I hope its not contagious.
I thought that at first too. I went back to this spot yesterday. The 1721 is prominent in that rock. Those other shapes are in the Spanish symbol books.
Its not like I want to go dig into a sealed Spanish mine. I mean, 300+ year old timbers, buildup of gases, potential collapses, the most stable part is probably rocks in the opening. The only thing safer would be to wrap myself in rattlesnakes as a fashion statement while digging. LOL.
Thanks for taking a look at it.
