That particular map came from the Noss family, possibly an original possession of Milton Noss himself. Noss of course was a serial liar, notorious con man, violent offender and textbook sociopath. Just sayin'.
Until someone can manage to scientifically test any of these "almacen" treasure maps in a forensic lab in an attempt to establish their provenance, we have to ask ourselves some mighty penetrating questions about them - questions that many of us probably would prefer to ignore. For starters, if any of these documents are genuine, just how in the hell did such ostensibly monumentally valuable charts manage to slip away from their creators, find their ways into the hands of other parties, then later find their way to the general public? Same questions apply even if these things are modern day copies of older originals - how is it that guys like you, me and many others have them in our sweaty hands? Were we just born lucky?
Human nature never changes. Those who preceded us were not stupid, naive or careless. If the caches exist, riches of this magnitude were/are protected with numerous layers of security, IMO. One of the most effective methods of securing a valuable cache is to take advantage of human nature and allow disinformation to "leak" its location. I happen to believe there is likely some truth behind the cache legends - what, I don't know, but I suspect that if they're real, they remain safely hidden. Of course, these "treasure maps" could be complete hoaxes created by clever people with a good knowledge of history and cartography too. On the other hand, they also could simply be "half real" - enough good information to convince the curious, but not enough to direct them to the prize. Go west, young man. Ooops, perhaps I should have said east.
To me, the real curiosities are: who hid the goods, and if it's still hidden, why? Lost? Waiting?
at least 90% of these treasure maps are fake...and the 10% that are the real deal are only good to the person that made it...they didnt make a map so someone on a treasure forum could find their treasure 100 years later..they made the map so THEY could get back to the treasure
