Shiretoko, a World Natural Heritage site, is home to a series of mountains over 1,500 meters high. This time, a Canadian living in Hokkaido Prefecture traverses the Shiretoko mountain range over 3 days as autumn arrives. His first destination is Mt. Rausudake, the highest peak on the Shiretoko Peninsula. The grueling climbing route through the wilderness provides him with encounters with rare plants and wildlife. In the changeable autumn weather, what awaits the climber at the summit is a miraculous and mysterious landscape.
