Edward Michael "Bear" Grylls

To prepare for climbing at such high altitudes in the Himalayas, in 1997, Grylls became the youngest Briton to climb Ama Dablam, a peak described by Sir Edmund Hillary as "unclimbable". Grylls' Everest expedition involved nearly four months on the mountain's southeast face. On his first reconnaissance climb he fell into a deep crevasse and was knocked unconscious. The following weeks of acclimatisation involved climbs up and down the south face, negotiating the Khumbu Icefall (a frozen river), the Western Cwm glacier, and a 1,500-metre (5,000 ft) wall of ice called the Lhotse face, before he made the ascent with the ex-SAS soldier Neil Laughton.
