The 1996 Everest Disaster: What Happened, and What Changed

On 10–11 May 1996, a storm caught climbers high on Mount Everest and eight people died — among them two of the most respected commercial expedition leaders in the world. It became the most written-about day in the mountain’s history, largely through Jon Krakauer’s Into Thin Air, and it changed how guided climbing is run. Thirty years on, it is worth recounting what happened plainly, and with respect for the people who did not come home.

What happened

Two commercial teams went for the summit on 10 May: Adventure Consultants, led by New Zealander Rob Hall, and Mountain Madness, led by the American Scott Fischer. Both were experienced, professional outfits. Several things then went wrong at once. Fixed ropes were not in place at key points, creating long queues at the Hillary Step and the Balcony. Many climbers summited far later than the unwritten early-afternoon turnaround, some not reaching the top until after 2–4 pm, which left them descending exhausted into the coldest, darkest part of the day.

Then the weather broke. A blizzard swept the upper mountain in the afternoon, dropping visibility to nothing and the temperature far below survivable limits. Climbers were stranded on the South Col and along the summit ridge in a whiteout, unable to find camp. Rob Hall stayed high with his client Doug Hansen and could not get down; his final radio calls, patched through to his wife in New Zealand, are among the most quietly devastating records in mountaineering. Scott Fischer, descending late and severely weakened, died near the Balcony. On the Tibetan north side the same storm killed three climbers of the Indo-Tibetan Border Police, a loss long overshadowed by the events on the south.

The lessons that changed guided climbing

The disaster forced the guiding industry to confront how it managed clients at altitude, and much of today’s standard practice traces back to it. Hard turnaround times — a fixed hour after which you go down whether or not you have summited — became non-negotiable on serious operations. Teams now insist on fixed ropes being set in advance by dedicated rope-fixing teams, so bottlenecks do not strand people in the open. Oxygen logistics are planned in far greater depth, with reserves cached for the descent. Weather forecasting improved enormously; expeditions now buy specialist mountain forecasts rather than reading the sky. And radios and, later, satellite communication became universal.

The event also opened a hard, still-unfinished debate about commercial climbing itself — whether paying clients belong in the death zone at all, how much a guide can be expected to do for a struggling client, and where the line sits between ambition and responsibility. Krakauer’s account and the counter-account by Fischer’s lead guide Anatoli Boukreev, The Climb, disagreed sharply, and the argument shaped a generation of climbers. What is not in dispute is that Everest’s margins are thin and unforgiving, a truth confirmed by the deadliest avalanches in the Nepal Himalaya and by every serious season since.

You can meet Everest without entering the death zone

Almost everyone who loves this mountain sees it from below, on foot, and comes home. The trek to Everest Base Camp stops at 5,364 m — high enough to feel the altitude, well below the zone where 1996 unfolded — and it is where the great majority of Everest stories, ours included, actually begin.
