Gold of Plumas County
November 2010 by Frank Lorey IIIPlumas County has a rich heritage of gold mining, much of it from placer deposits that can still be searched and panned today. Being at the far northern end of California’s famed Mother Lode, it is quite often overlooked by those searching for gold today—really a well-kept secret after all of these years!
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
The hair stood up on the back of my neck when I saw this, especially the nice patches of wash in the bottoms of the gullies, a sure sign of an auriferous source being nearby.
A few quick calculations show that approximately 11 tons of gold are lost each year just in the manufacture of new cell phones.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
In 1877, a prospector named Ed Schieffelin discovered silver in “the middle of nowhere” and staked two claims: “Tumbstone” and “Graveyard.” Soon a town and mining district were organized and acquired the name “Tombstone” after making a spelling correction.
Gold has always been noted to have an affinity for quartz to such a degree prospectors almost always dig on quartz veins in a search for the precious metal.
Unfortunately for us mortal humans, we have a poor perspective on geologic time. When we look at a landscape such as a stream valley, we see it only in two, or at the most, three dimensions. We have poor comprehension of the valley’s fourth and most important dimension—time.
