From Radio Shack to Riches: An Amateur’s Lucky Strike
The story behind this golden goliath reads like a treasure hunter’s fairy tale, set in the unforgiving Sonoran Desert of Mexico. In 1989, near the town of Caborca, close to the Gran Desierto de Altar in Sonora, an ordinary man with an extraordinary dream began his quest.
Armed with nothing but an entry-level metal detector from Radio Shack and a pocketful of hope, he set out into a landscape where daytime temperatures often soar above 125°F (52°C). This harsh environment, just 60 miles east of the Sea of Cortez and 70 miles south of Arizona, had long been the subject of treasure legends.
For days, our intrepid explorer swung his detector under the scorching sun, following a careful grid pattern. His earphones chirped occasionally, usually signaling scrap iron or old bullets. But persistence paid off. One fateful day, the ‘beep’ sounded different.
As he dug deeper, the nugget kept growing. What started as a glimmer of hope turned into a 10¾-inch high, 7¼-inch wide behemoth of solid gold. Its distinctive boot shape, reminiscent of a conquistador’s footwear, would inspire its name: The Boot of Cortez.
