Similar Face carvings in two separate locations in Henry Crater, Group-A and Group-B show how these two locations separated by a few miles hold almost Identical Artifacts with the same directional composition, Each face has their own character features, nose and hair.
Seriously? Once I realized I was supposed to be seeing profiles of faces; I could sorta-kinda see it. However, I would not say it was obvious. Where do these loonies come from?
