'The Khumbu icefall is a passage of constantly-falling ice from the head of the Khumbu glacier, at the point where the ice begins to melt. It is found at around 5,486 metres (17,999ft) above sea level on the Nepalese side of Mount Everest, not far from base camp.
It has been labelled the most dangerous part of the trip up the South Col route to the summit of the mountain.' itv.com
