I summited Everest on May 21, 2011 and have climbed it three other times (all from Nepal) - 2002, 2003 and 2008 each time reaching just below the Balcony around 27,500' (8400 meters) before health, weather or my own judgment caused me to turn back. I attempted Lhotse twice - 2015 and 2016. When not climbing, I cover the Everest season from my home in Colorado as I did for the 2004, 2005, 2006, 2007, 2009, 2010, 2012, 2013, 2014, 2015, 2016 , 2017, 2018, 2019, a virtual 2020 season, 2021, 2022, 2023, 2024 and now the 2025

Overview

The north side of Everest is steeped in history with multiple attempts throughout the 1920's and 1930's. The first attempt was by a British team in 1921. Mallory led a small team to be the first human to set foot on the mountains flanks by climbing up to the North Col (7003m).  The second expedition, that of 1922  reached 27,300' before turning back, and was the first team to use supplemental oxygen. It was also on this expedition that the first deaths were reported when an avalanche killed seven Sherpas.

The 1924 British expedition with George Mallory and Andrew Sandy Irvine is most notable for the mystery of whether they summited or not. If they did summit, that would precede Tenzing and Hilary by 29 years. Mallory's body was found in 1999 but there was no proof that he died going up or coming down thus the importance of finding the camera and potential photos of a summit.

It was a Chinese team who made the first summit from Tibet on May 25, 1960.  Nawang Gombu (Tibetan) and Chinese Chu Yin-Hau and Wang Fu-zhou who is said to have climbed the Second Step in his sock feet, claimed the honor. However without a summit photo, many doubted the summit claim. In 1975, a successful summit was claimed by the Chinese when the ladder on the Second Step was installed.

Tibet was closed to foreigners from 1950 to 1980 preventing any further attempts until a Japanese team summited in 1980 via the Hornbein Couloir on the North Face.

But it is who summited first that dominates Everest folklore. Was it Mallory and Irvin in 1924, or Tenzing and Hillary as we know in 1953. Some even speculate it was British climber, Maurice Wilson in 1933

With the mystery dominating Everest gossip for almost a century, teams have looked in vain for positive proof of a 1924 summit. There have been valiant efforts throughout the years. In 1933, Irvine's wooden ice axe was found in the fall line of the climber's last known route. A Chinese porter reported seeing an "english dead" in 1960 but there were no pictures.

Then in 1999, a team led by IMG founder Eric Simonson conducted a serious search. Conrad Anker found Mallory's body on the north side below the Chinese reported location. Neither Irvine's body nor the camera was located. Simonson returned in 2001 to look for the camera, without success. It was the classic needle in the haystack search complicated by snow cover.

While the discovery of Mallory's body created excitement throughout the climbing world, it did not provide any evidence of a summit. In fact it just fueled the speculation. Everest historian, Tom Hozel has studied images of the area and feels he knows where the Irvine's body is located. He is seeking sponsors for an expedition.

Recent Events

China closed everest citing COVID in 2020,21 and 22. They were late issuing visas in 2023 thus no westerners climbed, only a Chinese science team. A 7.8 magnitude earthquake in Nepal on April 25 caused the Chinese to close Everest in mid season resulting in no summits from the Tibet side in the Spring of 2015. The Chinese have been diligent to remove visible dead bodies from the Northeast Ridge route since 2012 including Tsewang Paljor, aka "Green Boots" at 8500 meters. The last few seasons, up to 2019, have been normal with a couple of deaths each year and some without. There has been a steady increase in the number of climbers. The Chinese are establishing more rules to address the growing crowds, trash and bodies. In late 2019 they increase the permit fees significantly.

In December, 2020 Nepal and China jointly announced a new measurement of Everest. Taking several years and using historic (theodolite) and modern (satellite, GPS and radar) methods a new height was changed to 29,031.69-feet or 8848.86-meters. This was adopted by both counties but not by all organizations worldwide who still use 29,031'/8848m.

The 2024 season was more normal with 74 total summits.

