I'm gonna vote the Raven:
A raven… The Raven, as the One that shows you the Way, kind. And, He has all your instructions to be followed (as per map) on His beak, between the “hair line” and the pointed-directional beak.
“wise is the one that goes to/through the ‘eye of the needle’ and find the square cross”………….He’s saying.
He also says, the Cross you’re looking for is not in plain sight. It’s imbedded in something, or under something. You may need to “scratch” it out.
The MAP, shows TWO different cache sites. The “key” is to find the “Cross” and the locations are obvious as per Cross doted locations, either NW and SE, or UP/Down on top of each other with a HEAVY slab or rock between them, as chamber divider. (3+ people need to roll/move away a big rock or slab)
All these ‘readings’ will have to be verified in the field, if they still ‘apply’ as accurate, since they have been a lot of “foot traffic” in the area since the original ‘builders’ and artists have left their mark.
Note: 1)…the Eye of the Needle, usually refers to a tight squeeze to a cave entry point, or another tight squeeze within the cave…………..if it has a fake/false double wall, of some sort. (check for patch marks around the edges of Back wall, and/or others)
Note:2)….the Cross, could also be a manipulated bunch of trees and/or their Roots, close to the surface but concealed under heavy rotten vegetation. (imbedded)
A picture of the cave’s floor will have to be “carefully looked upon” even if no apparent signs/marks on them. (eye of the needle….kind of look?)
The rest will have to be examined carefully step by step, …on site and compared with their instructions that will become more and more obvious, as you’ll go in depth.
(p.s. the raven has all the lingo of the Map on his head and body. Their individual location is what you must take in consideration,….when you’all figure the next move)
