Is the famed Devils Tower mesa an ancient tree stump?
Can the ancient trees be silicon rather than carbon based? This is rather intriguing, if you like geology and have some grasp of multi-dimensional universe. I like the Electric Universe model in my cosmology, and esoteric studies stipulate a descent in dimensions from that which is silicon crystal matrix to a 3D carbon organic matrix. Thunderbolts Project has some lovely documentaries presenting the impression of the skies viewed by our ancient ancestors on Earth. The visionary context suggested with the inclusion of these perspectives allow for non-trivial contemplation.
I find it rewarding to consider some geological anomalies from this fellows perspective, though I do not feel in alignment with all the ideas presented. Imagine a variant of the biosphere of Pandora from the film Avatar as a depiction of pristine Earth. Before the invasion.
