These photos were all taken in the 40 mile stretch getting to 4 Corners.
And to put size in perspective, note the VERY tall electric transmission tower in the foreground.
Here is the same rock formation as shown above but from further down the road, so the sun is now directly on it rather than coming from the side. Note that the color is slightly different.
And these were taken about an hour later, as I was driving back towards Cortez.
