Ref.#19 7648 ~ Clarno Formation
The Clarno Formation is one of three units of the John Day Fossil Beds National Monument. The Palisades shown here are the most prominent landform and are volcanic lahars, or mudflows, that formed 54-40 million years ago in a lush semi-tropical rainforest environment. As a young boy I attended the OMSI Hancock science camp where we were instructed how to extract genuine fossils. In the mammal fossil beds, I found the jawbone including teeth of an Oreodont (small four-toed horse) personally which I scraped away the volcanic soil, then shellacked it to hold it together. It then went off to be part of the University of Oregon’s collection.
