Not just the show, but the “tell” as well.
It’s a change up here.
In my area it seems there were primarily only a handful of lithics used for flaked tools.
Obsidian, red/brown chert (or jasper..not sure), agate, and basalt.
I’m not sure I could tell where any of it originated unless it was some sort of exotic material unique to a specific area. Interesting how out east everyone seems to know what county/state a particular material came from. Maybe there is more to it than I’m understanding at the moment.
The edge work on those blades are something else! I like all the different materials and they do have their specific areas they come from. Ohio had several types and was easily identified.
