It’s Fun Fact Friday! Here’s some interesting facts for you if you happen to visit John Day Fossil Beds National Monument in Oregon.

In the first photo, that’s the first hill you’ll see that will get your attention as you drive past the sign welcoming you to the Painted Hills Unit. The top of this hill is capped with a volcanic tuff called the Picture Gorge Ignimbrite. This tuff is 28.7 MILLION years old.

The other images show other sides to this same hill as you drive further along the gravel road into the Painted Hills Unit. The red and tan soils are called paleosols, and the red paleosols are indicative of a warmer, wet, tropical to subtropical climate, while the tan soils represent a cooler, drier, more temperate climate.

Those blue-ish shadowed mountains in the background of a couple of the images are the Sutton Mountains.

And now you know!
