The partial remains of British mountaineer Andrew 'Sandy' Irvine, who vanished in 1924 during an attempt to summit Mount Everest with George Mallory, have been discovered by a National Geographic documentary team on the Central Rongbuk Glacier. A sock and boot found with 'A.C. Irvine' stitched into the sock suggest the remains might belong to Irvine, although DNA verification is pending. This discovery could provide insights into whether Irvine and Mallory reached the peak before their deaths, a mystery that has intrigued historians for nearly a century. The remains, now with the China Tibet Mountaineering Association, were found at a lower altitude than where Mallory's body was discovered in 1999. Irvine was reportedly carrying a camera, which has not been found, that might hold evidence of the climbers' potential summit success. The discovery has deeply moved Irvine's family and promises to bring some closure to their long-standing mystery.
