With nuggets like that there. I would sell my soul, to get a Cat 225 Excavator and/or Big cat bulldozer to reopen & expose that kind of paydirt. . Years back in the Sierra Nevada’s near the Feather river I found old drift mine placer workings high up, near the top of a Mtn. Old blue & red iron oxide cemented gravel channel was buried under about 60 to 120 feet of lava cap hard rock. Erosion had exposed the old channel in a few small spots here & there. Anywhere it was exposed, there were hand stacked cobble piles from the gold rush era, where old timers worked the exposed gravels. Recovery methods were poor, as the was no water there, that high up. Several large cobble dumps I would judge by their size went into the old channel gravel 100 feet. Sadly every portal area was sloughed in or caved. Found an old wagon trail that was so overgrown, you could barely recognize it. It led to a small creek at a lower elevation that was the nearest running water. Apparently, old timers hauled dry pay dirt type gravel to the creek to wash it. Found a few “coyote” holes dug into the hillside from depression era hand mining. There was a lot of fine gold in the tailings. Enough to get me excited anyway. My schedule ran me out of there, as I had other business to take care of. Told a metal detecting guy about the place, he went next spring & found a handful of little “pickers” in the dry wash ravines. But the hike up to it was to much for his age & condition, so he only made that one trip Always wanted to go back & do some serious exploration there. Sadly, the way things are in California, I gave up on the idea. As trying to permit any heavy equipment work there, would take longer than the time I have left.
