Back to reality....
Y'all keep saying that stack of huge rocks is man made. Have any of you even considered the physics involved with raising multi-ton boulders up high and then carefully placing them in exactly the right spot? You'd also need to carve a perfect before stacking the stones. I've heard folks claim entire mountainsides (hundreds or thousands of cubic yards) were carved into animal shapes so that the signs could be seen from a distance. That said, the spire in the photo (or any recognizable landmark), even natural, does make a nice target to search for. A simple confirmation carving somewhere on the stone would then alert the searcher he's found what he's looking for.
Don't believe they had any crane rentals back then, so they would have had to build a large superstructure with very big beams to haul those boulders up that high, plus the manpower to build it. Then, post construction, they would have had to disassemble it all and haul it all away so people 300 years in the future couldn't figure out how they did it.
All of this discussion is irrelevant if someone does not locate a treasure in the immediate area. How many people are out searching? Not many these days. The clues won't help unless one has them all and knows how to use them. First thing I would do is carefully take coordinates for all potential clues found. Or, if not too far separated, compass/distance measurement (more accurate than recreational GPS's). Then plot up on a map and see if a pattern emerges. No use speculating, because I imagine the OP is only posting part of his story, so what we say here can only be just general common sense.
(IF the US Gov't is reading this, you should consider giving jobs in the Conspiracy Dept. to some of these people. They're really good at it.)
