This book is an informative summary of the natural history, folklore and trail guide of a regional park located west of Thousand Oaks, California. Dr. Maxwell is an archaeologist who has participated in expeditions througout the world, and information on historical Chumash sites is included in this wonderful book. The trail guide can be used to identify plant species for each of the approximately 15 hikes listed. His knowledge of the area may be unsurpased, which makes this book a valuable legacy for the many years he devoted to leading tours of the area. I would highly recommend this book for those living in the area who enjoy hiking and exploring new areas. Tom Hayduk
