Hey Ken! Interesting point! Was this a surface find or was it dug? Some information to consider if it was a surface find. I am a Scout leader and have bought reproduction points, similar looking, in bulk over the years to use as crafts or merit badge purposes. Many of the repros I have purchased coming out of Mexico closely resemble yours in shape and design, though I have never seen a white one. Many are made on large flakes and there is a curvature to the point (as it appears on your picture). Depending on the supplier, some are much better made than others.
Anyway, this is just an friendly observation!
Hope yours is genuine and a new point type to the area!
I too questioned whether it was a recently napped point, its not flint either, softer stone, but not Limestone. It was a surface find by my freind on my property in Boerne with me in 06. Had greater than twenty acres of undisturbed area in River Mountain Ranch residential development,North of Boerne near the Guadalupe and some Spring complexes in the vicinty. Not much traffic out there at all.
Thanks for everyones comments, will search up the referenced types, I would like to find something like that diggin, but all I find so far is broken and rough Points. Thanks Again, Ken
