I wanted to reiterate something again since so many people seem to think the markers at/close to these treasure sites help locate/find the treasure entrance.
Nothing could be further from the truth, the markers are scattered near the entrances on purpose to lead people away from the treasure entrance. (The markers that are further out do get you close to the treasure area many times by looking towards the treasure area but I am not talking about these markers I am talking about the ones within a hundred feet of the entrances)
This is why the Crisscross Spot is Hidden Information you see all these markers but without knowing that different ones align to an Invisible spot (a Crisscross Spot) you really don't know how to use the markers which is not shown to you on any of the markers.
They also made secret entrances at some of the large caches (not just the main entrance) and again only the people who worked/made it had that secret entrance knowledge either on a map or just known.
So the idea here is that they (the Catholics) did use the markers when they came back to retrieve the treasure but they would either just know where to go from the markers or had a map (Here is an example: Go 30 Degrees at 27.5 feet from the Crisscross spot) First you would need to know what a crisscross spot is and how to find one which is not shown in the field on any of the markers, then you would need the 30 degrees at 27.5 feet which again is not shown at the crisscross spot or on any of the markers. This is why it is so important to Catch an Aura to get even remotely close to the treasure.
What I am trying to say here is the markers are not really as straight forward as that turtle is looking at the entrance, I have heard people say the Turtle looks right at the entrance as well as a Owl looks right at the entrance, so if this is true then there really isn't any need for an Invisible Crisscross Spot aligned with at least three alignments (which I have found multiple times at auras), or a 130 foot Triangle only marked at 2 points (which I have found a couple times as well as Calvin Keys and Kenworthy found) or a 144 Foot Cross Marked at 2 points (also found on Oak Island), so go ahead and try to dig out from a turtle or an owl and see if you hit an entrance, who knows maybe you will get lucky.
