Weathering, Erosion and Placers
April 2017 by Chris RalphThe big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
These gritty clay lines were only a quarter of an inch up to three inches wide. Once the line had been laid out, they would look at the wall of gritty clay material and seek more indicators.
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
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.
Down around 10 or 12 inches I hit a large cobble that appeared to be one type of hot rock for this area. I thought bad things about the new technology until I checked the rock.
What do you do when you’ve located a promising deposit of gold or gemstones, but it’s trapped in solid rock?
Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.
