Arrowhead - Native American Bird Point

This was craftsmanship at its finest. It was so small (the size as the tip of a key) I don't know how a person could chip it so perfectly. It was see through except for the little fleck of black on the bottom that was stuck inside. and it seemed like it had broke just a little bit at the tip. But besides that it had overcome the test of time. I left it there hoping it could keep doing so and maybe just maybe. some day. Someone would come across it to appreciate it the same way I did. What kind of crazy things have you guys stumbled across on your adventures?
