Lost gold Blanco NM

[Josh640]

Hello there! I'm new to the site and I'm at a spot that I don't understand what I'm looking at as far as signs and symbols. From what I can tell this location is on the old Spanish trail. I was looking for a lost loot that was supposed to be buried around this location. Upon investigation it definitely seems I have found trail monuments. Maybe a few of you can look at the pictures and maybe give me some insight on what it is and what to do from here.

Lidar would help read some of those symbols, maybe they give a date to watch where the sun shines through that hole to the treasure? Newer ipads have LiDAR built in.
