Anacapa is the second smallest of California's eight Channel Islands, and we now know that humans occupied it for at least 5,500 years during the Historic Period. That was a long time ago! Learn about the tools people made of chert (a sedimentary rock), the fishhooks they fashioned from bone, varieties of harvested shellfish, and a surprising dearth of seagull bones, suggestive of a significant ecosystem shift on the island. This book will immerse you in the mysteries of ancient human life, and teach you why Anacapa is referred to as "Deception" island.
