There was a Clovis point I believe found in two different levels and what struck me when I was seeing pics and reading about it was the patina. It was two different colors. I'll try to find it. It was cool looking.
That's really cool!
That almost tells me that it was collected and curated as we do with artifacts..then it became one again.
Mabey it was taken back to the spot it was found on purpose.
NEAT!
