Graham cave??

[jpitt1970]

Found this on my Archaic site Sunday. The base is ground and there appears to be a slight flute on one side. Looks like a Graham Cave to me, what do you guys make of it?

posibly,if so its just a preform as all i see is percussion flaking on it,or maybe it could be a cumberland that they shaped and didnt finish for some reason or another
