WOW, that hard rock Ax stands out like a Texas Andice in a bird point frame. Very nice.
Is there a book similar to the "overstreet" reference and $$ book that deals with the hard stone, pottery and ancient copper artifacts [ non flint items ] covering your area and East & NE ?

Thanks for comments asfar as ref. books Artifacts of the midwest by Lar Hothem is a good book don't know of any $$ guides most of them are overvalued for us common folk!
