The Crack Climber’s Technique Manual

Whether your goal is to be the rope gun at Indian Creek, swing leads on
Astroman, or improve and expand your current skills, this comprehensive work
goes well beyond other instructional resources, both in scope and detail.
Written by a true master of crack climbing, this book takes an engineer’s
approach to the mechanics of jamming and combines it with detailed, realistic
illustrations.

The result will have you climbing cracks with the finesse and efficiency that
takes most years to master. The author, fondly known among his friends as “The
Sender,” has hundreds of first ascents of difficult desert cracks to his
credit. Take advantage of his tremendous experience and the secrets he
reveals, and you will soon be enjoying those cracks you now avoid.
