Stickeen: A Nature Book About John Muir and His Trusty Dog's Adventure;

This true tale actually happened in Alaska to the famous naturalist, John Muir, and it became what he called the most memorable of all his wild days. 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.
