description Painted Hills Overview
The Painted Hills are one of the three units of John Day Fossil Beds National Monument in central Oregon. Their bands of red, gold, black, and gray record changing environmental conditions in ancient floodplain deposits, with the visible colors produced by different minerals and degrees of soil development. The fragile claystone hills are viewed from designated trails and overlooks, while the wider monument preserves fossils documenting ecosystems and climate change over millions of years.
insights Ranking position
Painted Hills ranks #12 of 96 in the Badland ranking, behind Zhangye Danxia Landform, ahead of Dinosaur National Monument.
help Painted Hills FAQ
Why do the Painted Hills have red, yellow, black, and gray stripes?
The bands formed from ancient volcanic ash and floodplain soils that changed chemically under different climates. Red and yellow layers contain iron compounds, while darker bands are associated with manganese and organic material.
When is the best time to photograph the Painted Hills?
The colors often look strongest in soft light after rain, especially during spring when small wildflowers may appear. Late afternoon can also emphasize the red and gold bands, but visitors must remain on the marked trails.
Can visitors walk directly on the Painted Hills?
No, walking on the colored hills is prohibited because the surface is fragile and footprints can remain visible for years. The Painted Hills Unit instead provides short routes such as the Painted Hills Overlook Trail and Painted Cove Trail.
How far are the Painted Hills from the other John Day Fossil Beds units?
The Painted Hills are a separate unit near Mitchell, Oregon, rather than one continuous park with Sheep Rock and Clarno. Driving between the three units takes substantial time, so the National Park Service recommends planning them as distinct stops.
