The Everest Death Map: Every Fatality Since 1922, Plotted by Cause and Location
Mount Everest has killed at least 339 people since the first British expedition arrived in 1922 — climbers, guides, Sherpas, and porters. This investigation maps every recorded death by zone on the mountain, tracks how the fatality rate has changed across a century, and identifies the deadliest sections, the deadliest seasons, and the patterns that emerge when you look at all 339 incidents together. Built from the Himalayan Database. Updated annually after each spring season.

When climbers ask “how dangerous is Everest?”, they usually get one of two answers: a single number (“about 1% die”), or a famous incident retold (“read Into Thin Air”). Both are incomplete. The real answer requires looking at 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 across a century of climbing. This investigation is the first attempt — that we know of — to plot every recorded Everest death by zone in a single interactive resource. The map below is built from the Himalayan Database, the authoritative archive maintained by the late Elizabeth Hawley and now Richard Salisbury. Click any zone to see the recorded deaths and major incidents in that part of the mountain.
The Map
Every dot below represents a section of Mount Everest. The number inside each dot is the count of recorded deaths in that zone since 1922. Click or tap to see the major incidents that occurred there, the elevation profile, and what makes that part of the mountain dangerous.
Sources. Fatality counts and contextual data are drawn from the Himalayan Database (Salisbury / Hawley, free download at himalayandatabase.com), Alan Arnette’s annual Everest by the Numbers reviews — the most thorough independent statistical review of each Everest season — and Wikipedia’s List of people who died climbing Mount Everest, cross-referenced where the three sources agree. What’s counted. The Himalayan Database counts a death as Everest-related when it occurs above base camp or is directly linked to an official Everest expedition (so the 2015 base camp avalanche victims are included). Zone assignment. Each death is assigned to the zone on the mountain where it occurred. Some historical fatalities have uncertain locations; we’ve reconciled across sources and counted conservatively. What’s not counted. Trekkers who die on the trek to base camp without being part of an Everest expedition. Helicopter and Lukla flight fatalities not associated with an expedition. Pre-1922 reconnaissance deaths from approach routes outside Nepal/Tibet. Refresh cadence. The map is updated annually after the spring climbing season closes — typically in late June or July.
What the numbers show
Three findings stand out the moment you look at the totals.
1. 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 — almost a third of all Everest fatalities. The Northeast Ridge from 7,800m up adds another 47. When climbers ask “where do most people die,” the answer is on summit day, above 8,400 meters, often within hours of reaching the top.
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. Climbers are exhausted. Oxygen is depleting. Decision-making degrades. The summit is reached, the goal is achieved — and then the most dangerous hours begin.
2. The Khumbu Icefall is the most dangerous low-elevation zone in mountaineering.
The Khumbu Icefall — the section of glacier between Base Camp and Camp 1 — has killed at least 47 people. It is, by some measures, the most dangerous part of any peak in the world that climbers must repeatedly cross. The 2014 disaster, in which a serac collapse killed 16 Sherpas in a single morning, remains the deadliest single Khumbu Icefall event in history. The danger is structural: there is no way to climb the south side of Everest without crossing it, often four or five times during a single expedition.
3. Sherpas die at a disproportionate rate.
Of the 339 total Everest deaths, 132 were hired staff — primarily Sherpas, Tamangs, Magars, and other support workers. That’s 39% of all fatalities, a number that becomes more striking when you consider that Sherpas typically make up a much smaller percentage of climbers attempting the summit at any given time. The Khumbu Icefall is the worst of it: when route-fixing teams enter at 3am to set ropes and ladders, they’re exposing themselves to objective hazard that paying clients will only cross briefly later in the morning. Investigation 15 of this series examines the labor economics of high-altitude climbing in detail.
The deadliest zones, ranked
| 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 to the upper mountain. 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 fatality count because climbers move through it relatively quickly. |
Look at the totals and you’ll notice the south side carries a higher cumulative fatality count than the north — even though the north side has its own death zone, its own exposed summit ridge, and the technical Second Step. Three reasons: (1) the south side has historically carried far more commercial traffic, simply more climbers means more fatalities; (2) the Khumbu Icefall has no equivalent on the north — the north’s lower-elevation hazards are less concentrated; and (3) 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-organized alpinist — a different population with different risk profiles.
The deadliest years on Everest
Across a century of climbing, certain seasons stand out — both for their absolute death tolls and for what they revealed about the mountain.
1996 — The Into Thin Air disaster
Fifteen climbers died on Everest in 1996, including eight in a single 36-hour window between May 10 and 11. A storm caught multiple commercial expeditions at the South Summit and on the descent. Expedition leaders Rob Hall and Scott Fischer both died near the summit. Jon Krakauer’s Into Thin Air made the disaster the defining moment in mountaineering’s debate over commercialization — and brought Everest into mainstream cultural awareness in a way that has shaped every season since.
2014 — Khumbu Icefall avalanche
On April 18, 2014, a serac collapsed above the Khumbu Icefall and a massive ice avalanche swept through the route. Sixteen Sherpas were killed working to fix ropes and ladders for the season. It was the deadliest single-day event in Everest history at the time. The Sherpa community shut down the spring season in protest, and the disaster prompted long-overdue conversations about hazard pay, life insurance, and the structural inequities of the commercial Everest economy. Total 2014 deaths: 19.
2015 — Earthquake at base camp
On April 25, 2015, a 7.8-magnitude earthquake struck Nepal. The shaking triggered an avalanche from the slopes above Everest Base Camp that swept through the camp itself, killing 19 in a single moment — the most deaths ever in a single day on the mountain. The 2015 Nepal earthquake killed more than 9,000 people across the country. The Everest spring season was cancelled. No climbers summited from the south side that year.
