Ginkgo Petrified Forest State Park
Vantage, Washington
Ginkgo Petrified Forest State Park 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.
