Everest from Pumori

Everest, malady Lhotse and Nuptse from Pumori Camp 1

For those who love Everest, the arrival of the official summit numbers is always a milestone. The Himalayan Database was updated with the latest summit statistics on February 14, 2014 – a nice valentines gift!

The Database contains the summit records for almost all of the Himalayan peaks located in Nepal and Tibet from 1905 to present day. It is maintained by a small team of devotees lead by the legendary Ms. Elizabeth Hawley out of Kathmandu. See this wonderful video interview of her.

I last met her during my 2013 Manaslu climb. You can read about it here. As I have mentioned many times, meeting with Ms. Hawley is a highlight, and a stress point, of each expedition.

Ms-Elizabeth-Hawley-workingShe arrives at your hotel with clipboard in hand asking about your occupation, intended route, anything special about your team. Upon your return she repeats the grilling with questions on your summit. If you don’t meet her high standards, she will not put you in the database as a summiter!

She is ably assisted by several individuals including Billi Bierling and Richard Salisbury, who based in the US, does all the database work and administration needed to make the information usable for anyone who s the database for a bargain of $70. There is a bit of a learning curve but once mastered, it offers a wealth of information. Please see this interview I did with Richard last year.

Another excellent source of Himalayan summit numbers is from Eberhard Jurgalski at He covers Pakistan in addition to Nepal.

Everest Overview

As of February 2014, the final 2013 numbers on the Himalayan Database showed that 658 climbers made the summit. There were 539 from the south and 119 from the north side. 9 did not use supplemental oxygen and there were 8 confirmed deaths.

This brings the total summits to be around 6,871 by 4,042 different climbers, meaning that 2,829 climbers, mostly Sherpa, have multiple summits. The south side (Nepal) remains more popular with 4,416 summits while the north (Tibet) has 2,455 summits.

Overall 248 people (161 westerners and 87 Sherpas) have died on Everest from 1921 to 2013, 140 on the Nepal side and 108 from Tibet. Since 1990, the deaths as a percentage of summits have dropped to 3.6% due to better gear, weather forecasting and more people climbing with commercial operations. Annapurna remains the most deadly 8000 meter mountain with three deaths for every summit (211:69) or 32% .

As the chart above shows, the number of summits has been growing rapidly since the early 1990’s when commercialization began lead by Mountain Madness and Adventure Consultants. Note the number of Sherpa who are summiting is also growing faster than the clients, also called members. This is primarily due to commercial operators adding more support, in some cases two Sherpa for each western climber. The drop-off in summits in 2008 was when the Chinese closed the north side for the Beijing Olympics and effectively throttled the south.

There have been 3,220 summits by Sherpa or guides also called “hired” with 53 of those not using supplemental oxygen. 4 were women. This leaves the remaining summits by members at 3,561 and of that 139 were without extra O’s. As for women, Everest has seen 410 female ascents by 372 different women.

Looking at the average deaths since Everest was first attempted in 1921, it is 4.4 each year. Focusing on modern times since 2000 and then 2006 to 2013 it is 5.8 and 6.6 annual deaths respectively. Sadly we can expect this trend to continue as the mountain is attracting more climbers each year, many unprepared.

In the trivia department, the Himalayan database shows

  • 2 true solo ascents
  • 31 traverses
  • 22 ski/snowboard descents
  • 13 Parapente (paragliding) descents
  • 1 unauthorized ascent
  • 19 disputed ascent
  • 15 unrecognized ascents

Fun Facts

I have a section on my main website called Everest for KiDs. It is based on my 2002 attempt of Everest where I did not summit and used in schools around the world to teach students about goal setting, geography and Everest. Part of that section contains Everest Facts for KiDs which follows here:

  1. This is realy great info…for loosing so much callories.
    A lot of women spent a lot of money for loosing some pounds…Everest seems to be a best place for that:)))

  2. Great info Alan!

    I too have and use the Himalayan Dateabase for info and stats for my website. A very good source and a great price!

    Mount Everest The British Story

  3. Hey Alan – fascinating information.
    I think with reference to your statement under the History heading that “The mountain was first identified by a British survey team in 1841.” ignores the centuries of identification by the Tibetans even as the tallest mountain around which lead them to give it that queenly title, Goddess Mother of the Universe. This name dates back at least to the 11th century(according to Rheinhold Messner in The Crystal Horizon, p134) when the famous monk Milarepa wrote a poem about the mountain.
    It may be more correct to say the British first surveyed the mountain since saying they ‘identified’ it gives the false impression that no one had ever noticed the world’s tallest mountain and certainly the tallest mountain amongst the tallest group of mountains in the Himalayas clearly visible from a great distance in Tibet. You may discard my clarification as purely semantical but not recognizing it diminishes the Tibetans and Sherpas and Nepalis, too. In addition to this, the very name Everest applied to this mountain which had been named so long before by the Tibetans, Qomolungma, and was clearly located within countries that the British couldn’t even legally enter at the time, brings up the question of the validity of the name Everest all together. The Chinese do not recognize the name and call it a remnant of colonialism.
    I believe the continued use of the name is a continuing affront to both the Tibetans and the Nepalis. And as respectful travelers in their countries should recognize their names for the mountain which resides in their country not in Britain.

    • Thanks for your perspective and additions Jeff. Clearly the Indigenous people around the globe were the first to spot the highest mountains. In my travels, Australia does a nice job of recognizing the “early visitors” with a plaque near the summit.

  4. Dear Allen,
    I am sorry to have not received any confirmation to my ealier post regarding Fun Facts about Everest. Please oblige me with your reply. I further like to add that although you did mention the male climber’s name with maximum ascent to top but you have missed the name of Lakpa Sherpani of Nepal who climbed maximum number of six times on the top from both sides. I feel that this is also a great feat particularly for women climbers.

  5. Dear Allen,
    Thanks a lot for the detailed analysis on Everest ascents in 2013 & other chronological updates on the Everest Climbing. However i feel that the youngest women climber to have climbed Everest from Tibetan side at 15 years ,Ming Kipa of Nepal on 24th May,2003 is worth mentioning in your list of important summits.

  6. Under Kid Stuff, or Fun Facts…. Didn’t you take Flat Stanley up to the top???? lol

    I can’t believe you didn’t mention him. It is one of my special memories from when my kids were little. As a class a contest they had to track his travels. We took him every single place we went for the entire school year. I think he liked Disney the best.

    Memories are everything

  7. Just out of interest what is the difference between ‘unrecognised ascents’ & ‘disputed ascents’? In respect of Everest what is a Traverse? And finally just who managed an Unauthorised Summit? Did they sneak through the Park Entrance?

    Great stats though.

    • I’ll try on these but the experts at the Himalayan database are the final authority. As I looked through the database, most of these classifications are decades old and only a couple have been used since 2000.

      Unrecognized and Disputed are similar where perhaps fraud might have been involved or they died on the descent (questionable), a climber claimed he/she reached the top but perhaps had no proof (photo, witness, etc.) or died on the descent but no one saw them on the summit. Finally, another climber might successfully argue the other climber did not summit so it is marked as disputed.

      A traverse is starting at one point and ending at another while going over the summit.

      Unauthorized, they had no permit. Yes, people do sneak in; especially on the North.

  8. Great info Alan…

  9. Love, love, love the wealth of information you share, Alan! Thank you SO much !

  10. I was so excited when I met her at the Yak n Yeti. What a treasure! Found a book about her in a bookstore in Kathmandu!
