"I'm quite doubtful if I shall be fit enough. But again I wonder if the monsoon will give us a chance. I don't want to get caught, but our three-day scheme from the Chang La will give the monsoon a good chance. We shall be going up again the day after tomorrow. Six days to the top from this camp!"

--from George Mallory's last letter to his wife prior to disappearing on Mt. Everest with his partner Andrew "Sandy" Irvine in 1924

"My face is in perfect agony. Have prepared two oxygen apparatus for our start tomorrow morning".

1953: British Expedition and FIRST SUMMIT. Led by Colonel John Hunt and consisting of climbers Dr. R.C. Evans, G. Band, T. Bourdillon, A. Gregory, Edmund Hillary, W.G. Lowe, C. Noyce, M.P. Ward, M. Westmacott, and C.G. Wylie. Returning as Sirdar from the Swiss attempts is yet again Tenzing Norgay. The route through the Icefall is completed by April 22, Camp VI is established at the foot of the Lhotse face at 23,000 feet (7000 meters), and after a lengthy delay, the South Col is reached via the Lhotse Face route pioneered by the Swiss the year before.

May 26: First Assault by Evans and Bourdillon from the South Col using closed-circuit oxygen sets. The same day Hunt leads a party of Sherpas from the South Col with the intent to establish Camp IX on the SE Ridge for the second assault party consisting of Hillary and Tenzing. Evans and Bourdillon reach the South Summit at 1 PM at an elevation of 28,750 feet (8770 meters), but are forced to descend due to the lateness of the hour, strong winds, and lack of oxygen.

May 29: Second Assault by Hillary and Tenzing using open-circuit oxygen sets. They leave Camp IX at approximately 27,900 feet (8500 meters) by 6:30 AM, and reach the S. Summit by 9 AM. After negotiating the 40 foot (12 meter) Hillary Step, they are the first to reach the summit of Everest, reaching the top at 11:30 AM. After descending to the South Col, they are met by George Lowe where Hillary states: "Well, George, we knocked the bastard off!"

1955: The height of Everest is adjusted by 26 feet to 29,028 feet (8848 meters).

1956: Swiss Everest/Lhotse Expedition led by A. Eggler with W. Diehl, H. Grimm, Dr E. Leuchtold, F. Luchsinger, J. Marmet, F. Muller, E. Reiss, A. Reist, E. Schmied, H. Von Gunten and Sirdar Pasang Dawa Lama. The South Col was reached by the middle of May, and a successful summit bid was done on Lhotse via the very difficult North ridge on May 18 by Reiss and Von Gunten. On May 23 from a high camp at 27,500 feet (8400 meters) on the SE Ridge, Schmied and Marmet also reach the summit.

1958: Joint Chinese/Russian reconnaissance from the North that reaches 21,000 feet (6,400 meters) below the North Col. The plan was for the two countries to return later for a joint assault, but this expedition never materialized after relations between the two states deteriorate.

1960: Chinese and Tibetan team of 214 men and women, led by Shih Chan- chun, makes the first summit of Everest via the North Col and Northeast Ridge. Long doubted by Western mountaineers because of the lack of a summit photo and the claim of summiting at night, the photos and film the Chinese did release reveal that they at least climbed the Second Step, the key to the route (although Reinhold Messner claims he possesses documentation proving they didn't climb it, so far this evidence has not been produced). The final assault party of Wang Fu-chou, Liu Lien-man, Chu Yin-hua, and the Tibetan Gonbu (also known as Gonpa) assaulted the final 15 foot (5 meter) Second Step headwall using pitons and team tactics. After Liu Lien- man repeatedly falls off attempting to lead the pitch, Chu Yin-hua takes off his boots and socks, and using a shoulder stand climbs the last vertical pitch in bare feet! Exhausted by his effort, Liu Lien- man is forced to halt at 28,600 feet (8,700 meters), but the remaining three climbers make it to the summit where they purportedly leave a plaster bust of Chairman Mao by a rock outcrop.

1960: First Indian Expedition led by Brigadier G. Singh. Climbers Capt. N. Kumar, Sonam Gyatso, and Sherpa Nawang Gombu reach 28,300 feet (8625 meters) just below the South Summit before retreating in a violent storm and driving snow.

