Bodies remain on Mount Everest, particularly above 8,000 m in what climbers call the death zone, because recovery at that altitude is extremely dangerous and often impossible, not because of neglect, and the practice has no bearing on the standard Everest Base Camp trek that stays thousands of metres below that altitude. Mountaineering historians and organizations that track Himalayan expeditions estimate the total death toll on Everest has surpassed 300 since climbing attempts began in the 1920s, a figure that tends to rise most climbing seasons. Mingma Tendi Sherpa, our safety lead, wrote this explainer because the topic comes up often from people researching an Everest Base Camp trek who are unsure how it relates to summit climbing.
The sections below cover what the death zone actually is, why recovery is so difficult, and why this has no bearing on the Base Camp trek itself.

What is the "death zone" on Mount Everest?
The death zone is the altitude above roughly 8,000 m where the air holds too little oxygen to sustain human life for an extended period, regardless of how well acclimatized a climber is. Below that line, a body can adapt to lower oxygen levels over days or weeks of gradual ascent; above it, the body is slowly dying the entire time it's there, and no amount of prior acclimatization changes that fact. Climbers above 8,000 m are working against a clock measured in hours, not days, which is why nearly all Everest deaths occur in this zone rather than lower on the mountain.
Everest's summit sits at 8,849 m, meaning the final push from the highest camp involves hundreds of vertical metres entirely within the death zone. Exhaustion, altitude sickness, falls, and sudden weather changes are the most common causes of death there, often compounding each other during the long summit-day push when climbers are already severely fatigued.
Why aren't bodies recovered from Mount Everest?
Recovering a body from high on Everest, especially from within the death zone, is extremely dangerous and often physically impossible, which is why many remain where they fell, sometimes for decades. Helicopter access is limited at extreme altitude since the air is too thin for most helicopters to safely hover and load a passenger above roughly 6,000 to 7,000 m, so any recovery above that height has to be done by climbers themselves. A manual recovery in the death zone can require a dozen or more climbers, each risking the same fatal conditions that killed the person they're trying to bring down, over a task that can take multiple days even under good weather.
Cost is a real factor too: a high-altitude recovery operation can run into tens of thousands of dollars once helicopter support, additional guides, and specialized equipment are accounted for, and it's rarely something a climbing team can arrange on short notice mid-expedition. For these reasons, many climbing teams and families ultimately choose to leave a body where it is rather than attempt a recovery that could cost additional lives. Over the years, a handful of well-known bodies became informally recognized as landmarks along the standard routes to other climbers passing by, a detail widely reported in mountaineering journalism, though this site does not name or describe any specific individual out of respect for the people involved and their families.
How many people have died on Mount Everest?
Mountaineering historians and organizations that track Himalayan expedition records estimate the total death toll on Everest has surpassed 300 since the first documented attempts in the 1920s, though the exact figure is genuinely difficult to pin down and tends to rise most climbing seasons as new expeditions attempt the summit. Early estimates from the pre-1950s British expeditions are less precisely documented than more recent decades, when expedition permits, government records, and independent mountaineering databases have made tracking more consistent. The history of Everest climbing covers how the mountain went from a handful of expeditions per decade to the much larger commercial climbing season that exists today, which is part of why annual death counts have grown even as safety equipment and weather forecasting have improved.
Deaths cluster heavily around the death zone and the descent from the summit specifically, since exhausted climbers descending after a successful summit push are at their most vulnerable point of the entire expedition. This pattern holds across most published expedition data and is a large part of why experienced guides emphasize turnaround times on summit day as strictly as the ascent itself.
Does this affect the standard Everest Base Camp trek?
No. Everest Base Camp sits at 5,364 m, more than 3,000 vertical metres below the 8,000 m threshold where the death zone begins, and trekkers on the standard Base Camp route never approach the altitude, terrain, or conditions involved in an actual summit attempt. The Everest Base Camp trek that this company runs is a trekking itinerary completed on foot with no climbing rope, supplemental oxygen, or technical mountaineering skill required, and it carries an entirely different risk profile from a summit expedition. Altitude sickness is a real risk on the Base Camp trek and is covered thoroughly in our altitude sickness prevention guide, but it is a manageable risk at trekking altitudes, not the same category of danger that exists in the death zone thousands of metres higher.
Researchers and trekkers looking into this topic sometimes conflate Base Camp trekking with summit climbing because both involve the word "Everest," but the two activities share only a starting point and a mountain name. A Base Camp trekker and a summit climber are doing fundamentally different things, at fundamentally different altitudes, with fundamentally different risks.
FAQ
Common questions
What altitude is the death zone on Everest?+
Above roughly 8,000 m, where the air holds too little oxygen to sustain human life for an extended period no matter how well acclimatized a climber is. Everest's summit at 8,849 m sits well within this zone, meaning the final stretch of any summit attempt is entirely within it.
Why don't climbing teams just remove bodies from Everest?+
Recovery above the death zone is extremely dangerous and can require a dozen or more climbers risking the same conditions that caused the original death, often over multiple days. Helicopters generally can't safely operate much above 6,000 to 7,000 m, so any recovery higher than that has to be done manually, and the cost and risk lead many teams and families to leave a body in place rather than attempt it.
How many people have died climbing Mount Everest?+
Estimates from mountaineering historians and organizations that track Himalayan expeditions put the total past 300 since the 1920s, though the exact figure is hard to pin down precisely and rises most climbing seasons as new expeditions attempt the summit.
Is the Everest Base Camp trek dangerous in the same way as summit climbing?+
No. Base Camp sits at 5,364 m, more than 3,000 vertical metres below the 8,000 m death zone threshold, and the trek involves no climbing rope, supplemental oxygen, or technical mountaineering. Altitude sickness is a real, manageable risk on the trek, covered in our altitude sickness prevention guide, but it's a different category of danger from what exists near the summit.
