I have just found a very large source of common opal. It’s quite crazed and freeze-cracked but I’ve gotten a few points out of it. If I ever find some purer stuff I’ll slab it and put it in the trade blanket thread. Does anyone know of any historical evidence that opal was knapped by the Old Guys?

Yes, it was knapped bu the old guys.  In the Texas panhandle we have common opal in the caliche and it was used occasionally for small points and I have seen a larger knife blade made from it too.
