Although grateful for the invitation, Mallory initially felt reluctant to accept it, knowing that his participation would mean a lengthy separation from his wife and young children, and he also expressed scepticism regarding the viability of the expedition.{{sfn|Gillman|Gillman|2000|p=171}}{{sfn|Green|2005|p=102}} Geoffrey Winthrop Young visited him at the Holt, Godalming when he learned of his hesitance and swiftly persuaded him and Ruth not to disregard the opportunity, saying that it would be an incredible adventure and earn him reputable renown for prospects in future professions as an educator or writer.{{sfn|Robertson|1999|p=148}}{{sfn|Gillman|Gillman|2000|p=171}} Young's arguments convinced Ruth, and she concurred that Mallory should join the expedition; realising it was "the opportunity of a lifetime," Mallory decided to participate.{{sfn|Green|2005|p=102}} On 9 February 1921, in Mayfair, London, Mallory met with Sir Francis Younghusband, chairman of the Mount Everest Committee; John Percy Farrar, a committee member; and Harold Raeburn, the assigned mountaineering leader of the 1921 British Mount Everest reconnaissance expedition.{{sfn|Gillman|Gillman|2000|pp=171–172}}{{sfn|Green|2005|p=102}} At the meeting, Younghusband formally invited Mallory to join the expedition and was surprised to observe that he accepted without any evident emotion and exhibited no indication that he was brimming with enthusiasm.{{sfn|Gillman|Gillman|2000|p=172}}{{sfn|Green|2005|p=102}} In February 1921, Mallory officially tendered his resignation from his mastership at Charterhouse, changing his previous intended decision of resigning at the end of the summer term.{{sfn|Green|2005|p=102}}

The location of Odell's initial reported final sighting of Mallory and Irvine—before they disappeared into the clouds and was to become the last time the pair were seen alive—was at the top of the Second Step and determined by expedition member John de Vars Hazard using a theodolite to be at an elevation of {{convert|8603.5|m|abbr=on|sigfig=4|order=flip}}.{{sfn|Norton|1925|p=140}}{{sfn|Norton|1924|pp=160–161}}{{refn |Odell was emphatically sure he saw moving figures, not geological objects, and after returning to England, individuals persuaded him that it must have been the First Step where he had last seen them.{{cite web |url=https://www.pbs.org/wgbh/nova/transcripts/26mieverest.html |title=Everest: Mystery of Mallory and Irvine |website=pbs.org |date=6 October 1999 |publisher=PBS |location=Arlington, Virginia, U.S. |access-date=17 August 2022 |url-status=live |archive-url=https://web.archive.org/web/20220817164417/https://www.pbs.org/wgbh/nova/transcripts/26mieverest.html |archive-date=17 August 2022}} He later expressed uncertainty about whether it was the First or Second Step stating, "Owing to the small portion of the summit ridge uncovered, I could not be precisely certain at which of these two "Steps" they were, as in profile and from below they are very similar, but at the time I took it for the upper "Second Step." However, I am a little doubtful now whether the latter would not be hidden by the projecting nearer ground from my position below on the face."{{sfn|Norton|1925|p=130}} Odell also stated, "The "Second Rock Step" is seen prominently in photographs of the North Face from the Base Camp, where it appears a short distance from the base of the final pyramid down the snowy first part of the crest of the Northeast Arête."{{sfn|Norton|1925|p=130}}|group=n|name=lastsighting}} At approximately 2{{nbsp}}pm, as Odell reached Camp VI at {{convert|8138|m|abbr=on|sigfig=4|order=flip}}, snow began to fall, and the wind strengthened.{{sfn|Norton|1925|p=131}} Inside Mallory and Irvine's tent, he discovered spare clothes, food scraps, sleeping bags, oxygen cylinders, and parts of the oxygen apparatus; outside, he found parts of the oxygen apparatus and the duralumin carriers.{{sfn|Norton|1925|p=131}} They left no note specifying when they had commenced their attempt or what might have transpired to create a delay.{{sfn|Norton|1925|p=132}} Odell departed from Camp VI, ascended about {{convert|61|m|abbr=on|sigfig=2|order=flip}} in the direction of the summit in sleet and poor visibility of no more than a few yards, and whistled and yodelled in an attempt to direct Mallory and Irvine towards Camp VI in case they happened to be within hearing distance, but to no avail.{{sfn|Norton|1925|p=132}} Within one hour, he retreated, and at approximately 4{{nbsp}}pm, as he re-attained Camp VI, the weather cleared; the entire North Face became bathed in sunshine, and the upper crags became observable, but there was no sign of Mallory or Irvine.{{sfn|Norton|1925|p=132}} Odell left Mallory's compass, which he had retrieved from Camp V, inside the tent at Camp VI and, at about 4:30{{nbsp}}pm, descended to Camp IV.{{sfn|Norton|1925|p=133}}

