Very cool thread. I liked seeing all of the pictures. I haven't found anything walking around in the woods, etc., but in my early days spent a summer studying archaeology in Itasca, MN. A couple of really interesting artifacts that I found included a chalcedony awl that looked exactly like obsidian, a perfect specimen that had a small point on one side and a larger on the other. It was an amazing find for me, especially considering that the tool was used for making different size holes. The other was a copper awl that was not native to the area, which indicated that this tribe had either traded with tribes from the Lake Michigan area (where raw copper was to be found) or that their migration routes took them that far.

I love this stuff, thanks for sharing.
