Reall truth : This is what makes all treasure legends so easy to fall for : Is that they are always built around real names, dates, and events. To which we add a treasure. Ie.: None of them ever started with : "Once upon a time", eh ?
And the believers will then say : "It's only a matter of sorting fact from fiction". But what that fails to take into account is: If there's no treasure, then IT DOESN'T MATTER how much of the rest of the story is true (names, dates, events). If there isn't a treasure, then : THERE ISN'T A TREASURE !
Prospexican, excuse me for my skepticism, but : Do not get caught up in the superstition of : Symbols in the landscape. To "read into random landscape features". Eg.: squiggly lines seen on a tree, etc.... Or the odd uncanny symmetrical placement of boulders in the area, etc...
When we are totally honest : You can ALWAYS find "uncanny " things or "symbols" everywhere. Eg.: If you lie on your back and stare at passing clouds long enough, you will eventually see the shape of a bunny, an angel, a clown, a big-dipper, and so forth. All of which are meaningless and random.
And for sure when someone goes to *hide* a treasure, they THEN make a map that they circulate. So that others can "find" the treasure that they just "hid", right ?
