The Coast Salish people inhabited the San Juans for 5,000 years. One important site on San Juan Island, Cattle Point, was a summer camp where residents engaged in fishing and shellfish harvesting. Native peoples' recollections of activities there have been confirmed by physical evidence in the form of shell middens, fish bones, and other artifacts.

Another San Juan site, English Camp, was a winter village site for 2,000 years. Structure remains provide insight into how people's lives and activities changed over time. Tools found at the site have allowed archaeologists to deduce that early residents ate camas bulbs and other plants, engaged in woodworking, weaving, fishing, and carving, and manufactured and used stone tools.

Stein's discussions of the sites and archaeological practices are enhanced by numerous illustrations. Clear photos of different types of artifacts, topographical maps, and other images help the reader to understand how people lived in the San Juans thousands of years ago.
