Thanks, Mastodonian Mike! Mid-peninsula? Well done by dad the geologist!
If I can tax your patience further, now I’m worried (it never stops) about what looks like some sort of rust/chem reaction/biological agent I see between the ivory and the ... ... dang it! What’s the word for the metal piece that is recessed into the ivory and holds the piece of ivory in place. I want to say escargot! Anyway, I can see some sort of green ring. Pictures (attached) were a challenge. Be kind.
Thank you!
