John Gill has been called the conceptual father of sport climbing. His one-armed front levers and inspired aerial moves radically reinterpreted the sport, showing peers and critics that bouldering is as valid as alpine and big wall climbing, or any other focus of climbers' attention and energy. In this book, Pat Ament, who climbed with Gill at Horse Tooth Reservoir and Flagstaff Mountain, provides rare insight into John Gill the man, and his evolution into a climbing pioneer.
