Question: How many square miles is the continent on which Mount Hampson is located?

full_context: Document 1: 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 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: Edwards Islands (Enderby Land): The Edwards Islands are a group of islands in the east side of Amundsen Bay, about southwest of Mount Oldfield in Enderby Land. They were plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1956, and were named by the Antarctic Names Committee of Australia for T. Edwards, an assistant diesel mechanic at Wilkes Station in 1960.
Document 4: 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 5: 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 6: 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 7: Mount Betty: Mount Betty is a small ridge overlooking the Ross Ice Shelf, on the north side of Bigend Saddle, at the north-eastern extremity of the Herbert Range in the Queen Maud Mountains of Antarctica. It was discovered in November 1911 by Captain Roald Amundsen, and named by him for Betty Andersson, nurse and housekeeper in the Amundsen family for many years.
Document 8: Hammond Glacier: Hammond Glacier is located on the northeast side of the Haines Mountains, flowing northwest for about to Sulzberger Ice Shelf in the Ford Ranges of Marie Byrd Land, Antarctica. It was discovered in 1934 by the Byrd Antarctic Expedition, and named by Richard E. Byrd for John Hays Hammond, an American mining engineer and philanthropist.
Document 9: 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 10: Mount Hampson: Mount Hampson is a mountain north of Mount Rhodes, in the northern part of the Tula Mountains in Enderby Land, Antarctica. It was plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1956, and was named by the Antarctic Names Committee of Australia for R.V. Hampson, a member of the crew of the "Discovery" during the British Australian New Zealand Antarctic Research Expedition of 1929–31.
Document 11: 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 12: Mount Handsley: Mount Handsley () is a subsidiary rock peak on the Knobhead massif in Victoria Land, Antarctica. It rises south-southeast of Knobhead and overlooks the upper part of Ferrar Glacier from the northwest. It was named in 1969 by the New Zealand Antarctic Place-Names Committee after Jesse Handsley, a member of the "Discovery" crew of Captain Robert Falcon Scott's expedition, who accompanied Scott, Evans, Feather, Skelton and Lashly on the major sledging journey up the Ferrar and Taylor Glaciers in 1903.
Document 13: Kyle Nunataks: The Kyle Nunataks () are three nunataks east of Mount Hampson, in the northern part of the Tula Mountains in Enderby Land, Antarctica. They were plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1956, and were named by the Antarctic Names Committee of Australia for J.T. Kyle, a member of the crew of the "Discovery" during the British Australian New Zealand Antarctic Research Expedition, 1929–31.
Document 14: Mount Henson: Mount Henson () is an ice free summit, high, standing at the northeastern extremity of the Mayer Crags, forming the northwest portal to Liv Glacier where the latter enters the Ross Ice Shelf, Antarctica. It was discovered and photographed by the Byrd Antarctic Expedition in November 1929, and named for Matthew Henson, a member of Rear Admiral Robert Peary's party which reached the North Pole in 1909.
Document 15: 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:
