A solid, concise, and readable treatise on mountaineering hazards, party movement, equipment, safety, technical climbing, glacier travel, rescue, and ethics. The focus is on semi-technical multiday travel over rugged glacier terrain - the segment of climbing were instruction is hardest to find and most necessary. - Backpacker.This book cannot and does not alert you to all the hazards of the mountains. It is a learning tool and should be read and studied as a supplemental source only. It is not a substitute for professional instruction, an experienced mentor, or, most importantly, the wilderness experience itself. If you decide to participate in the activities described in this book, the risk and responsibility for the outcome are solely yours.Powers, Phil is the author of 'Nols Wilderness Mountaineering' with ISBN 9780811730860 and ISBN 0811730867.
