Some of my favorite pieces from the mohawk river region.
How's that?
I think the rocks with holes are natural, the artifacts I think I see, have flaking in them.
The greyish colored rock, with a deep groove, just above the stone with two holes, looks like steatite or soapstone. As such, if that's the case, it's likely an artifact. Likely is even if not soapstone. But I am not sure what it might be. Gotta put my thinking cap on, lol....
