This book is a companion to the Swiss photography festival, Alt. +1000, held in Rossinière in the foothills of the Alps. HIGH ALTITUDE features works by contemporary photographers who record mountains in their various and multiple states: spectacular, sublime, domesticated, constructed (even artificial!) and frightening. Artists from around the world, many of whom live far from a mountainous environment, celebrate and challenge deeply rooted myths, and individually interpret this elusive landscape. In addition, well-known photographer Olaf Otto Becker, renowned for his views of Greenland, created a portrait of a natural park close to Rossinière.
