In 1968, Wally Herbert and three companions set out from Alaska to walk across the North Pole to Spitzbergen. Illustrated with unpublished photographs, his own account of the trek across the frozen Arctic Ocean is supplemented by personal reflections from his daughter Kari, Ranulph Fiennes, Victor Boyarsky and other polar explorers. The result is a record of an epic journey that, as our ice caps melt, is unlikely ever to be repeated.
