Big Rock Gold
August 2012 by Tom LeftwichFran, and I had made a practice of turning big boulders in gold producing areas to find some great rewards. Sometimes it was slow and frustrating, but in the end “We got the gold!”
I remember in the couple of years after that 1997 flood, prospectors around California did very well, taking ounces of gold from places that had not yielded any gold for years before that.
In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
During this trip we found enough gold to make us want to come back, even with the punishment of a very long, tough hike.
This article is intended to try to help someone who is breaking into gold detecting and using a pulse induction (PI) detector.
Problems finding gold with a detector
Prospectors who specialize in nugget detecting are especially interested in this special desert type, as it produces nuggets that are close to the surface of the ground and therefore more suitable to be found with a detector.
