Washington Petrified Forests-Ginkgo Exotic Forest, George F. Beck

All Faculty Scholarship for the College of the Sciences

Seven years ago we began our study of the Ginkgo Petrified Forest in Central Washington. This is in reality a series of forests occurring at various horizons in the Yakima ( and Wenas?) basalts throughout a vertical range of some 2,000 feet, and in a belt 150 miles long, and 50 miles wide, centering at Vantage on the Columbia River.
