On the 29th, Hall's team (minus Hansen) makes another attempt at Camp Three. Though the going is agonizingly painful, Krakauer successfully makes it.
Along the way, he finds himself impressed by his inexperienced colleagues, namely Beck Weathers. Although the two men's political differences drove a wedge between them at first, Krakauer finds himself respecting Weather's fearless pursuit of his goals.
Unlike Camps One and Two, Camp Three is precariously perched on the side of the mountain. In other words, "the vista was primarily sky rather than earth" (10.18).
Despite his pride, Krakauer is a little freaked out—he worries that he has High Altitude Cerebral Edema (HACE), which is when one's brain is deprived of oxygen and begins swelling painfully.
Hall's posse descends back to Base Camp over the next several days. This is a momentous occasion, as it marks the final acclimatization trip—they'll be heading for the summit on May 10.
Fischer's team will be attempting the summit the same day, and the other teams are supposed to make their own attempts on the days before and after.
