WV creeks in my area are very rich in what is considered a rather poor lithic, Kanawha Black. I can’t help bringing home a bunch of those discarded, expedient, who knows what pieces. Found an old card caroling that is nice for storing and sorting so the Mrs doesn’t get too annoyed.
I think that material is killer, I don't find much black material or artifacts in my area. I mean I have found some but it's one of the rarest of colors for me.
