Prospecting & Detecting
Finding Streams of Gold
September 2014 by Ray Mills
Without knowing or even thinking about it, I had put together a map that showed me a pattern of the ancient Sacramento River channel. I also had a distinct picture of where the ancient channels of several other creeks and rivers were running.
Just One More Time
We chose this particular area because an old channel had run here at one point and had been heavily worked on top of a mountain hilltop. Erosion patterns cut deeply on each side, leaving the channel exposed. The erosion cut sharply, dropping into ravines far below.
Potholes and Other Bedrock Traps
Potholes 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.
Moore Creek, Alaska—Then and Now
The gold was very chunky and much of it had quartz attached. Even back then I knew that the gold was very close to its source.
Prospecting With a Detector: Lessons Learned
That is the course and intention for this article—to wander through some of the lessons I have learned in my thirty-two years of metal detecting and prospecting.
Detecting Alluvial Bench Deposits
