The Petrified Forest is a petrified forest located in Sonoma County, California, in the United States. It is the only petrified forest in California from the Pliocene. It also has the largest petrified trees in the world. The forest is now open to the public to visit after restoration from damage caused by the Napa and Sonoma fires of 2017.

History
Geological history
Approximately 3.4 million years ago a volcano eruption at Mount St. Helena caused the trees to become petrified. The process took thousands of years to complete. Diane Erwin, from the University of California, Berkeley, stated in 2012, that the petrified forest shows that redwood trees were once located more inland, unlike their contemporary descendants that are primarily coastal. The Palynological Society calls the forest "one of the finest examples in the world of an ancient forest."
19th century
The forest was discovered in 1870 by Othniel Charles Marsh. Marsh determined that the petrified trees were Sequoia langsdorfii from the Sequoia genus. There is also one petrified pine tree in the forest. Robert Louis Stevenson mentioned the forest in his book The Silverado Squatters (1883).
Today
Since the early 20th century, the same Calistoga based family has maintained and operated the forest. The forest was bought by Ollie Orre Bockee, from M.C. Meeker, around 1912. The total purchase cost was $14,000. Bockee continued to purchase surrounding land and acquired a total of 845 acres. Bockee opened the property to tourists around 1914 and charged 50 cents per person. Bockee died in 1950. Her sister became the owner of the property. Bockee's direct descendants maintain it today. It was listed on the California Historical Landmarks list on January 31, 1978. In 2012, the family started to send fossilized pollen samples to the University of California, Berkeley for research.
Many of the petrified trees in the forest have nicknames, including The Queen, which is 8 feet wide and 65 feet long. The Queen was 2,000 years old when the volcano erupted. Additional trees include The Pit Tree and the Giant. There are a cluster of trees named after Ollie Orre Bockee and a tree named after Robert Louis Stevenson.
