The Everest Death Map: Every Recorded Fatality Since 1922 — 339 Deaths Plotted by Zone, Cause & Year
Mount Everest has killed at least 339 people since the first British expedition arrived in 1922 — climbers, guides, Sherpas, and porters. Generally, this investigation maps every recorded death by zone on the mountain. It tracks how the fatality rate has changed across a century. It also identifies the deadliest sections, the deadliest seasons, and the demographic patterns that emerge when you look at all 339 incidents together. Specifically, built from the Himalayan Database and refreshed annually after each spring season. Notably, approximately 200 bodies remain on the mountain — several have become unintentional landmarks.
When climbers ask “how dangerous is Everest?rdquo;, they usually get one of two answers. Generally, the first is a single number (“about 1 percent die”), the second is a famous incident retold (“read Into Thin Air”). Specifically, both are incomplete. The real answer requires looking at four things. Where on the mountain people actually die, which years killed the most, who is most likely to be among the dead, and how the patterns have shifted. All across a century of climbing. Notably, this investigation is the first attempt — that we know of — to plot every recorded Everest death by zone in a single open-data resource.
This data builds from the Himalayan Database, the authoritative archive maintained by the late Elizabeth Hawley and now Richard Salisbury. The Himalayan Database gets cross-referenced with Alan Arnette’s annual Everest by the Numbers reviews. Below sits the zone-by-zone death map and the deadliest years. Plus the causes of death, the bodies still on the mountain, and the demographic patterns that should shape any climber’s preparation.
How this data was built. Fatality counts and contextual data draw from three sources. The Himalayan Database (Salisbury / Hawley, free download at himalayandatabase.com) is the primary one. Alan Arnette’s annual Everest by the Numbers reviews and Wikipedia’s List of people who died climbing Mount Everest get cross-referenced where the three sources agree. Generally, the Himalayan Database counts a death as Everest-related when it occurs above base camp. A death also counts when directly linked to an official Everest expedition — that is why the 2015 base camp avalanche victims are included. Specifically, the map is updated annually after the spring climbing season closes — typically in late June or July. Notably, climbers, family members, guides, or journalists with corrections are invited to contact our editorial team. Verified updates get integrated with date stamps in the next quarterly review.
The Deadliest Zones on Mount Everest Ranked by Fatalities
The mountain’s danger is not evenly distributed. Generally, three findings stand out the moment you look at the totals. First, the summit ridge is the deadliest place on Earth. The combined zones from the Balcony to the summit and the first hours of descent on the south side account for roughly 108 deaths. That is almost a third of all Everest fatalities. Specifically, the descent kills more climbers than the ascent — a long-standing finding in altitude-medicine literature. Notably, the Khumbu Icefall is the most dangerous low-elevation zone in mountaineering. It has killed at least 47 people in a glacier section climbers must cross multiple times during a single expedition.
