Polish mountaineer Andrzej Bargiel has achieved a historic first: skiing down Mount Everest without supplemental oxygen. He reached the summit on Monday and skied to Camp 2, spending a night before reaching base camp the next day. This feat, described as 'extremely challenging' by expedition organizers, involved navigating heavy snowfall and spending 16 hours in the 'death zone'. Bargiel's accomplishment marks a groundbreaking milestone in ski mountaineering, following his previous successful descents of K2 and other high-altitude peaks.
