Prospecting & Detecting
Trash! A Hindrance Or Hot Spot For Hidden Gold?
March 2018 by Ray Mills

The names attached to these areas came about from many sources. Many are easy to see why the name was given while others had a more contrasting note to them.
The Gold of Plumas de Oro
Their rewards were far better than they had anticipated, resulting in one of the best clean-ups they had ever seen.
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.
Prospecting Knowledge -- Pass It On!
