John Day Fossil Beds National Monument is a 14,000- acre (5,700 ha) park in eastern Oregon. Located within the John Day River Basin, this U.S. National Monument is world renowned for its well preserved, remarkably complete record of fossil plants and animals, a record that spans more than 40 of the 65 million years of the Cenozoic Era (also known as the Age of Mammals and Flowering Plants). The monument is divided into three units: Painted Hills (named for the delicately colored stratifications) northwest of Mitchell, Sheep Rock which is northwest of Dayville, and Clarno which is 20 miles (32 km) west of Fossil. Blue Basin is a volcanic ash bowl transformed into claystone by eons of erosion, colored pastel blue by minerals.
