California's only petrified forest, where redwood trees were turned to stone by volcanic ash from an eruption of Mount St. Helena some 3.4 million years ago. The largest petrified tree on display is over 30 metres long. A short loop trail winds through the site, with interpretive signs explaining the geology. It is about a 10-minute drive northwest of town.
