|Sheep Rock, one of the landmarks in the John Day Fossil Beds National Monument, Grant County (National Park Service photo, negative no. 370).
Below a cap of erosion-resistant basalt, eroded channels lead down throught 1,000 ft of ancient volcanic ash to the John Day River. This ash, now turned to claystone, contains the fossils of plants and animals from 25 million years ago.
Sheep Rock is located 2 mi north of the junction of U.S. Highway 26 and Oregon Highway 19, west of Dayville, close to the John Day Fossil Beds National Monument headquarters at the Cant Ranch on Highway 19.
