Gingko Petrified Forest State Park
is a 7,124 acre site on the western shoreline of the the Columbia River's Wanapum Reservoir.
In 1965 the National Park Service designated Gingko Petrified Forest State Park, a National Natural Landmark. This status identifies Gingko as one of the country's best examples of biological and geological features.
Over fifty petrified species are found at this park including ginkgo, sweetgum, redwood, Douglas fir, walnut, spruce and elm. This display in the interpretive center shows an example of petrified oak.
Trees of Stone Interpretive Trail is a 1 mile walk which weaves through the petrified logs in their original setting.
In 1960 rising waters behind the dam put the Wanapum petroglyphs in danger. Sixty of the three hundred carvings from the basalt cliff were saved.
