I'm told there is an artifact show coming here in april, I plan on taking a few things there to see what they say.greg-rocks said:does it have any polished areas,does it have any abuse areas where it looks like they used it?is it pecked all over.thats what you are looking for.cant tell from your pic.rivers may shape stones,but they dont peck them into shape.
