Where was it found? State, side of state like ne/nw/se/sw side of state. Could be a core? but area would help. Other pic's would also help.
I look forward to seeing and having a reference to where.
I stuck the coin in there just to give a better idea of the size. ThanksVery nice core to. Shows good detail on it. I bet if you go back to that spot there might be other things to find.
lcollins, Thank you! the area does make sense (GB) for an Obsidian core. Great find!
