A single pamphlet published in 1885, entitled "The Beale Papers", is the only source of this story. The treasure was said to have been obtained by an American named Thomas J. Beale in the early 1800s, from a mine to the north of Nuevo México (New Mexico), at that time in the Spanish province of Santa Fe de Nuevo México (an area that today would most likely be part of Colorado). According to the pamphlet, Beale was the leader of a group of 30 gentlemen adventurers from Virginia who stumbled upon the rich mine of gold and silver while hunting buffalo. They spent 18 months mining thousands of pounds of precious metals, which they then charged Beale with transporting to Virginia and burying in a secure location. After Beale made multiple trips to stock the hiding place, he then encrypted three messages: the location, a description of the treasure, and the names of its owners and their relatives. The treasure location is traditionally linked to Montvale in Bedford County, Virginia.
