Everester

The book opens on a happy note. Sir Francis Younghusband, doyen of Everesters, says in his Foreword "Everest is the symbol of the loftiest spiritual height of Man's imagination," a view with which no mountaineer will quarrel since it is the very essence of his creed.

The Snowman definitely exists. The British mountaineers have photographed and measured its tracks. The first European to report the mysterious tracks was the first Everester of them all, Lt. Col. C[harles] K[enneth] Howard-Bury. He startled British scientists in 1921 with the news that his expedition had discovered at 21,000 feet "the track of what was probably a large, loping gray wolf, which had tracks very like those of a barefooted man."

[page 73] When a mountaineer finds a route he can climb, he says it will "go," and he says he can "go."

The only photograph we possessed of the slopes leading to the South Col was a rather unsatisfactory aerial one. It made the upper slopes look impossibly steep. We called it our 'horror photograph', and it was produced whenever one of the party became too optimistic. After perusing it for a while, even the most enthusiastic Everester tended to develop the attitude of: 'Let's go and find we can't climb it! Then we can go away and get down to some really enjoyable exploration!'