On 30 May 1933, during the 1933 British Mount Everest expedition, Percy Wyn-Harris and Lawrence Wager commenced their summit attempt from Camp VI, at {{convert|8380.4|m|abbr=on|sigfig=4|order=flip}}, on the Yellow Band, below the Northeast Ridge.{{sfn|Hemmleb|Simonson|2002|pp=132 & 180}}{{sfn|Ruttledge|1934|pp=135–137}} After approximately one hour of climbing, Wyn-Harris, who was leading, found an ice axe located about {{convert|18|m|abbr=on|sigfig=1|order=flip}} below the crest of the Northeast Ridge and {{convert|229|m|abbr=on|sigfig=3|order=flip}} east of and below the First Step, at an elevation of {{convert|8450|m|abbr=on|sigfig=4|order=flip}}.{{sfn|Hemmleb|Simonson|2002|pp=14, 132, & 190}}{{sfn|Ruttledge|1934|p=137}} Wyn-Harris and Wager left the axe where they had discovered it, and after retreating from a failed summit attempt, Wyn-Harris retrieved the axe and presumably left his own in its place.{{sfn|Hemmleb|Simonson|2002|pp=132–134 & 189}}{{sfn|Ruttledge|1934|pp=138–141}}{{refn |In the spring of 1999, Wyn-Harris's grandson, Steve, informed Jochen Hemmleb in an email exchange that his grandfather had written in his unpublished memoirs that he had returned to Camp VI with both axes.{{sfn|Hemmleb|Simonson|2002|loc=Appendix II, notes and references of chapter 8, no. 8|p=199}}|group=n|name=wyn-harris-ice-axe}}

The axe was ascertained to be either Mallory or Irvine's, to the exclusion of all others.{{sfn|Holzel|Salkeld|1999|p=8}} During his descent with Edward Norton on 4 June 1924, Howard Somervell had dropped his ice axe in the Yellow Band near the Norton Couloir,{{refn|On 4 June 1924, Somervell accidentally dropped his ice axe at an elevation {{circa}} {{convert|8534|m|abbr=on|sigfig=4|order=flip}}, which tumbled down the North Face from a location close to where he took the photo of Norton nearing his high point.{{sfn|Norton|1925|p=114}}|group=n|name=somervell's-axe}} further west from where Wyn-Harris had found the ice axe, and no mountaineers from the expeditions before 1933, other than Mallory and Irvine, had moved through the location where Wyn-Harris had discovered the axe.{{sfn|Norton|1925|p=114}}{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=110}} The axe found by Wyn-Harris was therefore definitively Mallory's or Irvine's, but the men present could not identify it further at the time.{{sfn|Odell|1934|p=447}}

When Wyn-Harris showed the axe to Noel Odell in 1934, Odell noticed three parallel horizontal nick marks on its shaft, something which neither Harris nor Wager had noted before.{{sfn|Odell|1934|p=447}}{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=110}}

Odell thought this to be a mark which Irvine might have used on some of his equipment. Some members of Irvine's family also seemed to remember seeing a similar marking, although this could not be verified by visual inspection of items which had been returned to Irvine's family.{{sfn|Odell|1934|p=447}}

Mallory's widow Ruth informed Odell that, "as far as she was aware"—which may indicate she was unsure—Mallory never marked his equipment with triple marks or other type of mark, and assumed the axe belonged to Irvine.{{sfn|Odell|1934|p=447}} To Odell, Wyn Harris suggested a porter may have cut the triple mark to identify individuals' property during the 1924 expedition, though such was not the practice of many, if any, of the 1924 porters.{{sfn|Odell|1934|p=447}} Wyn Harris assured Odell that his porter Pugla cut the X mark, seen lower down on the shaft of the axe found in 1933, during the return journey from the 1933 expedition.{{sfn|Odell|1934|p=447}} Several 1933 expedition members considered it likely the axe belonged to Mallory because it had a Swiss manufacturer, Willisch of Täsch, stamped on it, and Mallory had journeyed to the Alps shortly before the 1924 expedition, when he may have acquired it.{{sfn|Odell|1934|p=447}} They were unaware this manufacturer had supplied all members of the 1924 expedition with light axes, and Mallory or Irvine might have used them during their fatal summit attempt.{{sfn|Odell|1934|p=447}}

