Summary

On 10–11 May 1996, a storm caught several commercial expeditions high on the southeast side of Mount Everest as they descended from the summit, and eight climbers died — the deadliest single day the mountain had then known. Among the dead were the two expedition leaders, the New Zealand guide Rob Hall of Adventure Consultants and the American guide Scott Fischer of Mountain Madness, both of whom perished above 8,000 metres after staying too long on the mountain. The season's total toll reached twelve, then the largest in Everest's history.

The two flagship guided teams had left the highest camp on the South Col, at roughly 8,000 metres, near midnight on 10 May, climbing the standard southeast ridge route from the Nepalese side. Both leaders had spoken of a firm turnaround time — a deadline, around 1 or 2 p.m., past which a climber short of the summit must turn back to descend in daylight. That discipline broke down. Ropes that should have been fixed in advance at the Balcony and the Hillary Step were not, creating long queues at the route's bottlenecks, and clients reached the summit dangerously late in the afternoon, some after 2 p.m. and several near or after 4 p.m. As they started down, a blizzard with winds reported above 100 km/h closed over the upper mountain and erased the route.

The disaster became the most scrutinized event in mountaineering history, in large part because the journalist Jon Krakauer was a client on Hall's team and wrote the bestselling account Into Thin Air; the Russian-Kazakh guide Anatoli Boukreev, a guide on Fischer's team who carried out a remarkable solo rescue on the South Col, answered Krakauer's criticisms in his own book, The Climb. The episode reshaped the public debate over the commercialization of Everest. It also depended, as every Everest climb does, on Sherpa labour: Ang Dorje Sherpa and Lopsang Jangbu Sherpa led the climbing support, broke trail, and were drawn into the rescue, work that this record places at the centre rather than the margin of the story.

Timeline

Spring 1996
A crowded season
Multiple commercial and national expeditions converge on the south side; Adventure Consultants (Rob Hall) and Mountain Madness (Scott Fischer) are the principal guided teams.
9 May 1996
Move to the South Col
The teams ascend to Camp IV on the South Col at about 8,000 m, resting before a midnight start for the summit.
~Midnight, 10 May
The summit push begins
Hall's and Fischer's clients and guides leave Camp IV for the southeast ridge in the dark.
Morning, 10 May
Bottlenecks
Fixed ropes are not in place at the Balcony and the Hillary Step; climbers wait, losing hours, while guides install them.
~1:00 p.m., 10 May
First on top
Boukreev reaches the summit; other clients arrive through the early afternoon, many past the agreed turnaround time.
~3:45 p.m., 10 May
Late summit
Scott Fischer reaches the top very late and already failing; Hall remains near the summit with the client Doug Hansen.
Late afternoon, 10 May
The storm hits
A blizzard with winds over 100 km/h engulfs the upper mountain, producing whiteout conditions on the descent.
Night, 10–11 May
Lost on the Col
A group of clients becomes stranded in the open near the South Col; Boukreev makes repeated solo forays into the storm and brings several back alive.
Dawn, 11 May
Hall's last calls
Trapped near the South Summit, Hall radios that Hansen is gone and Andy Harris missing; he later speaks by patched radio to his wife, Jan Arnold, before dying.
11 May 1996
Fischer found
Sherpas reach Fischer on the southeast ridge near 8,300 m; he cannot be moved and dies; Boukreev recovers his body that evening.
11 May 1996
Weathers and Gau survive
Left for dead, the client Beck Weathers regains consciousness and walks into camp; he and Makalu Gau are later evacuated, both gravely frostbitten.
25 May 1996
A later death
The South African photographer Bruce Herrod, on the Col during the storm, summits alone two weeks later and dies on the descent at the Hillary Step.

The guided mountain

By 1996 Everest had become a commercial enterprise. Companies sold guided ascents of the highest mountain on Earth for sums in the tens of thousands of dollars, undertaking to shepherd paying clients of varied experience up the standard routes with fixed ropes, stocked camps, bottled oxygen and Sherpa support. Rob Hall's Adventure Consultants and Scott Fischer's Mountain Madness were among the most prominent operators, and both were on the south side that May with rosters of clients, guides and Sherpa staff. The model worked by managing risk through infrastructure and timing rather than by demanding that each climber be self-sufficient in the death zone — and that dependence on a smoothly running system was precisely what failed.

The southeast ridge route runs from the South Col at about 8,000 metres up to the Balcony, on along the ridge to the South Summit, across a corniced traverse to the Hillary Step — a short, steep rock pitch near 8,760 metres — and finally to the summit at 8,849 metres. Above the Col, climbers were deep in the death zone, where the body cannot acclimatize and deteriorates by the hour, and where most depended on bottled oxygen whose supply set a hard clock on how long anyone could remain. The route's narrow points, the Hillary Step chief among them, admit only one climber at a time, so any delay there backs up an entire column. The whole plan rested on reaching the top early enough to descend before both the oxygen and the daylight ran out.

The tenth of May

The teams left the South Col near midnight on 10 May. Almost at once the plan slipped: the fixed ropes that were meant to be in place at the Balcony and again at the Hillary Step had not been rigged, and climbers bunched up while guides and Sherpas installed them, bleeding away the morning's margin. Boukreev, climbing fast and without supplementary oxygen by his own method, reached the summit first around 1 p.m. and began descending. Behind him the column arrived in ones and twos through the afternoon, many well past the turnaround time that both leaders had nominally set. Doug Hansen, who had been turned back the previous year, pushed for the top very late with Hall staying alongside him; Fischer, already ill and exhausted, did not reach the summit until roughly 3:45 p.m.

