Petrified Wood Polished Round Rock Vantage Washington
This is a gorgeous polished round Petrified Wood piece that has been sliced and polished on one face and is 6.25 inches and by 4.5 inches wide and .36 of an inch thick.
This great piece has tunnels caused by wood boring insects that burrowed through the tree when it was alive, millions of years ago.
This lovely piece of Petrified Wood came from an old collection, self-collected near Vantage, in east-central Washington area in the 1940's or 50's.
Over 50 species of petrified trees have been discovered in this area, including the elusive rare ginkgo, sweetgum, redwood, douglas-fir, walnut, spruce, elm, maple, horse chestnut, cottonwood, magnolia, madrone, sassafras, yew, and witch hazel.
The petrified wood is over 15 million years old, dating back to the Miocene epoch.
The Ginkgo Petrified Forest State Park located near Vantage along the Columbia River. Highway workers first discovered the park's petrified logs in the 1930s. The petrified trees at Ginkgo Petrified Forest includes logs of trees that probably did not grow together, but accumulated in one place due to water transport.
The park actually opened in 1938, and in October 1965, the National Park Service designated the Ginkgo Petrified Forest as a National Natural Landmark.
Petrified Wood formed when a tree died and was quickly buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
