Summary
This timeline sets the ice-wall story against the dates it rests on. It opens in January 1841, when James Clark Ross came upon the cliff he named the Great Ice Barrier, today's Ross Ice Shelf. In 1849 Samuel Rowbotham, writing as "Parallax", published the pamphlet that describes a flat Earth bounded by ice, and in 1892 Alexander Gleason issued his North Pole-centred map subtitled "As it is". The following decades fill the record with real expeditions. Amundsen reached the South Pole from the Great Ice Barrier on 14 December 1911, and Scott on 17 January 1912, dying on the way back. In 1946–1947 Operation Highjump sent 4,700 US Navy men, 13 ships and 33 aircraft under Admiral Byrd and set up Little America IV on the Ross Ice Shelf. On 5 March 1947 El Mercurio published the Byrd interview that some sites now link, without a source, to the "land beyond the Pole" quote.
On 1 December 1959 twelve countries signed the Antarctic Treaty in Washington, reserving the continent for peace and science; it came into force on 23 June 1961. Qantas and Air New Zealand began flying passengers over Antarctica in February 1977. The online revival appears in 2015 with Mark Sargent's YouTube series Flat Earth Clues. The timeline closes in December 2024 with "The Final Experiment", when flat-Earth and globe YouTubers filmed the midnight sun at Union Glacier and the flat-Earthers admitted it was real.