Then the weather, which had been deteriorating, broke into a full storm. Wind reported above 100 km/h drove snow across the upper mountain and reduced visibility to nothing. Descending climbers lost the route on the broad, featureless South Col and a cluster of them — clients and guides from both teams, including Yasuko Namba and Beck Weathers — became stranded in the open, unable to find the tents only a few hundred metres away. In the worst of it, Boukreev went out alone again and again from Camp IV into the whiteout and brought several climbers back, one of the few unambiguous acts of rescue that night. Higher up, Hall was pinned near the South Summit with a failing Hansen; the guide Andy Harris went up to help and vanished. By dawn on 11 May the death zone held several people who would not come down.

The reckoning above 8,000 metres

The mountain gave up its toll slowly. From near the South Summit, Hall radioed down on the morning of 11 May that Hansen was gone and Harris missing, and that he himself could not move; in a final patched call he spoke to his wife, Jan Arnold, pregnant at home in New Zealand, before he died where he sat. Hansen and Harris were never found. Fischer, lower on the southeast ridge near 8,300 metres, was reached by Sherpas but was beyond saving; left in a sheltered spot, he died, and Boukreev recovered his body that evening. On the South Col, Namba died in the open, and Weathers, snow-blind and frostbitten, was twice judged beyond hope — yet he regained consciousness, stood, and walked into camp on his own, a survival no one had thought possible. He and the Taiwanese climber Makalu Gau were later evacuated by a daring high-altitude helicopter rescue, both maimed by frostbite.

Eight people died on 10 and 11 May 1996: Hall, Harris and Hansen and the client Yasuko Namba of Adventure Consultants; Fischer of Mountain Madness; and three members of an Indo-Tibetan Border Police team — Tsewang Samanla, Dorje Morup and Tsewang Paljor — who were caught by the same storm on the northeast ridge on the Tibetan side. The season's deaths reached twelve in all. The toll fell, as it always does on Everest, partly on the leaders whose ambition drove the schedule and partly on those who had the least choice about being there.

The Five Factors

01
Turnaround discipline abandoned
Both leaders had named a turnaround time, the single most important safety rule on a summit day, and both let it lapse under the pressure of clients close to a goal they had paid dearly to reach. Allowing summits at and after 2–4 p.m. guaranteed a descent into darkness and exhausted oxygen. A turnaround time that is not enforced is no rule at all.
02
Bottleneck and logistics failure
Ropes that should have been fixed in advance at the Balcony and the Hillary Step were not, and the single-file chokepoints turned that omission into hours of standing still in the death zone. A foreseeable logistical lapse consumed the very margin of daylight and oxygen the day's plan required.
03
Summit fever and commercial pressure
Paying clients and the operators selling them success were both invested in reaching the top, a pressure that pushes parties past sensible limits. Doug Hansen, turned back once before, was let to continue very late; the commercial stake in a summit quietly overrode the judgment that should have ordered a retreat.
04
A sudden storm with no shelter
The blizzard arrived fast and turned the open South Col into a whiteout in which climbers could not find tents a few hundred metres away. Above 8,000 metres there is no waiting out such weather; exposure kills within hours. Committing a large, slow party high on the mountain left it defenceless when the weather turned.
05
Oxygen, exhaustion and the rescue gap
Most climbers ran their bottled oxygen dry during the long delays, and judgment and strength collapsed with it; the leaders themselves were too spent to save their clients or descend. In the death zone there is almost no capacity for rescue — the would-be rescuers are as depleted as the stranded — so a single bad afternoon became fatal for many.

Aftermath

Eight climbers died across 10 and 11 May, and twelve over the season, then the deadliest in Everest's history. There was no formal inquiry in the legal sense, but the disaster produced an extraordinary public reckoning, driven by the fact that a journalist, Jon Krakauer, had been a client and lived to write Into Thin Air. Anatoli Boukreev, whose decision to descend ahead of clients Krakauer questioned, replied in The Climb and pointed to the lives he had saved on the Col that night; Boukreev himself died in an avalanche on Annapurna in December 1997. The competing accounts turned 1996 into the most argued-over episode in the sport, a permanent case study in the ethics of guiding amateurs into the death zone.

The mountain only grew busier. Continuous fixed ropes, better forecasting and industrial-scale oxygen logistics have since made the standard routes more survivable in good weather, yet the fundamental hazards — crowding at the bottlenecks, sudden storms, the death zone's clock — remain, and seasons with hundreds of climbers have brought their own deadly traffic jams. The disaster is remembered soberly as the moment the world saw what commercial Everest had become, and as a reminder that the heaviest and most routine risk on the mountain still falls on the Sherpas who fix the ropes, carry the loads and make every ascent possible.

Lessons

  1. Set a turnaround time before the summit day and enforce it absolutely; a peak reached too late is a death deferred.
  2. Rig the fixed ropes and clear the known bottlenecks in advance, because in the death zone lost hours cannot be recovered.
  3. Do not let a paying client's investment, or an operator's, override the judgment that should order a retreat.
  4. Build genuine rescue capacity into the plan, knowing that above 8,000 metres exhausted climbers cannot save one another.
  5. Credit the Sherpa staff whose trail-breaking, rope-fixing and rescues underpin every Everest ascent, rather than crediting only the named leaders and clients.
