State highway workers began finding petrified wood in the area as early as 1927. The State purchased this key 10-acre parcel in 1935 and established the Ginkgo Petrified Forest State Park. Crews from the Civilian Conservation Corps began excavations in 1936 and by 1938 had completed the excavations, trails, a small museum and caretaker’s cottage. The State Park opened to the public in 1938. In 1953, the original visitor center/museum was replaced by a new building about 2 miles to the east looking the Columbia River. The park was designated a National Natural Landmark in 1965. By 1975, the park had been expanded to 7,470 acres. Ginkgo is the rarest variety of petrified wood found in the park.
