Anderson Marsh State Historic Park contains oak woodlands, grass-covered hills, and tule marsh. One of the largest groups of people in prehistoric California, the Southeastern Pomo, knew this land as home. Today, descendants of those people still live nearby. Anderson Marsh's archaeological sites hold clues to the lives of the Pomo. Some sites are over 10,000 years old, making them among the oldest in California. Visitors can also explore the past at the historic Anderson Ranch, with its 19th-century structures.

The parks offers exhibits, tours, and occasional recreational and educational events.

Reverend Samuel Adair and his wife, Florella, were peaceful abolitionists who came to Kansas and settled near Osawatomie, an abolitionist community and a center of conflict during "Bleeding Kansas." The Adair cabin was a station on the Underground Railroad and Florella's half brother, John Brown, used this cabin as his headquarters. The cabin survived the Battle of Osawatomie where John Brown and 30 free-state defenders fought 250 proslavery militia in 1856, and stands on the battle site today. Visitors to the Museum can learn more about the Adairs, John Brown, and others who struggled to survive the border war.
