Petrified wood was discovered in the region in the early 1930s, which led to creation of the park as a national historic preserve. Ginkgo Petrified Forest is a registered national natural landmark. It is regarded as one of the most unusual fossil forests in the world.

Interpretive Opportunities
The Ginkgo Petrified Forest Interpretive Center offers spectacular views of the Columbia River, Sentinel Gap and surrounding Ice Age flood-carved basalt landscape. Indoor exhibits tell the geologic story of the Vantage Petrified Forest and display one of the most diverse petrified wood collections in North America. Admission is by donation.

The Trees of Stone Interpretive Trailhead, located two miles west of the interpretive center, guides you through an ancient fossil bed with nearly two-dozen petrified logs exposed along this one-mile loop trail. Along the trail you also will find ice-rafted erratics remaining from Ice Age floodwaters thousands of years ago.

The Cove Recreation Area, located one-and-a-half miles south of the Wanapum campground, offers a half-mile, self-guided interpretive trail along Johnston Creek.
