That is an awesome find Rock! I love the material and the form.
At first glance it does make one consider Paleo, but if I had found it up here in the mid Atlantic, I might consider it a cross between a Fox Creek (aka . Steubenville), and a Jacks Reef Pentagonal. It is hard to tell from the photos alone, but the base does not appear to be heavily ground? Did this come from the sites where you are finding predominantly woodland era finds, or is this from a new site without previous finds with which to compare context?
You are on a roll, and I am anxious to see what else you find. HH
