I found this one coming back to my truck thinking I had been skunked again. A nice surprise. I am leaning towards an Intrusive Mound point? It's smaller, about 1 1/2 inches.
Nice find, great insitu pic. I think Intrusive Mound points are more corner notched, this appears more of a side notch, or expanding stemmed point. Maybe a Susquehanna Broadspear?