Statistics Updated through December 2024

The Himalayan Database reports that through December 2024, there have been 12,884 summits of Everest through December 2024, on all routes by 7,269 different people. Those climbers who have summited multiple times include 1,670 members and 2,003 Sherpa, for 4,620 total summits. There have been 962 summits by women members.

Summits
The Nepal side is more popular, with 9,156 summits compared to 3,728 summits from the Tibet side. Only 229 climbers summited without supplemental oxygen through December 2024, about 1.7%. Only 35 climbers have traversed from one side to the other. Member summit success stands at 39%, with 5,899 who attempted to summit, making it out of 14,496 who tried. About 66% of all expeditions put at least one member on the summit. Few climbers have summited from both Nepal and Tibet, totaling only 681. Even fewer, 155, have summited more than once in a single season.

Almost all Sherpas, 78, have summited within seven days of their first summit that season. Kami Rita Sherpa (Thami) holds the record for most summits at 31, with Paswang Dawa (PA Dawa) Sherpa of Pangboche close behind with 27 summits. Brit Kenton Cool has 18 for a non-Sherpa record. Eleven Sherpas have 20 or more summits. One hundred and one Sherpas have summited Everest 10 or more times. Member climbers from the USA have the most country member summits at 1,078, followed by China at 683, India at 605, and the UK at 560.

Deaths
As for Everest deaths, 335 people (203 Westerners and 129 Sherpas) died from 1922 to December 2024. These deaths account for about 2.7% of those who summited, resulting in a death rate of 1.11% among those who attempted to reach the summit. Westerners die at a higher rate of 1.36%, compared to Sherpas at 0.84%. Descending from the summit is deadly, with 74 deaths, or 22% of the total fatalities. Female climbers have a lower death rate of 0.81% compared to 1.14% for male climbers, and 14 women have died on Everest.

The Nepalese side has seen 9,156 summits with 225 deaths through December 2024, or 2.5%, representing a rate of 1.12%. One hundred thirty deaths, or 27%, did not use oxygen. The Tibet side has witnessed 3,728 summits with 98 deaths through December 2024, or 2.6%, a rate of 0.98%. Thirty-eight individuals died without using oxygen. Countries with the most deaths among climbers include India at 28, the UK (19), Japan (19), the US (17), and China (12), with South Korea at 11. Nepal has the absolute highest number of deaths at 135, dominated by Sherpas. Most bodies remain on the mountain, but China has removed many from view on its side. The top causes of death are avalanches (77), falls (75), altitude sickness (45), and exposure (26).

Latest: Spring 2024
In 2024, 861 summits were made, including 74 from Tibet and 787 from Nepal. All but 5 used supplemental oxygen. 77% of all attempts by members were successful. Of the total, 73 females summited. The Tibet side saw a 67% summit rate compared to 68% on the Nepal side. Eight Everest climbers died.

Everest compared to Other 8000ers
Everest is becoming safer even though more people are now climbing. From 1923 to 1999, 170 people died on Everest with 1,170 summits, or 14.5%. But the deaths drastically declined from 2000 to 2024, with 11,714 summits and 165 deaths, or 1.4%. However, four years skewed the death rates, with 17 in 2014, 14 in 2015, 11 in 2019, and a record 18 in 2023. The reduction in deaths is primarily due to significantly higher Sherpa support ratios, improved supplemental oxygen at higher flow rates (up to 8 lpm), better gear, accurate weather forecasting, and more people climbing with commercial operations.

Of the 8,000-meter peaks, Everest has the highest absolute number of deaths (member and hired) at 335 but ranks near the bottom with a death rate of 1.11. Annapurna is the most deadly 8,000er, with one death for about every fifteen summits (73:514) or a 3.30 death rate. Cho Oyu is the safest, with 4,158 summits and 52 deaths, or a death rate of 0.54, with Lhotse next at 0.61. Of note, 81 Everest member climbers out of 206 member deaths died descending from the summit, or 39%. K2's death rate has fallen dramatically from the historic 1:4 to around 1:8, primarily due to more commercial expeditions with large Sherpa support ratios.

