Once again, the unknown area, shown in two photos below, is somewhere in the western part of the United States. Where could it be? Why are some of the rocks so red (besides a slight bit of color enhancement to cancel out the haze)? What is the white unit? What is the basic geology of the area, what are some of the major rock formations, or what is the area known for? Damn, it looks like a river runs through it!
The two photos were taken from an unknown altitude, looking northward, almost exactly two years ago. They could almost form stereo pairs, but don't. This is one of my favorite places in the entire world. (Uh, oh! Did I give it away?)
Btw, if you had to pick one geologic time period for the area, what would you pick?
