One day, Muir set out to explore a huge glacier during a blizzard. Stickeen--an aloof little dog belonging to a fellow traveler--insisted on going along. They become stranded on the glacier. The only way out was over a precarious ice bridge, dangerous for a man and almost impossible for a dog. When, amazingly, they both escape, Stickeen's aloofness is replaced by rapturous adoration for Muir. The author skillfully weaves Muir's own words, the illustrations are extraordinary, and the result is a classic.
