I love reading about climbing possibly because the very thought of going near a cliff terrifies me. this collection of harrowing and awful experiences on the mountains reminds me of the reason for that fear - Mountains are dangerous places and even the most experienced can die horribly through bad luck or simple chance. Nevertheless it makes great reading from the safety of your armchair
Brilliant and awe inpiring, especially the older stories - how they conquered mountian without all the modern gadgets and clothes that we have today. Makes me want to go out and do
The description I read here on Goodreads was excellent. It is an excellent book on the early days before everyone and their brother were climbing Mt. Everest. Great stories of life and death adventures.
