largest groups of indigenous peoples of the Americas in
pre-Columbian California, lived in the area of present day Anderson

the Pomo people. Some sites are among the oldest found in
California, dated at over 10,000 years old.
John Grigsby homesteaded in 1854 with his family, and built a small
house. Scotsman John Still Anderson, with his wife and six children,
bought the property from Grigsby in 1884, built what is now known as
the Ranch House, and ran a dairy and raised beef cattle. Their
descendants lived in the Ranch House until the 1960s.
The State Historic Park was named after John Still Anderson in 1982
after the State of California acquired the Anderson Marsh.
