Just for curiosity sake I started noticing the material looks a lot like Tennessee's blue material so I checked out some Tennessee points... it looks like it could be a Brewerton eared triangle since your so far up in the state.
..... Or not.....
I will check........I believe you nailed that one. I guess it was just a fluke on the pottery being near it. Its amazing how many different periods used the same sections of land. This point dates 6000-4000 B.P.
