Allyn, thank you so much. I’ve actually got a creek that runs through my property and have maybe already found something that resembles one of those pieces I saw on the chart.. I put a picture on here back when I found some rocks asking if anyone thought it might be chert. Nobody said anything so I pitched them but I think I stashed the one that might be in the chart.. it was kind of waxy looking when I cracked it into. I might go back out there this weekend and see if I can find it. If I remember right I sat it on a log laying in the creek. Should still be there if it didn’t get washed away by the creek. If I find it I’ll post a picture of it on your thread here.
Thanks again