Base Camp (17,000/5666m) to Advanced Base Camp (ABC)(21,300'/6400m)

From BC to ABC it is about 12 miles (22km) of rugged hiking on boulders, ice and snow. The route follows the Rongbuk Glacier until it merges with the Eastern Rongbuk Glacier. ABC is on the northwestern side moraine of East Rongbuk Glacier, under the slopes of Changtse Mountain.

It normally takes 2 days for the first trip to ABC stopping at an interim camp. Once acclimatized, the trek takes 1 day. ABC is the primary High Camp home for Northeast Ridge climbers during the expedition. Climbers use the lower base camp for rest and preparation prior to their summit bid.

ABC to North Col (Camp 1)

(23,000'/7000m) The North Col camp is a 2,200' climb from ABC. Leaving Camp 1, climbers reach the East Rongbuk Glacier and put on their crampons for the first time. After a short walk, they clip into the fixed rope.

The climb from ABC to the North Col steadily gains altitude with one steep section of 60 degrees that will feel vertical. Climbers are clipped into the fixed rope and use their ascenders. Rappelling is used to descend this section. A few ladders may be placed over deep crevasses.

It takes between 4 to 7 hours to reach the North Col depending on acclimatizing and weather.

Camp 1 to Camp 2

(24,750'/7500m) C2 starts the "High Camps". The route is usually pure snow but can be rock since this section is known for high winds.
It should take about 3 to 5 hours to reach C2. Some teams use this as their highest camp for acclimatization purposes.

Camp 2 to Camp 3 (25,600'/7900m)

Some expeditions do not use a Camp 3 and go directly to 8300 m. At almost 8000m, most climbers now sleep on supplemental oxygen.

The climb is extremely windy and the tents are on small rock ledges since there is limited large and level areas. At Camp 3, the wind is usually blocked by the North Face of Everest so sleeping is easier. Climbers will take 3 to 6 hours to reach C3.

This is equivalent to the South Col in altitude and exposure to the weather.

Camp 3 to Camp 4 (27,390'/8300m)

Camp 4 (or Camp 3 if the previous camp is skipped) is a short rest stop on the way to the summit for most climbers. At 27,390', you do not want to spend a lot of time here. Climbers will have some food and water, perhaps a short nap and start for the summit around 10:00PM.

Leaving C3, climbers follow the fixed rope through a snow filled gully; part of the Yellow Band. From here, climbers take a small ramp and reach the northeast ridge proper.

The Northeast Ridge is a few hundred feet above C4.

Camp 4 to 2nd Step

The Northeast Ridge represents the most difficult climbing on this route. There are three "steps" or rock climbs along
the way.

The 1st Step, the first of three rock features, is difficult at this altitude. The route tends to cross to the right of the high point. Some climbers may rate it as steep and challenging. It requires hard pulling on the fixed ropes in the final gully to the ridge.

Mushroom rock is a feature on the Ridge that spotters and climbers can use to measure their progress on summit night. Oxygen is swapped here. The route can be full of loose rock adding to the difficulty with crampons.

The 2nd step is the crux of the climb with the Chinese Ladder. Climbers must first climb about 10' of rock slab then climb the near vertical 30' ladder. This section is very exposed with a 10,000' vertical drop.

It is more difficult to navigate on the descent since you cannot see your feet placement on the ladder rungs.This brief section is notorious for long delays thus increasing the chance of frostbite or AMS.

Second Step to Summit

The 3rd Step is another straight forward rock climb but challenging at this altitude (nothing is easy anymore). Climbers now spend the next hour to climb the steep snowfields of the Summit Pyramid.

It is a steep snow slope, often windy and extremely cold, climbers feel very exposed.  Towards the top of the Pyramid, climbers are extremely exposed again as they navigate around a large outcropping and experience three more small rock steps on a ramp before the final ridge climb to the summit.

The Summit Ridge is the final 500' horizontal distance along the ridge to the summit and is quite exposed. Slope angle range from 30 to 60 degrees. It is narrow with 10,000' drop-offs on both sides leading directly to the Everest Summit.

Now the climbers have spent 8 to 10 hours to summit.  It will take another 4 to 6 to return to C3.