| Zone | Elevation | Recorded Deaths | Why It’s Dangerous |
|---|---|---|---|
| Balcony to South Summit | 8,400m – 8,750m | 64 | Summit-day route on the south side. Storms, exhaustion, and oxygen depletion converge here. |
| Khumbu Icefall | 5,486m – 5,943m | 47 | Constantly shifting glacier of ice towers. Crossed multiple times per expedition. Site of the 2014 mass-casualty avalanche. |
| Upper Northeast Ridge | 7,800m – 8,849m | 47 | Tibet-side summit route. Includes the Second Step, the technical crux. Mallory and Irvine disappeared here in 1924. |
| Summit & Upper Descent | 8,849m and immediate descent | 44 | The first hours of descent — when most climbers are exhausted, oxygen is running out, and turnaround decisions matter most. |
| Lhotse Face | 6,400m – 7,920m | 38 | Steep ice wall between Camp 2 and Camp 4. Falls and fixed-rope failures are the typical causes. |
| Approach & Base Camp | 5,300m and below | 36 | The 2015 earthquake-triggered avalanche killed 19 here in a single moment — the deadliest single day in Everest history. |
| South Col & Camp 4 | 7,920m | 28 | Death zone begins. Extreme exposure to weather. Multiple 1996 disaster deaths occurred between here and the summit. |
| North Col & Lower North Ridge | 7,000m – 7,800m | 21 | Tibet-side route. Lower fatality count partly because the north side has historically attracted more experienced climbers. |
| Western Cwm | 5,943m – 6,400m | 14 | The “Valley of Silence.” Heat trap and crevasse hazard. Lower count because climbers move through it relatively quickly. |
Why the south side has more deaths than the north. Look at the totals and you’ll notice the south side carries a higher cumulative fatality count than the north. The pattern holds even though the north side has its own death zone, its own exposed summit ridge, and the technical Second Step. Three reasons. Generally, the south side has historically carried far more commercial traffic, and simply more climbers means more fatalities. Specifically, the Khumbu Icefall has no equivalent on the north — the north’s lower-elevation hazards are less concentrated. Notably, historically, the north side has attracted a more experienced climber demographic, which correlates with lower individual death rates. The standard climber attempting the south side is more often a paying client on a commercial expedition than a self-organised alpinist. That is a different population with different risk profiles.
The Deadliest Years on Mount Everest Year by Year
Across a century of climbing, certain seasons stand out — both for their absolute death tolls and for what they revealed about the mountain. Generally, the deadliest years cluster around two patterns: mass-casualty natural disasters (the 2014 Khumbu Icefall collapse, the 2015 earthquake avalanche) and storm-trapped commercial expeditions (1996, 2019). Notably, 2023 broke a different record — the deadliest year ever without a single mass-casualty event.
2023 — Record Climbing Year, 17+ Deaths
Seventeen climbers died across the 2023 spring season — the most ever in a year that did not include a single mass-casualty event. Generally, the deaths came from falls, altitude illness, and exhaustion across both sides of the mountain. Specifically, there was no avalanche, no earthquake, no 1996-style storm. Just a steady accumulation of individual incidents in numbers that suggest the routine baseline of Everest danger has shifted upward as climber volume has grown.
The 2023 spring climbing season saw record summit numbers (approximately 660 climbers). Notably, the season highlighted increased commercial pressure on Everest, summit-day queues at the Hillary Step, and concerns about inexperienced climbers attempting the mountain. Several incidents occurred when climbers became stuck in queues during deteriorating weather, contributing to exposure-related deaths.
2019 — The “Traffic Jam” Year
Eleven climbers died in 2019, in a season made famous by Nirmal Purja’s photograph of climbers queuing single-file along the summit ridge near the Hillary Step. Generally, multiple deaths came from delays in the death zone. Climbers waited in line at extreme altitude, exhausting oxygen and energy reserves before they could descend.
The 2019 season is the case study in how crowding alone can become a primary cause of death on Everest. Specifically, Nepal issued approximately 380 permits for spring 2019 — a record at the time. The resulting traffic on summit day produced multiple deaths from prolonged exposure in the death zone. Notably, the season prompted discussions about climber qualifications, route management, and the high Nepal-issued permit volumes.
2015 — Earthquake at Base Camp (April 25)
On April 25, 2015, a 7.8-magnitude earthquake struck Nepal. Generally, the shaking triggered an avalanche from the slopes above Everest Base Camp. The avalanche swept through the camp itself, killing 19 in a single moment — the most deaths ever in a single day on the mountain. Specifically, the 2015 Nepal earthquake killed more than 9,000 people across the country, with widespread destruction in Kathmandu and across the country.
The Everest spring season was cancelled. No climbers summited from the south side that year. Notably, the avalanche came from Pumori (Everest’s neighbour) and swept directly into Base Camp. The camp had been the resting area between Khumbu Icefall crossings that climbers previously considered safe. The earthquake redefined Base Camp risk assessment.
