Well, you found a good one, Neal.
That presentation by Billy, Dr. Oliver, is about the best, most concise, explanation of the typology and chronology
of North Carolina projectile points you are going to find.
He sure looks young in that picture. Reminds me of the good old days.
Anyway, before I digress all over the place, the really simple way to identify your projectile artifacts
is get a copy of the poster I'm posting below. This is of the one I have framed so I had to shoot thru glass.
I believe you can read it if you enlarge it a little and scroll around.
You'll find your Yadkin way up in the top right hand corner about 500-1000 AD.
That's why we call them "projectile points" instead of "arrowheads", because most are some sort of spear or dart point.
The bow and arrow didn't become widely used until the Badin point just below the Yadkin.
We will have to get a good picture of this poster and permanently afix it to the top of this category.
I thought we had all ready done that but I don't see it anywhere.
I believe you can buy the poster at the gift shop at the Natural History Museum downtown Raleigh.
If you want to do some real research on the subject there is only one book to start with, mentioned many times in earlier threads,
"The Formative Cultures of the Carolina Piedmont" by Joffre Coe.
Dr. Oliver did run an organization downtown called the Coe Foundation for Archaeological Research, Inc., or CFAR, where you used to be able to order this stuff from their online store
but I'm not sure what's going on with them now.
It's neat you found a Yadkin in Mine Creek. I have found signs of Woodland occupation all thru some of the older neighborhoods in Raleigh.
House Creek, Crabtree Creek, and now we can add Mine Creek.
I hope this picture of the poster works for now.
