Ray Martin

Ray Martin (also given as Roy Martin) was a named partner of G. Warren Shufelt and Rex I. McCreery in an abortive 1933 mining venture at Fort Moore Hill in Los Angeles, California, the plan based on an ancient sheepskin map and a "radio x-ray" device that allegedly mapped underground tunnels filled with gold.

With all the romantic marking of treasure maps, crosses, mysterious symbols and figures, the ancient scroll was consulted from time to time as the workmen bored into the sidewall of the shaft. The radio gold-finding machine invented by Shufelt was brought into requisition later in the day and through its findings an approximate location was set where the tunnel should be found."

There are at least sixteen places where gold is buried or concealed in vaults."
