My hunch was that the gold is coming down the apron, falling off to both sides and into both gulches. I say that because the gold we found previously has the same characteristics and color across the entire area.
The mysteries of this spot were only just starting to develop. There is nothing but very bland granite-type rocks here, meaning no bold, favorable indicators.
One of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
Mike and Machael dug in just downriver of that boulder pile and right away found good color and a few small pickers.
When I teach people about finding gold, I often explain that it is helpful to think of any river or stream that carries gold as being something like a sluice box.
We decided to run a detector over each piece. If we got a decent signal we placed the piece into a high-grade pile and the rest went into another pile to be worked on later. This high-grade pile wasn’t that large—maybe 25 pounds...
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.
Most dry washers have a feed rate adjustment. It needs to be set so that the material flows evenly over the riffles and does not bury them.