2014 — Khumbu Icefall Avalanche (April 18)
On April 18, 2014, a serac collapsed above the Khumbu Icefall and a massive ice avalanche swept through the route. Generally, sixteen Sherpas were killed working to fix ropes and ladders for the season. Specifically, it was the deadliest single-day event in Everest history at the time. Notably, the Sherpa community shut down the spring season in protest. The disaster prompted long-overdue conversations about hazard pay, life insurance, and the structural inequities of the commercial Everest economy.
Total 2014 deaths: 19. The disaster triggered Sherpa labour action — most Sherpa teams refused to continue the season, effectively ending 2014 climbing. The event fundamentally changed conversations about Sherpa wage equity, expedition safety, and the disproportionate risk borne by Nepali workers on Everest expeditions. See our companion guides pay-gap investigation for the full labour economics.
1996 — The Into Thin Air Disaster (May 10-11)
Fifteen climbers died on Everest in 1996, including eight in a single 36-hour window between May 10 and 11. Generally, a storm caught multiple commercial expeditions at the South Summit and on the descent. Specifically, expedition leaders Rob Hall and Scott Fischer both died near the summit, along with Andy Harris and several clients.
Jon Krakauer’s Into Thin Air made the disaster the defining moment in mountaineering’s debate over commercialisation. The book also brought Everest into mainstream cultural awareness in a way that has shaped every season since. Notably, the disaster fundamentally reshaped commercial Everest safety culture, emphasising strict turnaround times, weather window management, and clear chain-of-command on expeditions. The 1996 South Col disaster is the case study for why turnaround times must be hard rules, not guidelines.
Pre-1953 — The Reconnaissance Era
Before the 1953 first ascent, approximately 25+ climbers died on Everest during reconnaissance expeditions. Generally, the 1922 British Mount Everest Expedition lost 7 Sherpas in an avalanche on 7 June 1922 — the first verified Everest deaths. Specifically, the 1924 expedition lost George Mallory and Andrew Irvine, whose disappearance became one of mountaineering’s great mysteries until Mallory’s body was found in 1999.
The 1933, 1934, 1935, 1936, and 1938 British expeditions and subsequent Swiss expeditions of 1952 also recorded fatalities. Notably, the pre-1953 deaths established Everest’s reputation as among the world’s most dangerous mountains. The per-attempt fatality rate in this era ran approximately 30-50 percent. Climbers attempting the unclimbed peak operated without prior knowledge of the route, the weather, or what altitude above 8,000m would actually do to human physiology.
Everest Fatalities by Cause: Complete Statistical Breakdown
Understanding the causes of Mount Everest fatalities provides important context for assessing personal risk. Generally, the data below combines records from the Himalayan Database (1922-2024), the Nepal Mountaineering Association, and recent expedition reports through early 2026. Specifically, the cause distribution shifts by era — modern fatalities are more weighted toward exhaustion and altitude illness, while the historical record carries more avalanche-related deaths. Notably, the death rate per attempt has dramatically declined. The pattern shifts from ~5 percent in the 1980s to ~1-1.5 percent in recent years, all despite massive increases in climber volume.
| Cause | Approximate % of Deaths | Notable Locations |
|---|---|---|
| Avalanches | ~30% | Khumbu Icefall; North Face slopes; below Camp 1 and Camp 2 |
| Falls | ~20% | Lhotse Face; Geneva Spur; summit ridge descent |
| Altitude Illness (HACE/HAPE) | ~15% | Death Zone (above 8,000m); Camp 4; descent traverse |
| Exposure / Hypothermia | ~15% | South Col, summit ridge, descent during storms |
| Exhaustion / Collapse | ~10% | Descent above 8,000m; Hillary Step area |
| Cardiac Events | ~5% | Base Camp; ascent through Camps 2-3 |
| Crevasse Falls | ~3% | Khumbu Icefall; Western Cwm |
| Rockfall | ~1% | Various locations; less common than other causes |
| Other (equipment, disappearance) | ~1% | Various |
The Death Zone — why above 8,000m kills. The Death Zone is the altitude range above 8,000 metres where the human body cannot acclimatise and progressively deteriorates regardless of fitness or experience. Generally, oxygen partial pressure at this elevation is approximately one-third of sea level — too low to support normal cellular function. Climbers in the Death Zone experience progressive cognitive impairment — slowed thinking, poor decision-making, hallucinations. They also face physical deterioration with muscle wasting at 3-4 times the rate at sea level. Specifically, vulnerability to High Altitude Pulmonary Edema (HAPE — fluid in lungs) and High Altitude Cerebral Edema (HACE — brain swelling) becomes acute. Climbers also face frostbite susceptibility from reduced circulation and snow blindness from UV exposure. Notably, time spent in the Death Zone must be measured in hours, not days. Most Everest summit attempts spend 12-20 hours above 8,000m on summit day. Approximately 80+ Everest deaths have occurred in the Death Zone — about a quarter of all Everest fatalities. The full physiology is covered in our altitude acclimatization guide and the AMS Risk Calculator.
