The Story in the Rocks - Southwestern U.S.

I want to post some photos of geological formations from the Southwest that I have taken on trips the last few years. I would like to discuss what is known about how the rocks formed and when, and what processes acted on them between then and now, and what processes exposed them so we can see them today.The formations in this photo are in north central Arizona along a stretch of Hwy 89, south of Navajo Bridge over the Colorado River and north of Cameron.There are 2 more shots that I hope will make this easier to interpret. I think this valley may have had a number of layers volcanic ash-like material deposited that has been eroded leaving these short buttes that are composed of soft non-lithified material that almost looks like it is melting in the occasional summer rains.We have similar looking formations in Oregon around the John Day Fossil Beds. We have had discussions and debate about interpreting photos in several other threads about the flood where we went down a bunch of rabbit holes arguing about minutia of lines, or shadows, that didn't help the discussion progress. I would rather not repeat that. I don't want to spend a bunch of time talking about things that are not supported by the evidence found in the rocks. I want to find out what the evidence tells us.Geology forum please.
