Painted Hills, Oregon

Part of the John Day Fossil Beds National Monument in Wheeler County, Oregon, the Painted Hills are a kaleidoscopic terrain named after the colorful layers of its hills, which formed when the area was an ancient river floodplain. The striking blood-red layers are due to bands of laterite, or soil types that are rich in iron and aluminum.