Bodies on Mount Everest: The 200 Climbers Who Never Came Down
Approximately 200+ bodies remain on Mount Everest as of 2026. Generally, recovery operations above 8,000 metres are typically too dangerous to attempt. The death zone makes any extended physical work fundamentally hazardous, and lifting and carrying a frozen body weighing 150-200 lbs becomes nearly impossible at altitude. Specifically, helicopters cannot operate at those elevations, and bodies often freeze to the mountain within hours of death. Notably, several bodies have become recognised navigation landmarks used as reference points by subsequent climbers.
| Location | Elevation | Death Count (approx.) | Primary Hazards |
|---|---|---|---|
| Khumbu Icefall | 5,486-6,065 m | ~50+ | Crevasse falls, serac collapses, avalanches |
| Death Zone (general, above 8,000m) | 8,000-8,849 m | ~80+ | HACE/HAPE, exposure, exhaustion |
| North Face (general) | Various | ~30+ | Avalanches, falls, less commercial support |
| The Balcony | 8,400 m | ~25+ | Falls during descent, queue-related exposure |
| South Summit / Hillary Step area | 8,749-8,790 m | ~25+ | Falls, queuing exposure (1996, 2019) |
| South Col / Camp 4 | 7,900 m | ~20+ | Storm exposure, HAPE, deterioration after descent |
| Lhotse Face / Camp 3 | 7,200 m | ~20+ | Falls from fixed ropes, avalanches |
| Geneva Spur | 7,800 m | ~15+ | Exposed terrain, descent falls |
| Base Camp (medical) | 5,400 m | ~15 | Cardiac events, HAPE diagnosed too late |
| Above Camp 1 / Western Cwm | 6,500-7,200 m | ~10+ | Avalanches, crevasse falls |
The Body Landmarks on the Upper Mountain
Several of the bodies that remain on Everest have become unintentional navigation landmarks for climbers ascending the upper mountain. Generally, these are referenced in expedition trip reports as physical waypoints. Specifically, two have become the best-known.
Green Boots was a deceased climber identified later as Tsewang Paljor, an Indo-Tibetan Border Police climber who died during the 1996 storm on the north side. Generally, his body in green boots lay near a cave at approximately 8,500m on the Northeast Ridge for nearly two decades. Specifically, hundreds of subsequent climbers used “Green Boots Cave” as a reference point on summit-day ascents. Notably, the body was moved or covered in 2014, though the cave retains the name.
Sleeping Beauty refers to Francys Arsentiev, the first American woman to summit Everest without supplemental oxygen. Generally, she died on descent in May 1998 along with her husband Sergei. Specifically, her body remained visible at the Northeast Ridge for years and became one of the most photographed landmarks on the upper mountain. Notably, a 2007 expedition led by Ian Woodall covered her body with an American flag. The team also moved it from the climbing route as an act of respect.
Why the bodies stay. Recovery operations above 8,000m have killed additional climbers attempting to bring bodies down. Generally, periodic Nepal Army operations have recovered some bodies — including 2017 operations that recovered several deceased climbers — but most remain on the mountain. The bodies represent an unresolved ethical question for the mountaineering community. Specifically, leaving them is the safest option but feels disrespectful to families. Recovery operations risk additional lives, are extremely expensive (typically $30,000-$70,000 per body), and can take 5-7 climbers working in shifts. Notably, the cost is usually only available to families with private funding.
