Nice Banner! I do the same thing with bottles, arrowheads or anything else I find and REALLY like! It takes a good week or so of packing it around with you to really KNOW for sure if there is any damage... or if it's PERFECT!!! LOL
I feel your pain guys. I've been in hibernation. It's warmed up a little to around 30 and it feels balmy! I sure could use a dig. I'm dreaming about finding bottles. In the meantime, I just read about them and look at the ones I have. Joe and the gang were talking about a possible outing this weekend to explore. All I know is the place has an old abandoned truck. I'll be looking in it for some old coins. I keep thinking and thinking about some old spots in my hometown. I wish I could get back there now that I know more.
Like some of the other guys said, it's a bannerstone, which in my humble opinion is an evolution of the atlatl weight. I can't see using one this refined and with that much work as an actual working atlatl weight, but more than likely as part of a presentation-grade atlatl for an important tribe member. An analogy would be the pocketknife you carry around all day, and the engraved collector's knife that's for display only. I hope I'm making sense here.
