June 20, Rest day at the John Day Fossil Beds National Monument

We spent the morning, and returned in the afternoon to the John Day Fossil Beds National Monument visitors center.  There were many displays to view.   The climate in the area had changed from tropical jungle, to Hardwood forest, to near desert grass lands over about 45 million years.   Fossils of animals from the different periods were on display.
The record is continuous, punctuated by volcanic events which left hard layers of rock that can be dated to within 10,000 years.

Between visits to the visitor center, I went on a guided hike through Blue Basin.  It’s not blue, it’s really green!  Here are some pictures.