1962: Illegal four-man expedition led by the American Woodrow Wilson Sayre following the pre-war British route up the North Col and NE Ridge. Possessing a permit to climb Gyanchung Kang from the Nepalese side, the party ascends the Ngozumpa Icefall with Sherpa support, but then surreptitiously crosses the Nup La into Tibet. Without porters and relying on a grueling schedule of load-shuttling that covers the same ground three times daily, the group reaches the base of the North Col in nineteen days. They climb the North Col, but a fall lands Sayre and partner Roger Hart in a crevasse where they survive the night by wrapping themselves up in a tent. Undeterred, Sayre and Norman Hansen set off the very next day up the North Ridge, but can only climb 1,200 feet (400 meters) in the next two days. Realizing that they are beaten, they turn back but Sayre slips and falls 600 feet (200 meters) down the North Ridge snowfield before stopping. Incredibly, the now emaciated and half-starved expedition is able to return back over the Nup La into Nepal without encountering Chinese patrols.

1962: Second Indian Expedition with Major John Dias as leader. Returning to the SE Ridge route, climbers Sonam Gyatso, Hari Dang, and Mohan Kohli are forced to retreat from a high point of 28,600 feet (8720 meters) because of bad weather.

2019 Searches and Evidence that Irvine and the Camera Were Found by the Chinese in 1975?

Along with Mark Synnott, Thom Pollard was part of the National Geographic 2019 search, as well as a member of the 1999 search that found Mallory's body. I recommend his Facebook page as well as his YouTube channel where he has been producing videos dealing with the new theories that are given below.

After his book "The Third Pole: Mystery, Obsession, and Death on Mount Everest" was published, Synnott uncovered resarch that seems to prove that Irvine and the camera were found by the Chinese back in 1975.

Let's not forget that Jake Norton was on a Discovery Channel search at the same time, but looking in a different place!

There were two films produced about these searches, and you can watch them here: Pollard/Synnott movie "Lost on Everest (Discovery+), and the Norton film Everest's Greatest Mystery (this is an Amazon Prime link, but the movie is available on AppleTV as well).

New Theories

It has recently come to my attention the theories of Ajay Dandekar, a historian and a faculty member of Shiv Nadar University, Delhi. I find his theory that Irvine stayed behind in a sleeping bag while Mallory went to the summit to be highly questionable. Please see my two part series on why I think this is true: Part 1 and Part 2

He's been around for awhile, but you'll want to read Michael Tracy's thoughts of what happened to Mallory and Irvine, along with his repository of YouTube videos. He's very mercurial and you'll need a thick hide if you debate him!

New Mallory and Irvine Forum hosted by Jake Norton

Please visit and become a member of Jake Norton's new Mallory and Irvine forum. You'll want to check out his image-based collection of all of the searches for Irvine from 1999 to 2019. He also has a three part series on his theory of what happened to Mallory and Irvine: part 1, part 2, part 3. And finally, here is the link to his Mallory and Irvine archive.

Articles and Editorials

A new article by researcher Wim Kohsiek, who has convincingly interpreted the time Mallory's watch was pointing to when it stopped, at odds with Jochen Hemmleb's interpretation that it was pointing to the time of Odell's sighting of the pair at 12:50 pm.

An interview with Graham Hoyland, author of the new book “Last Hours on Everest - The gripping story of Mallory and Irvine's fatal ascent”

Harvey V. Lankford, MD, has written a paper documenting the origin of the term "Glacier Lassitude" as a diagnosis for the debilitating effect of altitude as experienced by members of the early British Everest expeditions.

My new "what if?" theory about Mallory and Irvine's last climb, where I assume Odell's sighting was erroneous, and have them taking the Couloir route instead.

Part 1: the ascent
Part 2: the descent

Warwick Pryce is a new researcher who has arrived on the scene, and he has a new theory about how Andrew Irvine could have been the first person to stand on the top of the world.

Wim Kohsiek has a new interpretation of what Mallory's altimeter can tell us based on scientific applications of meterology.

Mallory and Irvine researcher Wim Kohsiek has two new thought-provoking articles about Mallory's watch and Irvine's location:

• Does Mallory's watch point to the time of his death?
  
  
• Where is Irvine?
