Located in the town of Fossil, an easily accessible digging site is open to the public for a small donation fee. The hillside just behind the baseball field at the Wheeler High School is a productive Fossil fossils bed.

The Wheeler High School fossil bed as well as other John Day Formation fossils were formed over 30 million years ago. At that time there was a moist temperate climate here. The prehistoric lake was surrounded by lush deciduous forest. During the formation of Cascade Mountains, volcanic ash and silt along with leaves, needles, fish, salamanders, and insects were washed into the lake. Over millions of years the sediments had been fossilized, preserving the ancient organic debris.

Over 30 different species of plants have been found here including ones somewhat similar to present day alder, maple, sequoia, oak, ash trees, rose, and hawthorn. Some extinct species can be found as well. The Cascades formation blocked most precipitation, creating a rain-shadow effect. As a result the climate east of the Cascade Mountains become semi-arid. Maple and pine trees only adapted to the dry conditions and today can be found in this area.

The fossil bed was exposed during the Wheeler High School constructions in 1949 and since is open to public access. Almost every rock on the hillside behind the school contains leave impressions. A little bit of digging is needed to exposed shale. Fossilized leaves are hidden inside of the soft rock. Rarely, collectors can find insects, salamanders, seeds, and flowers.

Open the shale piece by splitting the layers with a chisel or strong knife, lightly tapping with a hammer. Hopefully, a whole ancient leaf will be revealed.

There are some tools available on the site to use, but it is suggested to bring your own including a rock pick hammer, trowel, and chisel.
