Khumbu Icefall, Nepal, 1999

Photo: Khumbu Icefall

Heading for camp one, climber Chris Binggeli negotiates a crevasse in Mount Everest's Khumbu Icefall.

Says the photographer: "It's terrifying to shoot on the icefall. The glacier is constantly shifting underneath. You just have to keep moving or you risk being squashed."
