Since publication of the first edition in 1961, Mountaineering: The Freedom of the Hills has endured as the classic mountaineering text. Novice climbers use it as a primer veterans use it to review their skills. Translated into five languages, it has instructed and inspired more than half a million climbers from all over the world. The fully updated seventh edition maintains the same high standard for complete, authoritative instruction in an easy to use format. From choosing equipment to how to tie a particular knot, from basic rappelling technique to planning an expedition, it's all here in this essential mountaineering reference. Continued evolution of the sport ensures that climbers who own previous editions will need to upgrade to the new seventh edition. The chapter on aid climbing, for example, has been substantially rewritten to include new aid techniques and equipment. A new chapter has been added to meet the rising popularity of waterfall ice and mixed climbing.
