The photo above shows the eye-catching Painted Hills Unit in the John Day Fossil Beds National Monument of Oregon. These conspicuous layers represent different claystone deposits laid down about 25 million years ago when this area was a floodplain. Over time, erosion has exposed the ochre, orange and apricot layering. The coloration of the claystone strata seem to change with changing light conditions and moisture levels.
