A team led by National Geographic recently discovered a foot encased in a sock and boot on the Central Rongbuk Glacier of Mount Everest, believed to belong to Andrew 'Sandy' Irvine, who vanished in 1924 during an expedition with George Mallory. The sock is embroidered with 'AC Irvine', marking a significant finding in the ongoing mystery surrounding their fate, as they were last seen approximately 800 feet from the summit. While Mallory's remains were found in 1999, Irvine's body had never been located, and this discovery serves as the first potential evidence of his death. The search for Irvine's remains has been motivated by hopes of finding a Kodak camera he carried, which might provide proof of whether they reached the summit before Hillary and Norgay in 1953. The foot will undergo DNA testing to confirm its identity, and the finds have been reported to the Royal Geographical Society. The team expressed hope that this discovery will bring closure to Irvine's family and the climbing community.
