How many Motley or Kay have you found there in Ohio? How many of the types have you personally studied? I would wager that you are less than familiar with them, and that's ok. You are contradicting yourself in stating you aren't going by outline, when the "shape" is pretty much all you're bringing to the table in identification. LOOK at the publications you're relying on, it makes me sick to my stomach how they (especially O-street) are so full of misinformation. TRUE MOTLEY (do the research) are Poverty Point. Now, where is the Poverty Point culture and what are the identifiers? Now do a comparative study of Kay and several others.
As far as "large corner notches,expanding stem,triangular blade,flaking styles" - do you want me to name 10 other points that can describe? Let's be real here.
The fact is that Motley is just one of the MANY generic types that gets slung around everywhere. Almost no matter where the type is from, people still erroneously associate other points with them. Other types that get misidentified as occurring just about everywhere are Kirk, Big Sandy, Gary, Eden, Scottsbluff, Dovetail, Madison, Scallorn,..etc..etc. I could write a book on the typology errors that are commonplace with collectors.
For instance: The true madison point was named for belonging to a Cahokia toolkit, perhaps a preform. In other words, the eastern triangles called "Madison", aren't Madison at all. Or, "Tupelo" aren't Turkeytail at all, or there's no such thing as an Agee "A"? Or, there's no such point style as "Albertson"? Anyways, you get the drift.
Look, I'm not posting this to try to demean you. Believe it or not, I was trying to be of educational benefit to you. I rarely post unless I feel I can make a contribution somewhere. I respect your opinion and you have every right to it. I'm not going to argue with you on the subject, it's not worth it to me. However, I really do wish you would expand the research to more established references. There is no such thing as an instant-expert guide, and you will find that publications are generally only the authors opinions and subject to flaw. Some of them far greater than others.
I'll be the first to admit that I am NOT a good teacher, as I don't have the patience for it. But, I still have the Achilles heel of wanting to educate where possible.
