Any idea on the metal object in the last of the photos? It appears to be copper ......goin by the green tarnish. Kasey found it bout 8" to 10" down in midden ....seems to have been there a very long time. Points came from the honeyhole, had to change it up after getting skunked last weekend at the Kerrville mound. I got lucky and ended up with the killer of the day....enjoy!
Another interesting report, well done. Seems you might be in the Pedernales family part of the camp grounds. Not given a closeup special pic as the "find of the day " but that Perd blade is really classic....last pic middle, one side completely worked down.
No idea on the copper ( bronze ? ) find but it's something better than farm machinery. If it was mine I would clean it with an electrolosis coin cleaner ( Googled " COIN CLEANERS ", Harbor freight has an ULTRASONIC cleaner. )
maybe it has some scribing under the patina. A real surprise find.