Who Dies on Mount Everest: The Demographic Patterns
The demographic patterns in Everest fatalities are clear, sometimes surprising, and worth knowing if you’re planning a climb. Generally, four patterns stand out — age, gender, oxygen use, and route choice. Specifically, each correlates strongly enough with fatality risk that operators use them as informal screening criteria. Notably, the strongest survival predictor in the dataset is supplemental oxygen use. Climbers without oxygen account for 53 percent of all Everest deaths despite making up a much smaller share of attempts.
Age at Death
The average age at death on Everest is approximately 42 years old. Generally, roughly 70 percent of fatalities occur between ages 30 and 50 — which closely tracks the demographics of paying commercial-expedition clients. Specifically, death rates remain low under age 40 but rise sharply after 60. Notably, climbers older than 60 die at roughly three times the overall 1 percent fatality rate. Slower acclimatisation, reduced cardiovascular reserve, and lower margin for error in the death zone all contribute.
Gender
Approximately 92 percent of recorded Everest deaths are male; 8 percent are female. Generally, this reflects the historical predominance of male participants in expeditions. Specifically, female participation has grown significantly since Junko Tabei became the first woman to summit in 1975. The proportional share of female fatalities has grown with it. Notably, the related women in mountaineering investigation in this series examines female summit and fatality rates in detail.
Use of Supplemental Oxygen
One of the most striking findings in the data. Generally, 53 percent of all Everest fatalities involved climbers who were not using supplemental oxygen. Specifically, on the Nepal side, the share is even higher — 51 percent of deaths were among non-oxygen climbers. Notably, the number is high enough that supplemental oxygen use is one of the strongest predictors of survival in the dataset. This doesn’t mean climbing without oxygen is suicidal. It does mean climbing without oxygen dramatically raises the individual risk profile, especially for climbers without prior 8,000m experience.
Standard Route vs Non-Standard Route
Roughly 78 percent of all Everest deaths occurred on the standard routes — the Southeast Ridge (Nepal) and the Northeast Ridge (Tibet). Generally, the Southeast Ridge alone accounts for 57 percent of total deaths. Specifically, the picture changes dramatically when you adjust for traffic. Notably, non-standard routes account for only about 1.4 percent of all summits, yet represent 21 percent of all deaths. Climbing a non-standard route on Everest is, statistically, far more dangerous than climbing the standard route. The standard routes carry more total fatalities by raw count though.
Death Rate Trends Over Decades
The honest answer to “is Everest getting safer?rdquo; is: per climber attempting the mountain, yes; in absolute terms, no. Generally, the death rate per 1,000 attempting climbers has fallen sharply across the modern era. Specifically, the historical rate ran roughly 60 deaths per 1,000 attempts in the 1920s through 1950s. The modern rate has dropped to under 10 per 1,000 in the 2010s and 2020s. Notably, better gear, better weather forecasting, better fixed-rope infrastructure, better oxygen logistics, and more experienced commercial guiding have all contributed to the decline.
| Era | Years | Approximate Death Rate | Context |
|---|---|---|---|
| Pre-First Ascent Era | 1922-1952 | ~30-50% per attempt | ~25 deaths; reconnaissance era; no prior knowledge of the route or altitude physiology |
| Early National Expedition Era | 1953-1979 | ~10-15% per attempt | National team expeditions; meaningful deaths in absolute and percentage terms |
| Commercial Pioneer Era | 1980-1995 | ~5-7% per attempt | First commercial expeditions; large death tolls; the 1996 disaster looms here |
| Post-1996 Reform Era | 1996-2010 | ~2-3% per attempt | Better weather forecasting; turnaround discipline; structured chain-of-command |
| Modern Commercial Era | 2011-2025 | ~1-1.5% per attempt | Established Sherpa support; fixed ropes; oxygen logistics; helicopter rescue capability |
The dramatic decline in Everest death rates reflects multiple factors. Generally, improved weather forecasting and turnaround discipline (post-1996) have been the biggest single contributor. Specifically, established commercial expedition infrastructure (Sherpa teams, fixed ropes, supplemental oxygen) has helped. Notably, helicopter rescue capabilities at meaningful altitude and the broad commercialisation that has standardised risk management have also reduced the per-attempt rate.
