I'd like to find some destinations in the Pacific Northwest (US) for panning or gathering precious metals or gems, preferably without requiring non-trivial effort to gain access to. This is meant as a recreational thing with a small group of people.
I am not from around your area, but prospecting has always been an interest of mine.
This article from Nature of the NorthWest has many links pertaining to the rules, regulations and locations of the gold-panning areas in the Pacific Northwest.
I hope this helps.
