Detecting Nuggets—Overcoming New Challenges
September 2015 by Steve HerschbachDepth is not an issue unless the site is thoroughly cleaned of shallow trash, and it is far easier to isolate and remove targets using a small coil in a target rich location.
There may be lots of smaller gold I cannot hear with a detector, but it looks just fine in my pan once it is out of the crevice.
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.
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.

In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access.
