- Ginkgo Petrified Forest State Park History (parks.wa.gov)
Ginkgo Petrified Forest State Park preserves a swath of semi-arid shrub-steppe in central Washington that hides a secret. Buried within the gravelly and sandy soils of the park’s landscape are remnants of an ancient forest, turned to stone by a fortunate convergence of geologic events.

Ginkgo Petrified Forest State Park/Wanapum Recreational Area is a geologic preserve and public recreation area covering 7,124-acre (2,883 ha) on the western shoreline of the Columbia River’s Wanapum Reservoir at Vantage, Washington. Petrified wood was discovered in the region in the early 1930s, which led to creation of the state park as a national historic preserve. Over 50 species are found petrified at the site, including ginkgo, sweetgum, redwood, Douglas-fir, walnut, spruce, elm, maple, horse chestnut, cottonwood, magnolia, madrone, sassafras, yew, and witch hazel.
