In May 1996 three expeditions attempted to climb Mount Everest on the Southeast Ridge route pioneered by Sir Edmund Hillary and Tenzing Norgay in 1953. Crowded conditions slowed their progress. Late in the day twenty-three men and women-including expedition leaders Scott Fischer and Rob Hall-were caught in a ferocious blizzard. Disoriented and out of oxygen, climbers struggled to find their way down the mountain as darkness approached. Alone and climbing blind, Anatoli Boukreev brought climbers back from the edge of certain death. This new edition includes a transcript of the Mountain Madness expedition debriefing recorded five days after the tragedy, as well as G. Weston DeWalt"s response to Into Thin Air author Jon Krakauer.
