Yes I have found several like that. I found one point up north that looked like a San Patrice. Stumped the experts on the artifact forum I used to frequent. Arrowheads sure are fun to find!! An expert I know who used to write for Indian Artifact Magazine suggested there was a lot more trading going on than what others believed. I also think about the people making these points. I think there was a lot of variation in points based on maker, maker’s age and skill leve (kid vs adult), etc. just my thoughts!
