Dave Hahn, a local of Taos, New Mexico, is a legendary figure in mountaineering. Elite members of the climbing community have likened him to the Michael Jordan, Cal Ripkin, or Michael Phelps of the climbing world, while emphasizing the distinction that Dave had accomplished his mountaineering feats while safely guiding non-professional clients. The 2015 expedition that he would lead on Everest came just one short year after a season ending tragedy, when an avalanche in the notorious Khumbu Icefall claimed the lives of sixteen Sherpas working in it. Dave and his team – Sherpa sirdar Chhering Dorje, assistant guide JJ Justman, base camp manager Mark Tucker, and the clients who had trained years for the privilege of climbing with Dave — spent weeks at Base Camp waiting out storms and honing the techniques that would keep them alive through the Icefall and the Death Zone. None of this could have prepared them for the earthquake that shook Everest and all their lives on the morning of April 25, 2015. Shook tells their story of resilience, nerve, and survival on the deadliest day in Everest’s history.
