Using Google Earth and Other Maps
November 2012 by Chris RalphLast month, one of our readers requested an article regarding the possible use of Google Earth for prospecting research. It was a good idea, so here it is.
Plumas has been historically rich in gold because of its favorable geology. The Melones Fault trends north-south through the county and many rich gold-bearing districts lie along its course.
On our last trip, we brought ropes and went down the first waterfall forty vertical feet, only to be confronted by a second, sixty-foot-high, overhanging waterfall that emptied into a slot canyon.
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
This year was a test. We had never done anything like this before, yet we grossed $30,000 in the short time we had to mine.
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
