There are a variety of topos on the market. I have used many of them, they are so important to the hobby.
The La Esmeralda Church Treasure - is several tons of gold bars, as well as silver and gold church relics. It is believed to be buried approximately six miles southwest of the old San Xavier del Bac Mission. The treasure may be in a cave along the south ridge of the Santa Catalina Mountains.
The Fort Huachuca Treasure - Somewhere in the Huachuca Canyon, on the Fort Huachuca Military Reservation, is a reported treasure worth more than $60 million. The treasure consists of hundreds of gold bars weighing 50 pounds each. Apparently, a Mexican bandit, Juan Estrada, buried the treasure somewhere between Bisbee and Nogales. There is a story that states in 1941, Robert Jones, who was stationed at the base fell into a hole and located the treasure. Jones was reported to have taken a few gold bars, and then covered the hole, not telling anyone. In 1959, Jones received permission from the U.S. government to recover the gold. However, Jones was unable to re-locate the massive treasure.
The Telegraph Pass Buried Treasure - in 1870, approximately $50,000 in gold and jewelry was placed into an iron kettle, and buried near Telegraph Pass. Apparently the treasure was buried in a campsite, near a small butte, on the east side, below Montezuma’s Head, on the southern end of the Estrella Mountains.
The Sunlit Cave Treasure - several tons of Spanish gold and silver bullion is buried in a cave on the Arizona side of the Colorado River, approximately fifteen to twenty miles south of Ehrenberg.
Anytime you are going on to private property be sure to ask for permission. If you are venturing on to State or Federal lands you should know the laws of that State.
Understand The Antiquities Act of 1906
Good luck! And have fun in your search for buried treasure in Arizona.
