Anderson Marsh is comprised of over 1,000 acres of wetlands, oak woodlands, and grasslands. It is located in Lake County, California, on Clear Lake. There are at least 30 Native American archaeological sites located here, some of which are over 14,000 years old. Along with its prehistoric past, Anderson Marsh has a rich history of European settlement- the Grigsby's in the 1850's and the Anderson's in the 1880's.

This book outlines the making of the park, its history, and prehistory. Subsequent chapters weave rich details of the park, such as its flora, fauna, Pomo Indian lifeways, basketry, and mythology into a narrative which takes the reader along each of the four park trails.
