Why do the Book Cliffs look like that?

The rocks that make up the Book Cliffs north of Grand Junction once covered the whole valley. Before that, the whole Rocky Mountain region was underwater.
“If we could go back, let's say 10 million years ago, the rocks that are forming that cliff behind me, we would be underneath those rocks because that is an erosional cliff,” said Rex Cole, professor emeritus of geology at Colorado Mesa University and member of the Grand Junction Geological Society.
“Over the last 10 million years, the cliff has been moving off to the north because of erosion,” Cole said.
The shapes created by the slow, but never ending, erosion of the sandstone cliffs bring to mind a collection of books perched on a shelf.

I went to Mt. Garfield Middle School when I was a kid. We went up to the top of the Bookcliffs on a field trip when I was in the 7th grade, and got to see the wave ripples from the primordial sea embedded in the sandstone. I still remember it like it was yesterday. Thank you for the video!
Driving between Green River, Utah and Price, Utah, there are lots of small hills on both sides of the highway. You can see evidence that the area was once underwater, because of all the thin terraces in theses hills. You forgot to mention that the Book Cliffs are the longest continuous escarpment in the world. It goes all the way from Colorado to central Utah.

I thought this was gonna be about all the trash the homeless people leave out there way to thought a discarded camper in the thumb nail :(
Didn't hear anything on ANY Catastrophic events. Typical.
I left a comment about that, too, in a different format. Hope you will read it and enjoy a more realistic version of events.
It’s a 4 minute clip. Relax
