Polish climber on skis makes Everest descent in first climber to ski down the world's highest mountain

Poland's Andrzej Bargiel has become the first climber to ski down the world's highest mountain without supplemental oxygen, his team and expedition organizer said Thursday. Bargiel glided down Mount Everest's snowy slopes after reaching the summit of the 8,849-metre mountain on Monday.

"He was on top of the highest mountain in the world and he was going to descend it on skis," Bargiel said in a video posted on social media early on Thursday. In 2000, Slovenian Davorin Karnicar made the first full ski descent from Everest's summit to base camp using bottled oxygen. Everest has seen a handful of ski descents but never a continuous downhill without additional oxygen.
