Fortymile, Alaska Prospecting Adventure
August 2013 by Steve HerschbachSome creeks have nuggets, while others, particulary the rivers, nothing but fine gold.

Looking around, I could tell that this was an old hand-digging. As I walked around the perimeter of the digging I could see shovel and pick marks scratched on the clean, hard clay and bedrock.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
Rocks and minerals associated with clay seam gold deposits in southern Oregon are often in sedimentary rock units at least partially metamorphosed into argillite. They are also associated with mafic volcanic rocks, basalts and gabbro that...
There are not a lot of tools needed to get out and take advantage of the situation. Other than my wetsuit, I typically travel light with a gold pan, maybe a pry bar and a few crevice cleaning tools.
