Question: What is the surface area in square miles of the continent containing Gorki Ridge?

full_context: Document 1: Mount Korsch: Mount Korsch () is a pyramidal peak, rising to about on the northwest margin of Markham Plateau, Queen Elizabeth Range, Antarctica, west of Mount Markham. It was named by the Advisory Committee on Antarctic Names in 1988 after geologist Russell J. Korsch who, with E. Stump and D. Egerton, climbed and geologically mapped this peak on December 3, 1985, as a member of a United States Antarctic Research Program (USARP) field party. Korsch was a member of USARP field parties, 1968–69 and 1985–86, and of New Zealand Antarctic Research Program field parties, 1982–83 and 1984–85.
Document 2: Southern Ocean: The Southern Ocean, geologically the youngest of the oceans, was formed when Antarctica and South America moved apart, opening the Drake Passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar Current.
Document 3: Antarctica: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Document 4: Mechnikov Peak: Mechnikov Peak () is a prominent peak, high, at the base of the spur separating Schussel Cirque and Grautskåla 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 was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60. The peak was remapped by the Soviet Antarctic Expedition, 1960–61, and named after Russian geographer L.I. Mechnikov, 1838–88.
Document 5: Antarctica: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
Document 6: Grautskåla Cirque: Grautskåla Cirque () is a cirque immediately north of The Altar in the Humboldt Mountains of Queen Maud Land, Antarctica. It was discovered and mapped from air photos by the Third German Antarctic Expedition, 1938–39. It was remapped by the Sixth Norwegian Antarctic Expedition, 1956–60, and named Grautskåla (the mash bowl) because of its appearance and association with nearby Schussel Cirque. It is a very cold place. ANTARCTICA!
Document 7: 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.
Document 8: 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 9: 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 10: Antarctica: Antarctica (US English i/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Document 11: Antarctica: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Document 12: Antarctic Plate: The Antarctic Plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Somali Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
Document 13: 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 14: Mount Kibal'chich: Mount Kibal'chich () is the highest peak, high, of the Kvaevenutane Peaks, in the Payer Mountains of Queen Maud Land, Antarctica. It was discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, and was 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 the Russian revolutionary Nikolai Kibalchich.
