Sheep Rock

Sheep Rock in the John Day Fossil Monument is located in a valley along with a section of the John Day River. The stratified hills in the area reveal the entire mammal history. The site also contains the primary visitor center for the monument. The visitor center has a nice museum containing examples of the fossils found in the hills. A paleontology center is actively used for cleaning and preparing fossils for study. If you have time, you might be able to take a guided ranger tour.

This is a nice stopping point for our son. The center has a lot to explore and there are hiking trails fairly close by. Across the street from the visitors center is the Cant Ranch House - the historical home of one of the original ranching families.

Down the road in Dayville, the Fish House and RV park is a terrific place to spend the night. You can camp, stay in your RV or rent rooms. Dayville also has a few markets and a gas station.

John Day Fossil Monument

The monument is about a four hour drive from Portland. There are three primary sties: Clarno, Sheep Rock and Painted Hills. All of the sites are worth a visit.

Clarno is the site of the fossilized nut beds and mammals. It is adjacent to the Hancock Station (an OMSI educational facility). There are a few short hikes at the Clarno site and the scenery is dominated by basalt palisades.

If you can, joining any of the OMSI programs at Hancock Station will enable you to see much more of the Clarno area than the monument facility will. OMSI offers access to the digging sites.

We enjoyed the hikes and the picnic area. The best part of our visit was speaking with one of the employees of the monument. He was knowledgeable of the area in a way that helped us to make sense of what we were seeing and  very passionate about the history or the flora and fauna. In general, any time we speak to some of the older employees at the national parks and monuments, we have a really great experience.

Bring water, food, any park documentation you can find and wear long pants. The terrain is comfortable for rattlesnakes.

Oregon Rocks

We just returned from a trip to the John Day Fossil Beds Monument. The monument is located in the north-central part of the state of Oregon; about a 5-hour drive from Portland. We like to visit this location because:

- it is a beautiful part of Oregon
- there are not many people
- we like fossils and rocks

On the way out, we stopped in Madras at the Richardson Rock Ranch to hunt and dig for thundereggs. The ranch is quite large (of 20 square miles) and has been in the family for 7 generations. In addition to cattle ranching, the Richardson family allows people to hunt for a variety of rocks. They also sell rocks from around the world.

At first, we had no idea what we were doing. We drove to an area set-up for digging and pulled out our gloves, eye protection and borrowed rock hammers (provided at the ranch). The gloves and eye protection were great to have. Towels and water would have been good, too. Digging was a dusty process.

A knowledgable fellow showed up with his family and helped us to better understand what we were looking for. Thundereggs can have ridges on the outside that indicate the formation of a central agate region that is usually fairly crystalline in appearance. There are also mudballs that contain a lot of small round nodules on the outside and a fairly dense, dark center.  We picked up about 10 pounds of rocks - mostly thundereggs, but also a piece of obsidian and some rose quartz.

We will have to go to the Rice Museum and see if we can have the thundereggs cut open.

In terms of a family event - this was a great way to go. We could have spent the entire day at the ranch - especially if we had brought a lunch. There are several digging sites and the store and museum of interesting. Our son's imagination was running free while we were digging. He formed a rock-hounding partnership with another little boy and they were busy the entire time.

It would be helpful to do some research beforehand to know more about what to look for.
