Hard to believe, but the easiest way up the tallest peak in the world starts with a climb through this treacherous icefall. The icefall moves downhill at about one metre per day, which means its seracs and crevasses are constantly rearranging. This makes the Khumbu an extremely dangerous and unpredictable part of the journey up Chomolungma.
