Within the last 5 years or so I have done quite a bit of scavenging for native american stuff. Living in Mercer County it seems awfully difficult to locate such things on a whim and fishing constantly I more times than not come home with a stiff neck trying to do so. Anyhow, I made a sifting box and my 5 yr old son is a full fledged crick stomper, so when we're out I spend a lot of time sifting through gravel bars and such. Besides finding many fossilized teeth and other unkown items, ive brought home several, from different locations, nickel sized, button shaped pieces with a center hole in them. At first I thought that this may be just an anomaly since in the locations I havent found anything but the occasional, possible, flint knappings. Since Ive located more than a few I feel that its probably something handmade. Just curious what anyone experienced thinks based off of the description. When I get a chance Im going to post pics of numerous suspect things that Ive found from PA and during military travels from here to California. A side note on the sifting box. I spent a couple hours sifting underneath a glacial boulder outcroping about a month ago and found...im gonna say close to 2 ft under the material..a perfectly round fire pit with burn markings on the centers of the stones. Of course there was no reason to disturb it so I covered it up, but thought it was pretty cool. Kudos to whoever put this categlory on HPA.