2019 — The traffic-jam season
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. Multiple deaths were attributed to delays in the death zone — climbers waiting 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.
2023 — Highest non-disaster total on record
Seventeen climbers died across the 2023 spring season — the most ever in a year that did not include a single mass-casualty event. The deaths came from falls, altitude illness, and exhaustion across both sides of the mountain. 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.
Who dies on Everest
The demographic patterns in Everest fatalities are clear, sometimes surprising, and worth knowing if you’re planning a climb.
Age
The average age at death on Everest is approximately 42 years old. Roughly 70% of fatalities occur between ages 30 and 50 — which closely tracks the demographics of paying commercial-expedition clients. Death rates remain low under age 40 but rise sharply after 60 — climbers older than 60 die at roughly three times the overall 1% fatality rate, due in part to slower acclimatization, reduced cardiovascular reserve, and lower margin for error in the death zone.
Gender
Approximately 92% of recorded Everest deaths are male; 8% are female. This reflects the historical predominance of male participants in expeditions. Female participation has grown significantly since Junko Tabei became the first woman to summit in 1975, and the proportional share of female fatalities has grown with it. Investigation 13 of this series examines female summit and fatality rates in detail.
Use of supplemental oxygen
One of the most striking findings in the data: 53% of all Everest fatalities involved climbers who were not using supplemental oxygen. On the Nepal side, the share is even higher — 51% of deaths were among non-oxygen climbers. 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, but it does mean it dramatically raises the individual risk profile, especially for climbers without prior 8,000m experience.
Standard route vs. non-standard route
Roughly 78% of all Everest deaths occurred on the standard routes — the Southeast Ridge (Nepal) and the Northeast Ridge (Tibet). The Southeast Ridge alone accounts for 57% of total deaths. But the picture changes dramatically when you adjust for traffic: non-standard routes account for only about 1.4% of all summits, yet represent 21% of all deaths. Climbing a non-standard route on Everest is, statistically, far more dangerous than climbing the standard route — even though the standard routes carry more total fatalities by raw count.
Is Everest getting safer?
The honest answer is: per climber attempting the mountain, yes; in absolute terms, no.
The death rate per 1,000 attempting climbers has fallen sharply across the modern era. From roughly 60 deaths per 1,000 attempts in the 1920s through 1950s, the rate has dropped to under 10 per 1,000 in the 2010s and 2020s. Better gear, better weather forecasting, better fixed-rope infrastructure, better oxygen logistics, and more experienced commercial guiding have all contributed.
But 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). The 2020s — through only six seasons — are on a similar pace, despite the COVID-shutdown of 2020 producing zero fatalities. The mountain has not become safer for the individual climber as fast as it has become more accessible.
This is the central tension that the Mountaineering Truth Project keeps returning to: commercialization has reduced the per-attempt fatality rate even as it has dramatically expanded the total number of attempts. The result is more total deaths, but a lower individual risk for any one climber. 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.
Frequently Asked Questions
How many people have died on Mount Everest in total?
According to the Himalayan Database — the authoritative archive maintained by Salisbury and Hawley — 339 people have died on Mount Everest from 1922 through the end of the 2025 climbing season. Of those, 207 were members (climbers) and 132 were hired staff (primarily Sherpas and other support workers). 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 and the figure cited here.
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, which 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 — 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.
What is the death rate on Mount Everest?
The modern era death rate is approximately 1% of all climbers who attempt the mountain, based on Himalayan Database figures from 2006 to the present. Historically, the rate was much higher — over 60 deaths per 1,000 attempts in the 1920s–1950s — but improvements in gear, weather forecasting, route-fixing, oxygen logistics, and commercial guiding have brought it down to its current level. However, this rate is not uniform: it is 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 was driven by the April 18 Khumbu Icefall serac collapse that killed 16 Sherpas. 2015’s was driven by the April 25 earthquake-triggered avalanche that swept through Everest Base Camp, killing 19 in a single moment. 2023 recorded 17 deaths, making 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.
Why are so many bodies still on Mount Everest?
Recovering bodies from the death zone is extremely dangerous and expensive. Above 8,000 meters, every additional minute spent stationary is a survival cost. Helicopters cannot operate at those elevations. Bodies often freeze to the mountain within hours. Recovery operations have happened — most notably for high-profile climbers whose families could fund the effort — but the mountain has retained roughly 200 bodies, many in well-known positions along the standard routes. Several have become unintentional landmarks for climbers ascending the upper mountain.
What is the most common cause of death on Everest?
Across the full historical record, the leading causes are avalanche (76 deaths, including the mass-casualty events of 2014 and 2015), falls (71 deaths, often on the Lhotse Face or summit ridges), altitude illness (HACE and HAPE — 51 deaths), and exhaustion / exposure (49 deaths, often on the descent from the summit). Frostbite is a contributing factor in many fatalities and a primary cause in a smaller subset. The exact distribution shifts by era — modern fatalities are more weighted toward exhaustion and altitude illness, while the historical record carries more avalanche-related deaths.
How is this data updated?
The Everest Death Map is refreshed annually after the spring climbing season closes — typically in late June or July. We pull updated figures from the Himalayan Database, cross-reference with Alan Arnette’s annual Everest by the Numbers review, and update the zone counts, year-by-year totals, and major incident list. The interactive map itself updates automatically when we push new data — the article you’re reading does not need to change. Climbers, guides, and family members of those listed are invited to submit corrections at any time.
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 — this is detailed further in Investigation 03: Operator Power Rankings. Third: climbing without supplemental oxygen more than doubles your risk profile. Across 339 fatalities, 53% 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. This map exists so the climbers who use it can make decisions with the data, not despite it.
