Gorki Ridge () is a ridge about long forming the east wall of Schussel Cirque in the Humboldt Mountains of Queen Maud Land, Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938-39, and mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60. It was remapped by the Soviet Antarctic Expedition, 1960–61, and named after Soviet author A.M. Gorki.
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: 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: Himalia Ridge: Himalia Ridge is a ridge running east–west on the north side of the Ganymede Heights massif, north-east of Jupiter Glacier, in the east of Alexander Island, Antarctica. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. The ridge was named by the UK Antarctic Place-Names Committee following British Antarctic Survey geological work, 1983–84, after Himalia, a satellite of the planet Jupiter, in association with Jupiter Glacier. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Document 9: Galan Ridge: Galan Ridge is a prominent ridge which forms the northeastern rampart of the Dana Mountains in Palmer Land, Antarctica. It was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1961–67, and was named by the Advisory Committee on Antarctic Names for Michael P. Galan, a member of the McMurdo Station winter party in 1967 and of the South Pole—Queen Maud Land Traverse III in 1967–68.
Document 10: 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 11: 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 12: Frame Ridge: Frame Ridge () is a small straight ridge in the central part of Brown Peninsula, Victoria Land, Antarctica. It is located just north of the small, central lake on the peninsula and extends northward down to Tuff Bluff. It was named by the New Zealand Antarctic Place-Names Committee for Alexander Oswald Frame, a paleontology technician with the New Zealand Geological Survey and Victoria University of Wellington who discovered the ridge on an expedition to the area, 1964–65.
Document 13: 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 14: 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 15: Grikurov Ridge: Grikurov Ridge () is a ridge that extends westward for about from the south end of the LeMay Range, in central Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. It was named by the UK Antarctic Place-Names Committee for the Russian Garrik Grikurov, a Soviet exchange geologist with the British Antarctic Survey, who worked in this area in 1963–64.
