I watched the Russian? guys video also years ago. This lead me to take a few slides of various plants under the microscope.
I tried Western Red Cedar wood
Maple and a fresh stem of Cannabis.
The one that mimics the basalt columns exactly including hexagonal and pentagonal shapes was the fresh cannabis. It being freshly cut the shapes were still clearly visible. The other woods had been dry for years so much harder to see the individual fiber shapes. However they are there just shrivelled up and difficult to see.
Some questions arise "What malicious beings cut down these beautiful trees that supported so much life?"
What tech was used to cut through trees several miles in diameter?
With the cutting of the giant trees and the release of so much water from them, did this cause a flood, sudden sea level rise?
Some say the origin of the word country comes from "Count Tree"
Western Red Wood
Maple
