Brep, If I'd have known you were on my doorstep I would have come out to meet you..
If you can take closer pics of the ones you are referring too, I'll tell you.
I can tell you for sure you are hunting on an Archaic campsite. These finds are what I come across everyday.
Next time you're there let me know, if its not too far, I'll meet up with you, help you search, of course no matter what I find would be yours..
Looking at your pic, now I can't say for sure without seeing closer pics but, the black point might be a Kirk, which would be Early Archaic, the larger point with the point & base missing as the look of a Morrow mountain type, which is Late Archaic, so that tells you the campsite could have been occupied by Early-Late Archaic cultures but, I would need to see them closer. Also finding 1 point type doesn't necassarily mean its a Early or late site, could have just been dropped by a hunter, you know on their way through, so to establish this, you need to find more than one of each type.
But I can tell you without a doubt you have a camp site..Congrats.
Molly..
