Early Everest Attempts: 1921-1938 by Audrey Salkeld In the early years, little was known about the physiological effects of extreme altitude, and mountaineers the world over wondered if they could possibly climb Mount Everest, the world's highest mountain. It was a leap into the world of the unknown, travelling to far off lands and launching huge expeditions up the slopes of the Himalaya to altitudes no human had ever experienced. Eric Shipton, considered the best mountaineer of his day and a veteran of the expeditions to Everest in the 1930s, predicted that Everest would eventually be climbed, although he was quick to qualify his prediction with commentary on the physiological limitations of high altitude mountaineering: "It would seem almost as though there were a cordon drawn round the upper part of these great peaks beyond which no man may go. The truth, of course, lies in the fact that, at altitudes of 25,000 feet and beyond, the effects of low atmospheric pressure upon the human body are so severe that really difficult mountaineering is impossible and the consequences even of a mild storm may be deadly, that nothing but the most perfect conditions of weather and snow offer the slightest chance of success, and that on the last lap of the climb no party is in a position to choose its day." ![]() A small group of seasoned travellers - one or two mountaineers as well as a few naturalists and surveyors - set off from Darjeeling on May 13th of that year under the leadership of Colonel C.K. Howard-Bury, an Irish aristocrat. The expedition's oxygen expert, Dr. A.M. Kellas, who joined the party in India ![]() After four months of circling and studying Everest, they were within striking distance of setting foot on the mountain itself. After a cold night's camp near the top of Windy Gap, they set off across the East Rongbuk basin with surveyor Wheeler and some porters towards the slopes of the North Col, and began to climb its icy slopes. A gale was raging on top, whipping snow into whirlwinds of deep snow. They took a few steps into it before being forced back. Still to Mallory's experienced eye, the route ahead from there to the summit looked long, but feasible for a fresher party. ![]() In 1924, British mountaineers Norton and Somervell were able to reach a point at 28,128 ft on the North Face without using artificial oxygen. Their effort was quickly followed by another, when Mallory attempted the final ascent with the youngest member of the team, Oxford University student Andrew (`Sandy') Irvine, following the Northeast Ridge line. ![]() They were never seen again, and ever since mountaineers have argued where exactly the pair were when Odell saw them, and whether they might actually have reached the summit ahead of Edmund Hillary and Sherpa Tenzing Norgay, the acknowledged first men to reach the top of this formidable mountain. It remains one of climbing's greatest mysteries. After World War II, Tibet was closed to foreigners by the Dalai Lama, and in 1950 Chinese troops marched in. It would be another thirty years before foreign mountaineers would again be allowed to approach Everest through Tibet, and it was at that time that Chinese parties were successful on the route that George Mallory had been unable to complete.
