Mt Rushmore

These faces are seen by rotating the original photo 180 degrees.

Next:

The photo below has some details enhanced for emphasis.

Some other possible faces. These are very speculative, little more than guesses but are designed to show that more faces may be highly eroded and only a few features remain. The face on the right is almost like another aspect of the kingface, one happy and one angry. it may also be designed to be viewed from a different angle. The photo is formed by overlaying 2 MSSS photos of this area, unfortunately the second photo just misses most of the Kingface, starting at its right eye which is the left eye of the second face..

Another possible face, looking right.
