Anderson Marsh State Historic Park

Anderson Marsh State Historic Park preserves a broad tule marsh, varied upland habitats, and one of California’s notably deep cultural landscapes at the southeast corner of Clear Lake. Its 1,065 acres support abundant wildlife, especially birdlife, while also containing archaeological evidence of Southeastern Pomo occupation reaching back more than 10,000 years, with descendants still living nearby. In the American period, John Grigsby homesteaded here in 1854, and after John Still Anderson bought the property in 1884, his family ranch house and cattle operation became part of the site’s historic character. Established as a state historic park in 1982, it remains protected for nature, history, and public recreation.
