Ever wondered what it would be like to trudge through the remnants of an ancient forest? To be able to touch a memory of the past and take in the splendor of our planet. Well, you’re in luck, because California is home to one of the largest and oldest petrified trees in the world; a glimpse into how Earth’s environment looked millions of years ago.  Get ready to jump into a time machine and enjoy one of the coolest sights to see in California’s forests. So where to get started?

The Origins of The Petrified Forest

Fossilized state of the ancient redwood trees found in the petrified forest, a true relic of the past.

The term “petrified forest” doesn’t exactly appear in our everyday vocabulary, as it’s quite a rare phenomenon. What exactly is it? To put it simply, petrified forests are ancient trees that have been fossilized due to natural disasters occurring at the time. They are essentially a very well-preserved set of trees from ancient times. The petrified forest found in Calistoga, California is the result of the volcanic activity of the now extinct volcano called Mt. St. Helena. When this volcano erupted millions of years ago, the thick volcanic ashes that reached the forest buried the trees under them, rendering the area devoid of oxygen and causing the accumulated water to evaporate from the wood. This phenomenon allows the void spaces and pores of the trees to be filled up and turn the wood into stone, hence the fossilized state of the trees.

This petrified forest was buried for an estimated 3.4 million years until it was discovered by Swedish homesteader Charles Evans in 1870, which then led to scientists arriving at the site to examine this peculiar finding. The trees were identified as ancient Redwood trees and were used as grounds to carry out studies of prehistoric fossil records. Throughout the years, petrified Oak and Pine trees were also discovered around the area.

Directions to the Petrified Forest

Finding the forest is relatively easy, you just have to drive up the windy Calistoga road and the signs will lead you to it. Once you reach your destination, you will see a house that has been renovated into a gift shop where you can purchase your ticket to start your adventure. The admission fee varies from $12 for adults to $6 for children over 6. Once you’ve purchased your tickets you will be given a map of the forest to help you navigate yourself and discover the ancient petrified forest.
