Hi.

According to the tfes wikia, specifically this article: https://wiki.tfes.org/Samuel_Rowbotham

Mr. Rowbotham says the next:
"But in reference to matter, and material combinations and phenomena, we should be content with nothing less than conviction, the result of special practical experimental investigation."

Since all the TFES theories should be based on experimental evidence, I would like to know what kind of experimental evidence does the TFES have about the Ice Wall.

https://wiki.tfes.org/The_Ice_Wall

What I mean with experimental evidence is not only a recorded video or photograph, but also mathematical calculations of its height, composition, age and evolutive changes over the millennia, what geological process/es contributed to its formation etc.

If you are not able to offer such experimental investigation directly here, please, let me know where I can read about this information WITHIN the TFES literature (not on globe earth essays).

Thank you.
