Sanborn did make reference to using a little steno. But that’s a cryptic comment. Ya know, Sanborn began his career as an anthropologist and as a result he must have studied at least some geology.
SO let me throw this in the mix. And this is a very interesting point that relates the copper screen to the granite slabs projecting out of the ground. Back in 1659, the father of modern geology/paleontology, questioned the idea that fossils grew in the ground as asserted by the church. s credited with three of the defining principles of the science of stratigraphy (essentially how this granite was formed); THE LAW OF SUPERPOSITION (maybe reference to the superposition of the K3 cyphertext), principle of original horizontality and the principle of lateral continuity.
Know what this guy’s name was? STENO. His name was Nicolas Steno
