John Day Stripetigraphy

The John Day Fossil Beds in Eastern Oregon are an amazing fossil locality spanning from the Cretaceous up into the Pliocene - that's 50 million years of nearly continuous fossil history! The rocks out there are preserved in gorgeous bands of color, including creamy yellow sediments of the Hancock Mammal Quarry, oxidized vermillion hues at the Painted Hills, and the brilliant blue-greens of the Turtle Cove member. This pattern is simple, showing the sequence of colors as you go up through time - and I've even got the cross-over between the Kimberly and Upper Turtle Cove on there.
