Question: How big is the continent where the McKellar Glacier is found?

full_context: Document 1: McKinnon Glacier: The McKinnon Glacier () is a glacier flowing southeast from Nemesis Glacier to Beaver Lake in the eastern part of the Aramis Range of the Prince Charles Mountains in Antarctica. The area was first visited by an Australian National Antarctic Research Expeditions (ANARE) party in 1956 and mapped from ANARE air photographs. The glacier was named by the Antarctic Names Committee of Australia for Graeme W. McKinnon, Geographical Officer with the Antarctic Division, Melbourne, and Officer in Charge of the ANARE Prince Charles Mountains survey party in 1969.
Document 2: 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 3: Carryer Glacier: Carryer Glacier is a heavily crevassed tributary glacier, long, which drains westward from the central part of the Bowers Mountains and enters Rennick Glacier between Mount Soza and Mount Gow, Victoria Land, Antarctica. The glacier was named by the northern party of New Zealand Geological Survey Antarctic Expedition, 1963–64, for S.J. Carryer, former geologist with this party. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 4: Ball Glacier (Victoria Land): Ball Glacier is a glacier long with the head located between Mount Lister and Mount Hooker on the east side of the Royal Society Range. The glacier flows northeast between Craw Ridge and Tasman Ridge into Blue Glacier. It was named by the New Zealand Geographic Board after Gary Ball, a New Zealand mountaineer who climbed Mount Lister with an Italian field party, 1976–77, and camped on this glacier; he was field assistant with R.H. Findlay’s New Zealand Antarctic Research Program party to this area, 1980–81.
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: McKellar Glacier: McKellar Glacier is a tributary glacier flowing south along the east side of Evans Ridge into Pearl Harbor Glacier in the Victory Mountains of Victoria Land, Antarctica. It was named by the northern party of the New Zealand Federated Mountain Clubs Antarctic Expedition (NZFMCAE), 1962–63, for I.C. McKellar, geologist and glaciologist to the New Zealand Geological Survey Antarctic Expedition, 1957–58, which undertook surveys in the nearby Tucker Glacier area.
Document 7: Kelly Glacier: Kelly Glacier () is a steep tributary glacier descending southwest from Mount Peacock to enter Tucker Glacier just south of Mount Titus, in the Admiralty Mountains of Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Lieutenant Anthony J. Kelly, U.S. Navy, medical officer at Hallett Station, 1961.
Document 8: Antarctica: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
Document 9: McLean Glacier: McLean Glacier () is a tributary glacier located north of Mount Hemphill in the southwest part of the Anare Mountains, Antarctica, draining west and entering the lower part of Ebbe Glacier just south of Beaman Glacier. It was named by the Advisory Committee on Antarctic Names for Kenneth S. McLean, a topographic engineer with the United States Geological Survey Topo East–West party that surveyed this area in the 1962–63 season.
Document 10: George Glacier: George Glacier is a valley glacier in the western part of the Anare Mountains of Victoria Land, Antarctica. The glacier rises east of Mount Burch and flows northwest past Mount Kelly to Lillie Glacier Tongue on the coast. This geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–1965, and was named by the Advisory Committee on Antarctic Names for Robert Y. George, a zoologist at McMurdo Station, Hut Point Peninsula, Ross Island, 1967–1968. The glacier is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 11: Ice sheet: The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million km and contains 30 million km of ice. Around 90% of the Earth's ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters. The continent - wide average surface temperature trend of Antarctica is positive and significant at > 0.05 ° C / decade since 1957.
Document 12: 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.
Document 13: 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 14: 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 15: 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.
