The partial remains of British mountaineer Andrew 'Sandy' Irvine, believed to have vanished while attempting to summit Mount Everest in 1924, have been discovered by a National Geographic expedition led by explorer Jimmy Chin. The team found a foot encased in a sock embroidered with 'A.C. Irvine' and a boot on the Central Rongbuk Glacier, below the North Face of Everest. Irvine and his climbing partner George Mallory disappeared just 800 feet from the summit, and their fate has intrigued climbers and historians for nearly a century. Mallory's body was found in 1999, but there has been no evidence until now to confirm whether they reached the summit before perishing. The discovery raises hopes that Irvine's camera, which could provide photographic proof of their ascent, may still be nearby. The family is considering DNA testing to confirm the identity of the remains, with Chin expressing hope that this find will bring closure to the climbing community and Irvine's relatives.
