Found an obsidian point along the Cumberland about 1/ 4th mile behind the house. That had ta travel a ways from the sources in the west.
The material rock and flakes laying on the ground is mind boggling
Almost sensory overload.
I would say half of the debitage is from 100,s of mile away easy.
It ain't native to around here for sure.
They turn it over deep about every 4 or 5 yrs for tobacco.
Found alot of points down there over the years from dalton's to mississippian stuff and everything in between.

Alot of the established knowledge about era,s, distribution, and types is dated. It puts alot of faith into certain people saying this was that, that was this, this was from then or that place.
And 50 60 70 or more years ago.
Not saying it was inaccurate but some saying something carte blanche and everyone accepting it as gospel. Leads to alot of conjecture.
