Looks like holes in the Canyon Wall- But when inverted, the holes appear as bumps.

This is a long-known phenomenon. For thousands of years our brains have been accustomed to interpreting solid objects lighted from above (the sun) forming shadows on the objects' undersides, and the opposite for depressions. This has been a common problem among publishers of technical works, printing pictures of moon craters upside down, looking like mesas and viruses particles looking like holes in the background.

I flipped when I saw those two double flipped photos ... In fact, I suddenly realized that I no longer see the end of my nose since my nose just sunk into my face... I will shut my eyes and forget I saw this. Will things ever look right again!! Or, will they look left.

Those are a classic example of the same effect one has to watch out for when viewing 3D paired images looking down on topography. One has to think one's brain back to reality or the ridges and valleys get flipped.
Great pictures.
Great pictures.

Obvious!
But then again something which hitherto I hadn’t considered. Fascinating!

That is so cool, Rick. Just asking: did you see it before you shot it or did you somehow flip the image later and go "WTF'?
