C4 at ice cave under the dablam.

So many teams on mountain at same time that this expedition had tents scattered up and down route and various members slept at various altitudes but not at all tented spots; and Treadwell went ahead of others members and slept in a German tent at C2. Some members skipped some tents/camps and members arrived at different times so they acclimatized at different times; but really were a single expedition.
