Two young cinnamon-colored bear cubs, Chinook and his sister Snookie, grow and explore their Oregon woodland home under the care of their mother. Through episodic adventures—learning to swim, meeting a Ranger’s Boy, encountering predators such as a mountain lion and bobcat, and observing small creatures like tree mice, pack rats, and Douglas squirrels—they discover food, shelter, and the hazards of rivers, fog, and earthquakes. Scenes move between playful mischief, cooperative problem-solving, and moments of danger, weaving natural-history detail into gentle lessons about curiosity, survival, and the rhythms of the forest.
