Question: What latitude is defined as being the border of the continent on which Fenristunga is located?

full_context: Document 1: Antarctica: In 1983, the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. A coalition of international organizations launched a public pressure campaign to prevent any minerals development in the region, led largely by Greenpeace International, which established its own scientific station—World Park Base—in the Ross Sea region and conducted annual expeditions to document environmental effects of humans on Antarctica. In 1988, the Convention on the Regulation of Antarctic Mineral Resources (CRAMRA) was adopted. The following year, however, Australia and France announced that they would not ratify the convention, rendering it dead for all intents and purposes. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. The Protocol on Environmental Protection to the Antarctic Treaty (the "Madrid Protocol") was negotiated as other countries followed suit and on 14 January 1998 it entered into force. The Madrid Protocol bans all mining in Antarctica, designating Antarctica a "natural reserve devoted to peace and science".
Document 2: Borg Massif: Borg Massif is a mountain massif, about long and with summits above , situated along the northwest side of the Penck Trough in Queen Maud Land, East Antarctica. The tallest peak, at , is Hogsaetet Mountain. The parallel, ice-filled Raudberg Valley and Frostlendet Valley trend northeastward through the massif, dividing its summits into three rough groups:
Document 3: Fenristunga: Fenristunga () is a sloping field of ice within the rock walls of hairpin-shaped Fenriskjeften Mountain, in the Drygalski Mountains of Queen Maud Land, Antarctica. It was mapped from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Fenristunga (Fenrir's tongue) in association with Fenriskjeften Mountain.
Document 4: National Antarctic Program: Till date 48 countries have signed the Antarctic Treaty which was drafted and negotiated back in 1959. Out of these, only 28 countries have the Consultative status i.e. these Parties have the right to participate in Antarctic Treaty Consultative Meetings (ATCM) and are accordingly known as Consultative Parties and their presence in Antarctica is shown by carrying substantial research there.
Document 5: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
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: Håhellerskarvet: Håhellerskarvet, meaning "shark cave mountain" in Norwegian, is a high partially ice-covered mountain between Austreskorve Glacier and Lunde Glacier in the Mühlig-Hofmann Mountains of Queen Maud Land, East Antarctica. Other nearby geographic features include Håhelleren Cove, indenting the north side of Håhellerskarvet, Håhelleregga Ridge, an irregular rock ridge just north of Håhellerskarvet, Håhellerbotnen Cirque, a large cirque on the east side of Håhelleregga Ridge, and Jøkulkyrkja, a broad, ice-topped mountain located east of Lunde Glacier. All of these geographic features were plotted from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60).
Document 8: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 9: Kiletangen Ice Tongue: Kiletangen Ice Tongue () is a narrow projection of the ice shelf on the east side of Tangekilen Bay, along the coast of Queen Maud Land, Antarctica. It was first mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and named Kiletangen (the bay tongue).
Document 10: Antarctica: The Protocol on Environmental Protection to the Antarctic Treaty (also known as the Environmental Protocol or Madrid Protocol) came into force in 1998, and is the main instrument concerned with conservation and management of biodiversity in Antarctica. The Antarctic Treaty Consultative Meeting is advised on environmental and conservation issues in Antarctica by the Committee for Environmental Protection. A major concern within this committee is the risk to Antarctica from unintentional introduction of non-native species from outside the region.
Document 11: Festninga Mountain: Festninga Mountain is a broad, ice-topped mountain, high, standing west of Mount Hochlin at the west end of the Mühlig-Hofmann Mountains, in Queen Maud Land, Antarctica. it was mapped by Norwegian cartographers from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Festninga (the fortress). Austvollen Bluff forms the east side of the mountain.
Document 12: Flensing Icefall: Flensing Icefall is a large icefall at the east side of the Bowers Mountains in Victoria Land, Antarctica, situated south of Platypus Ridge at the junction of Graveson Glacier and Rastorguev Glacier with Lillie Glacier. The icefall was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, because the icefall's longitudinal system of parallel crevassing resembles the carcass of a whale when being flensed. This glaciological feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 13: Australian Antarctic Data Centre: Article III.1.c of the Antarctic Treaty states that "to the greatest extent feasible and practicable" ... "scientific observations and results from Antarctica shall be exchanged and made freely available"
Document 14: Mount Kropotkin: Mount Kropotkin is a peak on the west side of Jøkulkyrkja Mountain in the Mühlig-Hofmann Mountains of Queen Maud Land, Antarctica. It was mapped by the Norsk Polarinstitutt from surveys and air photos by the Sixth Norwegian Antarctic Expedition, 1956–60. The peak was also mapped by the Soviet Antarctic Expedition in 1961 and named for Russian anarchist Peter Kropotkin.
Document 15: Fenrir Valley: Fenrir Valley () is a small, mainly ice-free valley between the upper reaches of Heimdall Glacier and Rhone Glacier in the Asgard Range of Victoria Land, Antarctica. The name, applied by the New Zealand Antarctic Place-Names Committee and the Advisory Committee on Antarctic Names in consultation, is one in a group in the range derived from Norse mythology, wherein Fenrir is a wolf chained by Tīw.
