The hope was that a bit of the gold from that famous old pocket mine had worked its way down the slope of the hill and into the gravels Pat and his crew were planning to mine.
I Just Tripped Over A Nugget
I metal detected a number of years before I saw my first nugget peeking out from the dirt before I had scraped or dug for it. This one was in the steep sidewall of a narrow, but deep drywash.
Following the Clues
It took me awhile before I finally got a nice mellow signal. My nugget turned out to weigh in about two dwt (pennyweight). Over the next few hours, we all picked up a few more nuggets apiece.
Border Silver
There is a sizable area that straddles the U.S.-Mexico border where native silver occurs in shear zones at relatively shallow depths. The district is in the low but rugged Pajarito Mountains, the highest point of which is 5,838 feet at Cerro Ruido, on the Mexican side. The deceptively rough terrain forced the first border surveyors, in 1855, to kill several mules and horses because of their injuries.