In 1962, a brother of Irvine found a military swagger stick, presumed to have belonged to Irvine, and on it are three horizontal identification nick marks resembling those on the axe discovered by Wyn-Harris in 1933; therefore, the axe is most likely Irvine's.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=110}}{{sfn|Hemmleb|Simonson|2002|p=134}}

In 1977, Walt Unsworth, author of Everest: The Ultimate Book of the Ultimate Mountain, examined the axe discovered in 1933 and observed four sets of marks on its shaft.{{sfn|Unsworth|1991|loc=Appendix VI, notes and references of chapter 5, no. 36|p=655}} In addition to the three nicks seen by Odell and the cross mark cut by Pugla, he saw a single horizontal nick mark above the three observed by Odell and another three nick marks, though fainter in appearance, on the other side of the shaft opposite the cross mark.{{sfn|Unsworth|1991|loc=Appendix VI, notes and references of chapter 5, no. 36|p=655}}

Everest historian, Tom Holzel, the co-author with Audrey Salkeld of The Mystery of Mallory and Irvine, first became interested in the Mallory and Irvine enigma after reading about it in a 1970 edition of The New Yorker.{{sfn|Holzel|Salkeld|1999|p=4}} Holzel devised a theory regarding the mystery, published in a 1971 edition of Mountain magazine.{{sfn|Holzel|Salkeld|1999|pp=10, 322, & 360 notes on sources of chapter 1, no. 11}} His theory was that the two mountaineers split up soon after Odell had sighted them ascending the Second Step at 12:50{{nbsp}}pm, and when successfully climbed, each had only {{frac|1|1|2}} hours of supplemental oxygen remaining, insufficient for both to reach the summit in two or three hours.{{sfn|Holzel|Salkeld|1999|p=322}} Holzel argued that given this dilemma, Mallory took Irvine's oxygen equipment, belayed him down the Second Step, from where he descended towards Camp VI at {{convert|8138|m|abbr=on|sigfig=4|order=flip}}, and with the additional oxygen, Mallory attempted to reach the summit alone.{{sfn|Holzel|Salkeld|1999|p=323}} He further surmised that as the exhausted Irvine descended, the "rather severe blizzard" described by Odell,{{sfn|Odell|1924|p=458}} which lasted from approximately 2 to 4pm,{{sfn|Norton|1925|pp=131–132}} covered the mountain with snow, turned his descent into a deadly endeavour, and caused him to slip and fall to his death.{{sfn|Holzel|Salkeld|1999|p=323}}{{cite news |editor-last=Hoelzgen |editor-first=Joachim |date=29 June 1986 |title=Das phantastischste Rätsel des Jahrhunderts |trans-title=The most fantastic riddle of the century |url=https://www.spiegel.de/politik/das-phantastischste-raetsel-des-jahrhunderts-a-ba2a9318-0002-0001-0000-000013520180 |url-status=live |work=Der Spiegel |language=German |location=Hamburg, Germany |publisher=SPIEGEL-Verlag Rudolf Augstein GmbH & Co.

After he had re-examined the historical record of Everest North Face expeditions, Jochen Hemmleb recognised the only seemingly factual information about Mallory and Irvine—other than artefacts such as the ice axe, found in 1933—was that during the 1975 Chinese Everest expedition, Wang Hongbao had discovered a body he had insisted was "English, English!" during a twenty-minute walk from Camp VI.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=111}} The initial challenge was to identify the location of Chinese Camp VI and use it as the centre point of a circular search zone with a twenty-minute walk radius.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=112}}{{sfn|Anker|Roberts|1999|p=31}} From a photo of Camp VI, Hemmleb determined it was on an ill-defined rib of rock that bisects the snow terrace on the North Face.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=112}}