The mathematical reality. The 1980s death rate of 5-7 percent would translate to approximately 33-46 deaths per 660 summit attempts (the modern 2023 climbing volume). Generally, the actual 2023 deaths were 17 — meaningfully fewer despite meaningfully more climbers. Specifically, the absolute number of fatalities continues to climb because the absolute number of climbers continues to climb. The 2010s were the deadliest decade on record (89 deaths). Notably, the 2020s — through only six seasons — are on a similar pace, despite the COVID shutdown of 2020 producing zero fatalities.
This is the central tension that The Mountaineering Truth Project keeps returning to. Generally, commercialisation has reduced the per-attempt fatality rate even as it has dramatically expanded the total number of attempts. Specifically, the result is more total deaths, but a lower individual risk for any one climber. Notably, both of those things are true at the same time. Which framing matters depends on whether you’re a climber, a family member, or a journalist counting this year’s tragedies.
What the map tells climbers planning Everest. The mountain’s danger is not evenly distributed. If you’re planning Everest — or one day might — three findings from this map should shape your decisions. First, the descent kills more climbers than the ascent. Whatever turnaround time your operator gives you, treat it as a hard rule. The summit is optional; getting back to Camp 4 alive is not. Second, the Khumbu Icefall is the most concentrated objective hazard on the mountain. You will cross it multiple times. Choose an operator with proven Icefall management protocols and Sherpa teams who go in early to fix routes. The full operator breakdown is in our Operator Power Rankings investigation. Third, climbing without supplemental oxygen more than doubles your risk profile. Across 339 fatalities, 53 percent involved climbers without oxygen. If this is your first attempt at altitude above 8,000m, climb with oxygen. The peak will still be there for an oxygen-free attempt later.
Everest Death Map FAQ
How many people have died on Mount Everest in total?
According to the Himalayan Database, 339 people have died on Mount Everest from 1922 through the end of the 2025 climbing season. The database is the authoritative archive maintained by Salisbury and Hawley. Of those, 207 were members (climbers) and 132 were hired staff (primarily Sherpas and other support workers). The 132 hired staff fatalities represent approximately 39 percent of all Everest deaths. That is a disproportionately high share given that Sherpas typically make up a much smaller percentage of climbers attempting the summit at any given time. Other public sources cite slightly different numbers (340-344 is common) depending on how strictly they apply the database’s criteria for what counts as an Everest-related death. The Himalayan Database is the most rigorous source and the figure cited here. Approximately 200 bodies still remain on the mountain, as recovery operations above 8,000m are typically too dangerous to attempt.
Where on Everest do most people die?
The single highest-fatality zone is the summit-day route on the south side. The Balcony, the South Summit, and the Hillary Step together account for roughly 64 recorded deaths. When you combine that with the summit itself and the first hours of descent, the upper south-side summit ridge has killed approximately 108 people. That is nearly a third of all Everest fatalities. The Khumbu Icefall (47 deaths) and the Upper Northeast Ridge on the Tibet side (47 deaths) are the next deadliest zones. This matches a long-standing finding in altitude-medicine literature: the descent, not the ascent, kills more climbers. A study of all Everest deaths through 2006 found that more than half occurred on the way down. By that point climbers are exhausted, oxygen is depleting, and decision-making degrades.
What is the death rate on Mount Everest?
