This State Park Near Tri-Cities Was Once a Subtropical Jungle, Now it’s Petrified

Not many Washington residents know that the official Washington State gem is petrified wood. And, most people wouldn't know petrified wood is a gem, right? Well, spread over 7,100 acres near the town of Vantage, Washington, you’ll find a truly famous Washington state gem - the Ginkgo Petrified Forest State Park.

The pieces of Petrified Forest in the area are estimated to be about 15.5 million years old, which dates back to the Miocene era.

When one visits the state park now, it’s hard to imagine the area was once a subtropical forest. Over millions of years, trees in the location were covered by sediment and ash from volcanic eruptions and petrified by silicification.

What is silicification?

According to Wikipedia, silicification is a process of petrification involving silica, a fluid that soaks into substances such as wood and rock and preserves them. Silica is a plentiful matter that is found in the Earth’s crust and in other natural materials.
