The Mexican Gold Belt
January 2006 by Edgar B. Heylmun, PhD

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.Additional articles that might interest you...

Drywashing for Eluvial Gold in the Desert—Using a Portable Drywasher and Hand Tools
February 2005
Often the gold being recovered by drywashing is too fine to be recovered by metal detecting. For every “detectable” nugget found, there could be hundreds of smaller flakes of non-detectable size. Thus, for those that “read the ground,” and snipe for areas of favorable placer concentration, drywashing will continue to be both an inexpensive...
