The Peralta stones

In 1949 a set of carved stone tablets surfaced, covered in crosses, trails and Spanish phrases, claimed to be a map to the Peralta family mines in the Superstitions. Museums have held them, experts have called them nineteenth century or nineteen-forties depending on the decade, and treasure hunters still line their carvings up against the skyline. Read them as the artifact mystery they are: nobody has ever produced the mine.
