The Golden Triangle of Sonora, Mexico
May 2001 by Edgar B. Heylmun, PhDThe “Golden Triangle” dry placer district in Sonora, Mexico, lies some 80 to 100 miles south of the border. It is in desert terrain at elevations between 1,900 and 2,300 feet above sea level.
Many people, mostly New Mexico Native Americans, but including this miner, wear turquoise from the first mine in America. I took my blue stones from the old mine by hand labor, underground, a half century ago.
Since the 18th century, collectors, geologists and archaeologists have sought the answer to a frustrating mystery: The ancient Olmecs fashioned statues out of striking blue-green jade, but the stone itself was nowhere to be found in the Americas.
Face-to-face meetings in Washington, DC, with Trump administration officials and members of Congress are still on hold due to the coronavirus, but Public Lands for the People is continuing to work on mining-related issues via phone and email.
