Question: what is the continental limit where the Crosswell Glacier is found?

full_context: Document 1: 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 2: Ramorino Glacier: Ramorino Glacier () is the long glacier situated northwest of upper Crosswell Glacier and southeast of Cervellati Glacier on the east slope of Sentinel Range in the Ellsworth Mountains, Antarctica. It flows northeastwards between Epperly Ridge and Shinn Ridge, and enters Crosswell Glacier northwest of Mount Segers. The feature was named by US-ACAN in 2006 after Maria Chiara Ramorino, manager of the Italian team that compiled and promulgated the SCAR Composite Gazetteer of Antarctica, 1998-2006.
Document 3: Ferrigno Glacier: Ferrigno Glacier () is a broad glacier on the north side of Rampart Ridge, Victoria Land, Antarctica, flowing west-northwest from Mount Lynch and Bishop Peak to the vicinity of The Spire. It was named by the Advisory Committee on Antarctic Names in 1994 after Jane G. Ferrigno, a United States Geological Survey geologist, a specialist in the use of satellite imagery to study and map Antarctica, and other ice and snow areas throughout the world. She was co-editor (with Richard S. Williams, Jr.) of the "Satellite Image Atlas of Glaciers of the World".
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: 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 6: Forman Glacier: Forman Glacier () is a tributary glacier, long, flowing east to enter Shackleton Glacier between Mount Franke and Mount Cole, in the Queen Maud Mountains of Antarctica. It was named by the Advisory Committee on Antarctic Names after John H. Forman, Construction Mechanic, U.S. Navy, a member of the McMurdo Station winter party, 1959.
Document 7: Sowers Glacier: Sowers Glacier () is a glacier that flows from the prominent cirque on the east side of Craddock Massif and continues between Willis Ridge on the north, and Sanchez Peak and Stolnik Peak on the south, to join Thomas Glacier north of Mount Osborne, in the Sentinel Range, Ellsworth Mountains in 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: Minnesota Glacier: Minnesota Glacier () is a broad glacier, about long and wide, flowing east through the Ellsworth Mountains in Antarctica, separating the Sentinel Range and the Heritage Range. It is nourished by ice from the plateau west of the mountains and by Nimitz Glacier and Splettstoesser Glacier, and merges into the larger Rutford Ice Stream at the eastern margin of the Ellsworth Mountains.
Document 10: 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 11: 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 12: Leonardo Glacier: Leonardo Glacier is a glacier flowing into Wilhelmina Bay between Sadler Point and Café Point, on the west coast of Graham Land, Antarctica. It was charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, and was named by the UK Antarctic Place-Names Committee in 1960 for Leonardo da Vinci, artist, musician, architect and the first aeronautical scientist.
Document 13: 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 14: 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 15: Black Glacier: Black Glacier () is a broad tributary to the Lillie Glacier flowing northeast, marking the southeast extent of the Bowers Mountains, a major mountain range situated in the geographical location of Victoria Land, Antarctica. The glacier was first mapped by the United States Geological Survey from ground surveys and from U.S. Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Robert F. Black, former geologist of the University of Wisconsin, project leader for Antarctic patterned ground studies, who carried out research in the McMurdo Sound region during several summer seasons in the 1960s. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
