1) "Climbers" M John Harrison
2) "This Game of Ghosts" Joe Simpson
3) complete works of M Twight
I have noticed many climbers favorite climbing books are old classics from the 1930's or whenever. I believe this romantic nostalgism disaffects us from modern climbing and the reality of history. You know, everyone goes to Nepal with "Seven Years in Tibet" and then whines about how much things have changed. Grow up!
That said WH Murray "Mountaineering in Scotland" is a total fucking classic. Ditto "No Picnic on Mt Kenya" Felice Benuzzi. Finally go get "a Climbers Life" by Don Whillans for storys of beer drinking, pub fighting, hard sends, Patagonia, Himalayas and leading 5.11 roof cracks in 1957
