The Mexican Gold Belt
January 2006
Mexico is a large country, much larger than the state of Alaska. It is almost as long as the US is wide. It has climates that range from tropical rainforests in the south to barren deserts in the north. The Sierra Madre is a forested plateau that reaches elevations in excess of 10,000 feet. It parallels the west coast of the country.

The Lost Silver Triangle of the Sierra Madre—Conclusion: Tayopa, Guaynopa, and Guaynopita
July 2008
Lieutenant Henry O. Flipper might well have been correct about the “Santa Fe de Rodríquez” being the name of what is now called Guaynopa. However, an Indian named Agustín de la Cruz, who was associated with Cristóbal Rodríquez, is credited with discovering the mine in 1741. It is probable that the Spanish settlement had indeed been found because of its rather extensive ruins.