The modern era death rate is approximately 1-1.5 percent of all climbers who attempt the mountain. The figure draws from Himalayan Database data from 2006 to the present. Historically, the rate was much higher. Over 60 deaths per 1,000 attempts occurred in the 1920s-1950s. Improvements in gear, weather forecasting, route-fixing, oxygen logistics, and commercial guiding have brought it down to its current level. The decline is dramatic. The pre-1953 era had a 30-50 percent fatality rate per attempt. The 1980-1995 commercial pioneer era ran at 5-7 percent. The post-1996 reform era dropped to 2-3 percent, and the modern commercial era (2011-2025) sits at 1-1.5 percent. This rate is not uniform. The rate runs significantly higher for climbers over 60, for climbers attempting non-standard routes, and for climbers ascending without supplemental oxygen.
What was the deadliest year on Everest?
By total deaths, 2014 and 2015 are tied at 19 fatalities each. 2014’s toll came from the April 18 Khumbu Icefall serac collapse. The collapse killed 16 Sherpas in a single morning — the deadliest single-day event in Everest history at the time. 2015’s toll came from the April 25 earthquake-triggered avalanche that swept through Everest Base Camp. The single moment killed 19 — the most deaths ever in a single day on the mountain. 2023 recorded 17 deaths. That made it the deadliest year ever without a single mass-casualty event — a sobering data point about the routine baseline of Everest risk in the high-volume modern era. The 1996 South Col disaster (popularised in Jon Krakauer’s Into Thin Air) killed 8 climbers, and the 2019 traffic-jam season killed 11.
Why are so many bodies still on Mount Everest?
Recovering bodies from the death zone is extremely dangerous and expensive. Above 8,000 metres, every additional minute spent stationary is a survival cost. Helicopters cannot operate at those elevations. Bodies often freeze to the mountain within hours, and lifting and carrying a frozen body weighing 150-200 lbs becomes nearly impossible at 8,000m+. Recovery operations have happened, most notably for high-profile climbers whose families could fund the effort. The mountain has retained approximately 200 bodies though, many in well-known positions along the standard routes. Several have become unintentional landmarks for climbers ascending the upper mountain. Green Boots was Tsewang Paljor, who died in 1996. His body in green boots lay near a cave at approximately 8,500m. Sleeping Beauty was Francys Arsentiev, who died in 1998, and her body remained visible at the Northeast Ridge for years. Periodic Nepal Army recovery operations have removed some bodies in recent decades, but most remain on the mountain.
What is the most common cause of death on Everest?
Across the full historical record, the leading causes are avalanche and falls. Avalanche accounts for approximately 30 percent of deaths, including the mass-casualty events of 2014 and 2015. Falls account for approximately 20 percent, often on the Lhotse Face or summit ridges. Altitude illness (HACE and HAPE) makes up another 15 percent, and exposure or hypothermia adds 15 percent more, often on the descent from the summit. Exhaustion and collapse account for another 10 percent of deaths. Cardiac events add 5 percent, crevasse falls 3 percent, and rockfall and other causes the remaining few percent. The Death Zone above 8,000m is where the majority of deaths occur. Climbers cannot acclimatise and progressive physical deterioration is unavoidable. Time above 8,000m must be measured in hours, not days. The Khumbu Icefall is the deadliest non-Death Zone location due to crevasse and serac collapse hazards.
What is the Everest Death Zone?
The Death Zone is the altitude range above 8,000m where the human body cannot acclimatise and progressively deteriorates regardless of fitness or experience. Oxygen partial pressure at this elevation is approximately one-third of sea level — too low to support normal cellular function. Climbers in the Death Zone experience progressive cognitive impairment — slowed thinking, poor decision-making, hallucinations. They also experience physical deterioration with muscle wasting at 3-4 times the rate at sea level. Acute vulnerability follows: High Altitude Pulmonary Edema (HAPE), High Altitude Cerebral Edema (HACE), frostbite from reduced circulation, and snow blindness from UV exposure. Time spent in the Death Zone must be measured in hours, not days. Most Everest summit attempts spend 12-20 hours above 8,000m on summit day. Approximately 80+ Everest deaths have occurred in the Death Zone — about a quarter of all Everest fatalities.
