Prehistoric archaeology

Hill known as Sheep Rock in the John Day prehistoric area

I share with you today a few photos I took this week of some prehistoric stonework from the John Day and Kimberly area in central Oregon. The area is incredibly rich with such  terrain and archaeological remains, and is monitored by the John Day Fossil Beds National Monument, a US National Monument in Wheeler and Grant counties  in east-central Oregon. 

A section in the same area known as Cathedral Rock

Located within the John Day River basin, the park is known for its well-preserved layers of fossils and mammals that lived in the region between the late Eocene, about 44 million years ago, and the late Miocene, about 7 million years ago. The monument consists of three geographically separate units: Sheep Rock, Painted Hills, and Clarno.The entire area is characterized by hills, deep ravines, and eroded fossil-bearing rock formations, some of which you can see in these photos. Click on each photo to enlarge and admire better.
