Actually, there was quite a lot of volcanism in central and eastern Oregon during the Eocene and Oligocene. The Crooked River, Wildcat Mountain, and Tower Mountain Calderas have recently been mapped and identified as the eruptive sources that produced the Clarno.

McClaughry 1, Caroline L. Fossil forests have world-wide distribution, commonly preserving mineralized wood that displays vivid hues and complex color patterns. However, the origin of petrified color has received little scientific attention. Color of silicified wood may be influenced by the presence of relict organic matter, but the most significant contribution comes from trace metals.

National Monument in Wheeler and Grant counties in east-central d within the John Day River basin and managed by the National Park Service, the park is known for its well-preserved layers of fossil plants and mammals that lived in the region between the late Eocene, about 45 million years ago, and the late Miocene, about 5 million.

However, their geographic extent is much greater. To the west the Clarno Formation appears as far as the eastern foothills of the Cascades, to the north it extends nearly to the Columbia River and south beyond the Crooked River. Much of the lower part of the formation consists of basalts and rhyolites, extrusive lavas of volcanic origin.
