A small team led by National Geographic Explorer, photographer, Academy Award winning director, and professional climber Jimmy Chin discovered a sock embroidered with ‘A.C. Irvine’, along with a boot, on the Central Rongbuk Glacier below the North Face of Everest, September 2024. This is the first possible proof of Irvine's death since disappearing during a 1924 expedition.
