camps or bivouacked somewhere higher up on Everest, so his failure to return to camp did not initially cause serious concern. High-altitude bivouacs are very risky but are sometimes recommended in certain extreme situations. Sharp ultimately died under the rocky overhang, sitting with arms clasped around his legs, next to Green Boots. The "cave" is situated approximately above the high camps, commonly called Camp 4 but the extreme cold, fatigue, lack of oxygen and darkness made a descent to Camp 4 very dangerous or next to impossible. Accounts of the Fatal Climb Himex Expedition – First Team Himex organised several teams to climb Everest during the 2006 climbing season expedition. The first team was guided by mountain climber and guide Bill Crouse. At around 01:00 on May 14, Crouse's expedition team passed by Sharp during their ascent near the location on the North route known as the "Exit Cracks". When Crouse's team descended around 11:00, they saw Sharp once again but this time he was higher up on the mountain at the base of the Third Step. By the time Crouse's expedition had descended to the Second Step, more than one hour later, they looked back to see that Sharp was above the Third Step but was climbing very slowly and had only moved about . Turkish Team Another source of information about Sharp were reports from a team of Turkish climbers. They left their high camp in the evening on May 14 and were essentially traveling in three separate groups. Late in the evening to early morning, the Turkish team members encountered Sharp in the darkness while they were ascending. The first group encountered Sharp around midnight, noticed he was alive and thought that he appeared to be a climber taking a short break. Sharp supposedly waved them on. Some time later, others who noticed Sharp thought he was already dead; recovery of a dead climber's body is almost impossible due to the conditions so far up the mountain. It is thought that Sharp might have fallen asleep between these two encounters. The fact that Sharp wanted to sleep was noted by other climbers who encountered him later on, and a quote attributed to him telling people that he wanted to sleep was later reported in some news media stories. Some of the Turkish team summited early in the morning on May 15 while some turned back near the
