Though the work is forty years old, Storer and Tevis remains a valuable sourcebook for those wishing to understand the full nature of an extinction. It's all here: bear biology, relationships with Indians, relationships with Spaniards, stories of famous California Grizzlies, the ~real~ life and time of Grizzly Adams, and more. Whether you are a biologist, a historian, or just an armchair wildlife enthusiast, you will find California Grizzly a fascinating and necessary book.
