Petrified Ginkgo log, Vantage, Washington
[photo: D. L. Dilley]
This is an unused Smith-Western Co. postcard featuring a
photograph by D.L. Dilley of a large chunk of a petrified ginkgo log. The identifying code: S-74237 is found at the bottom of the center
line on the back of the card. Credit to
Dilley is found at the left corner on the back.
At the upper left on the back of the card is the blurb: “The first Ginkgo log found in the Vantage
Washington Area of the Columbia River.
This log is located in the Ginko Petrified Forest Museum Building.
Also sometimes called the maidenhair tree, ginkgo trees are known to
have existed since the time of the dinosaurs or earlier in East Asia. The tree was cultivated in early human
history and commonly grown as a landscape plant today. It is regarded as a living fossil. It is a tall, long-lived tree with fan shaped
leaves.
Just looking at this picture of a piece of petrified wood on
the card, it is hard to imagine what the actual tree looked like when it was
living. There is a ginkgo tree Bob and I
often pass when taking walks. I took some
pictures of the tree and its distinctive leaves. Young ginkgo trees are slender and sparsely
branched. As the tree ages it fills out
and broadens. The tree is insect and
disease resistant. Some living ginkgo trees are
estimated to be more than 3,500 years old.
Based on the age of many of the houses in the area where this tree is
growing, it is probably close to 70 to 80 years old, hence very young for a
ginkgo.

The Ginkgo Petrified Forest State Park found at Vantage, Washington
is a geologic preserve and recreation area on the western shoreline of the
Columbia River’s Wanapum Reservoir. This
area was home to the Wanapum tribe of Native Americans. Fishing and agriculture were what sustained
their living. They carved
petroglyphs in the basalt cliffs and may have used some of the petrified
material for tools or arrowheads. The
Wanapum people welcomed white strangers during Lewis and Clark’s expeditions during the early 1800s. Unfortunately, since they did not sign any
treaties with the new settlers who arrived later, they retained no federally
recognized right to the land. In 1963
when the Wanapum Dam was completed the water level of the Columbia River rose. A new Interpretive Center was built and about
60 of the approximately 300 petroglyphs were salvaged from the rising water. Many of them are now on display at the Interpretive
Center.
The geologist and teacher at what became Central Washington
University, George F. Beck, was asked to organize excavations after highway
workers noticed petrified wood in this area in 1927. In addition to ginkgo several other petrified
specimens were found, such as, Douglas fir, walnut, cottonwood, magnolia,
madrone, sassafras, yew, redwood, sweetgum, and witch hazel. A small museum was built by The Civilian Conservation
Corps at Vantage and opened to the public in 1938. Known as a “desert rat,” Frank Walter Bobo who
had been digging petrified logs in Yakima and Kittitas Counties, was then commissioned
to collect, saw, and polish specimens for the museum. He was allowed to keep half of the specimens
he prepared as partial compensation.
After he passed away his son, Don J. Bobo, inherited his father’s
collection of about a ton of petrified wood.
The park has been a U.S. National Natural Landmark since 1965. Petrified wood was named as the Washington
state gem in 1975.
Dennis Lee Dilley (1932-2019) was a color photographer and
artist whose work can be found on chrome-era postcards across the Pacific Northwest. His photographs include locations like of the
Grand Coulee Dam, the Whitman Mission, and this one from the Ginkgo Petrified
Forest. His works were distributed by
the Smith-Western Co., of Tacoma, Washington.
