Mudfossil Hunt in Arizona, Day 4. Interesting Pullover Along Road. Giant Tendons and Tendon Balls?

This is from our fourth day of mudfossil hunting in Arizona. We were on our way from one area of the state to another and noticed a sudden change in geology near a little pullover along the road so we whipped off the road into the pullover and jumped out to take a quick look. We did not have time to explore much of it at all. Just a quick run through it. The area was full of standing columns and features that, at first glance, I thought were man-made structures, but were not man-made. I have no doubt we could have spent the day in that area and, in the future, we may be able to return to it.
