Good thinking, except.......First you dream up a treasure, then you reverse engineer the treasure map. A treasure who's makeup is unnamed and not even hinted at, makes the whole thing more enticing.
Now if someone who knows every treasure tale of the Superstitions and every inch of the range helps you engineer the drawing to create on the Stone Maps, you have created a palpable treasure legend. For me, that trail goes right through many of those stories, and right through the middle of the Harry LaFrance cave of gold bars.
Going a bit deeper, it has Storm's rich piece of "float" ore in Old West Boulder, Adolph Ruth's last camp and 1/2 dozen or so other stories/legends. I have to admit I've left out the stories that surround Black Top, of which there are many.
It's, basically, a target rich environment.
