Ginkgo Petrified Forest State Park

Vantage, Washington

4511 Huntzinger Rd

An ancient forest was buried in volcanic ash more than 15 million years ago, and many of the buried trees became petrified and eventually buried under basalt flows. The basalt was scoured away by the great Ice Age Missoula floods, exposing petrified wood from more than 50 species of trees. Highway workers discovered the petrified work, leading to the creation of Ginkgo Petrified Forest State Park.

The park's Trees of Stone Interpretive Trail is a 1.5- or 2.5-mile loop trail that winds across the hillside, passing several exhibits of petrified logs found in the area. The park also features an interpretive center, camping and boat ramps.
