Did you know that petrified wood is Washington’s official state gem? Considered one of the most diverse fossil forests in North America, Ginkgo Petrified Forest State Park is famous for its rare specimens of petrified Ginkgo tree discovered there in 1932.

Curious? Drive to the park interpretive center and take in the big skies, Columbia River views and outdoor exhibits of petrified wood. Look for evidence of Ice Age floods carved into the walls of the Columbia River Gorge. Then step inside the Ginkgo Petrified Forest Interpretive Center. Not only is it air-conditioned, the museum features more than 30 varieties of petrified wood, including a display of rare ginkgo petrified wood.

Drive the Old Vantage Highway to the Ginkgo "trailside museum," constructed by the Civilian Conservation Corps in the 1930s, and recently updated with a new interpretive exhibit. From here, the Trees of Stone Interpretive Trail winds past more than 20 petrified logs in their original settings. Birders, look for golden eagles, sage thrashers, Say’s phoebes and many other species. Elk and bighorn sheep also frequent this area.

You may want to reserve a campsite at nearby Wanapum Recreation Area so you can cap off a hot day with a refreshing swim or boat float in Wanapum Lake (a reservoir on the Columbia River). Connect your RV, make a picnic under a shady tree, and savor this green oasis. Just make sure you secure your light weight items as this park is known for high winds.