On 1 May 1999, at approximately 10am, Anker, Hahn, Norton, Politz, and Richards reached {{convert|8199|m|abbr=on|sigfig=3|order=flip}}, where they were to establish Camp VI.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|pp=113–116 & 196–197}} From there, they set out for the "ill-defined rib" and traversed west over the North Face's precipitously angled terrain.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=116}}{{sfn|Anker|Roberts|1999|p=31}} Anker searched on intuition and descended to the lower margin of the snow terrace, where it drops away approximately {{convert|2000|m|abbr=on|sigfig=3|order=flip}} to the head of the central Rongbuk Glacier and soon after zig-zagging back up in the direction of Camp VI, he looked west and saw a "patch of white," which he proceeded towards, and ascertained it was an old body; it was 11:45{{nbsp}}am, and {{convert|8156|m|abbr=on|sigfig=3|order=flip}} was the elevation where the corpse lay.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|pp=119–197}}{{sfn|Hemmleb|Simonson|2002|p=180}}{{cite web |url=https://www.mountainzone.com/everest/99/north/disp5-3conrad.html |title=Daily Dispatches A Patch of White |last=Anker |first=Conrad |author-link=Conrad Anker |date=3 May 1999 |website=MountainZone |publisher=Locality LLC |location=U.S. |access-date=16 April 2023 |url-status=live |archive-url=https://web.archive.org/web/20230416163449/https://www.mountainzone.com/everest/99/north/disp5-3conrad.html |archive-date=16 April 2023}} The body was partially frozen into the scree and well preserved due to the cold, dry air and constant freezing temperatures.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|pp=120–122}}{{sfn|Anker|Roberts|1999|p=34}}{{cite news |author= |date=3 May 1999 |title=Mallory's Son Says Everest Mystery Still Unsolved |url=https://www.chicagotribune.com/news/ct-xpm-1999-05-03-9905040145-story.html |url-status=live |work=Chicago Tribune |location=Chicago, Illinois, U.S. |publisher=Tribune Publishing |archive-url=https://web.archive.org/web/20210419034425/https://www.chicagotribune.com/news/ct-xpm-1999-05-03-9905040145-story.html |archive-date=19 April 2021 |access-date=17 April 2023}} Tied to the corpse's waist were the remnants of a braided cotton climbing rope, tangled around the body, from which its broken, frayed end trailed.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|p=125}}{{sfn|Anker|Roberts|1999|p=21}}

The prevalent assumption was Irvine had fallen in 1924 from where, in 1933, Percy Wyn-Harris had discovered the ice axe, presumably Irvine's; therefore, Anker, Hahn, Norton, and Richards expected the body to be his, but Politz said, "This is not him."{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|pp=118 & 121–123}}{{refn |The reason for Politz's scepticism regarding the body being Irvine's was its position; within his subconscious, his intuition had remembered that Wang Hongbao had discovered a corpse in a position with its mouth agape and one cheek pecked at by goraks, this body was lying prone.{{sfn|Hemmleb|Johnson|Simonson|Nothdurft|1999|pp=121–123}}|group=n|name=mouth-agape}} Norton found a label reading, "G.

The discovery of the body revealed circumstantial evidence that suggests Mallory might have reached the summit: firstly, Mallory's daughter always said Mallory carried a photo of his wife with the intention of leaving it on the summit,{{Cite web|url=https://www.thetimes.com/article/body-may-prove-who-was-first-up-everest-mfj8bdzlk8l|title=Body may prove who was first up Everest|first=Nicholas|last=Hellen|date=9 August 2024|website=www.thetimes.com}} and no such photo was found on the body. Given the excellent preservation of the body and personal possessions, the absence of the photo suggests he may have reached the summit and deposited it there. Secondly, Mallory's snow goggles were in his pocket, indicating he may have died at night; that he and Irvine had made a push for the summit and were descending very late in the day. Given their known departure time and movements, had they not made the summit, it is unlikely they would have still been out by nightfall.

Sir Edmund Hillary enthusiastically welcomed the discovery of Mallory's body and described it as "very appropriate" that Mallory might have summited decades earlier. "He was really the initial pioneer of the whole idea of climbing Mount Everest," Hillary said. Mallory's son John said, "To me the only way you achieve a summit is to come back alive; the job's half done if you don't get down again."{{cite news |last=Gentleman |first=Amelia |author-link=Amelia Gentleman |date=4 May 1999 |title=Irvine and Mallory: In hobnail boots they took on Everest |url=https://www.theguardian.com/uk/1999/may/04/ameliagentleman |url-status=live |work=The Guardian |publisher=Guardian News & Media |location=London, UK |archive-url=https://web.archive.org/web/20220812193434/https://www.theguardian.com/uk/1999/may/04/ameliagentleman |archive-date=12 August 2022 |access-date=12 August 2022}}

Mallory and Irvine inspired Baku Yumemakura to author the 1998 novel The Summit of the Gods, which in turn inspired a manga series published from 2000–03, which was adapted into an anime-influenced animation film, Le Sommet des Dieux, in 2021.
