Nice'ns! Overall, the stone surface looks natural to me; however, I think that one could still be an artifact. Maybe a grinding, abrading or smoothing tool IMO. Could have been worn like a pendant also. I would have picked it up anyway.
Any chance of getting a pic of your creek? Just make sure there are no land marks showing so nobody will know where it is at. Also do you ever find any pottery?
Hey Rock.I got my April issue of Central states archaeology journal today. There is a article entitled "A Virginia Snake Head Pipe" by James E Maus,Advance North Carolina.Weren't you interested in a upcoming pipe article a few months back?
