Potholes and Other Bedrock Traps
September 2012 by Jim HalloranPotholes in bedrock can trap placer minerals and even be glory holes. They are, at least, interesting geologic phenomena, and at best, a treasure trove of gold nuggets.
The signal I was hearing was coming from a vertical bedrock crack on the bank of the creek. I removed my backpack, took out my crevicing tools and started to clean out the crack when I saw a glint of gold.
Mike scored the best with a total of one-half ounce of gold nuggets. Tom, Brian and Greg each had pieces in the one and a half pennyweight range. The rest of us had small gold and nothing like these three.
This time we took the detectors. Roger had worked that spot very well and wanted to see if my new detector would uncover any gold he might have missed.
Wouldn’t it be great if you could know if there is gold in the ground without setting foot on the ground? Well you can, to a certain extent, if you can recognize mined ground from unmined.
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.
...we were able to pull out close to another 3+ ounces of small, angular Silver City gold. This also included several more small nuggets, pieces of wire gold and some quartz-gold pieces—not bad for 4 days with a small sluice.
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.
