John Day Fossil Beds encompasses 14,000 acres in three geographically separated units in Oregon: Sheep Rock, Painted Hills, and Clarno. The Sheep Rock Unit is located between the towns of Dayville and Kimberly. The Painted Hills Unit is located 9 miles northwest of of the town of Mitchell. The Clarno Unit is located on Highway 218 twenty miles west of the town of Fossil.
Colorful rock formations at John Day Fossil Beds preserve a world class record of plant and animal evolution, changing climate, and past ecosystems that span over 40 million years. Exhibits and a working lab at the Thomas Condon Paleontology and Visitor Center as well as scenic drives and hikes at all three units allow visitors to explore the prehistoric past of Oregon and see science in action.
