Renowned as one of the world's foremost expedition photographers, Gordon Wiltsie has climbed Himalayan mountains, mushed dogs on the frozen Arctic Ocean, skied in Antarctica, and hacked through the Amazon jungle to photograph the most remote reaches of the planet. For the last three decades he has accompanied many of the great modern explorers-Alex Lowe, Conrad Anker, Will Steger, Jon Krakauer, David Breashears, Norman Vaughan-on incredibly challenging climbs and epic adventures. Despite carrying his own share of the weight-along with cameras, film, and lenses-he has matched these companions pitch for pitch and mile for mile, photographing them every inch of the way.

In this journey through ten unique expeditions, Wiltsie illustrates the daily life of an explorer-from the thrill of summiting a virgin peak to the fear of surviving a storm, to the humorous and unexpected everyday moments of life on the edge.
