Allright Dr00bie, I'll jump in here and give you my 2cents worth.
Looks like your buddy built his house on top of an early Archaic
site which dates to about 6-9000 BC.
Point names differ from area to area, which is unfortunate, but you know how it is. You can't put three different archs in a room together and expect to get a consensus.
Anyway, the point you are asking about is a good question.
I would call it a Kirk, as I would the one in the top left corner.
The one in the top left is classic Kirk, well made of high quality
material. ( I like the change in the material as it goes toward the point. Looks like it flows into a breccia?)
Your Kirk on the right looks different but not enough to knock it out of the same ballpark. The differences could be because of the difference in material. It could be a harder material to work, so it is alittle more bulbous and the base not as well defined. What if
those Kirk guys were sitting around that spot, like you and your buddy do today, and one of them said,' I wonder how this rock from the next hill over works? It's a lot closer than the good stuff
two days walk away.' So he tries it, and then he and his buddy
have a good laugh about how it turned out, and he tosses it down there where you found it, never used.
That might be why it was still whole?
Anyway, I know all you wanted to know was what kind it is.
I'd have to throw it in with the Kirks at about 7000 BC. The oldest
one in the picture is the top row middle. My guess is that is a Palmer which dates to around 8000 BC., the predecessor of Kirk.
The two in the middle row left of the quarter are the same. The far left one was obviously broken at some time and resharpened
into the point you have there. If they are not the same type, they are real close in age which I would guess to be around
2000 BC.
Note: All the above is just my opinion and other different opinions
are more than welcome.
