Vertical Mosaic. In this book are gathered ten of his outstanding essays, written over a period of twenty-five years. Porter's well-known ex-student Wallace Clement provides the introduction for this volume, and Richard Helmes-Hayes has compiled an updated bibliography of writings by and about John Porter.

John Porter was born in Massachusetts and started climbing at the age of 12, serving his apprenticeship in the White Mountains, Rockies, Cascades and Yosemite. He moved to the UK in the early 1970s to do postgraduate work at Leeds University, where he joined a team of climbers dedicated to clean ethics, alpine-style, and the fostering of international partnerships.

Ascents of the north face of Koh-i-Bandaka (1977) and the south face of Changabang (1978) with Alex MacIntyre and Polish friends were achieved in the middle of the Cold War. Other climbs include lightweight attempts of the west ridge of Everest in winter, the northwest ridge of K2, the east face of Sepu Kangri, first ascents of Chong Kundam I and V in the Eastern Karakoram, and many other notable climbs around the world over a period of 55 years. In 1980 he founded the Kendal Mountain Festival with Brian Hall and Jim Curran, and in 2011 he and Brian founded the adventure-film website SteepEdge.com.

John is a vice-president of the Alpine Club and has previously been a vice-president of the British Mountaineering Council and secretary to the Mountain Heritage Trust. He lives in the Cumbrian Lake District, UK.
