The End Is Near!
Just thought I’d throw that in. There have been so many technological advances since the mid-1800’s that it truly boggles the mind. Scientific advances seem to have been exponentially multiplied in all fields.
And in other fields, new artifacts are being found that the technological advances “somehow” seem to match...I wonder why that is...?
The obsidian trade goes back a long way, this technology is likely to find samples from previously unknown sources.
