I have been looking for American Indian Native stone artifacts sin Michigan since I was six. Now late 50s. Fascinating hobby and free except for your priceless time out looking and good exercise to boot. I have over a hundred different arrowheads, spearheads, scrapers, celts, and a large handaxe, plus many pottery fragments from local clay deposits. I consider my self an amateur archeologist; an Indianapolis Jones wannabe.
Nice hobby.......go for it.
