>>676010Look into getting a membership with the Gold Prospector's Association of America. Part of the benefit of membership is that have 100s of private claims across the country that members can access. An added benefit of membership is their mining guide publication that tells you about each claim, what to expect, and turn-by-turn directions. It also lists all the public places in the US you can prospect. You also get a periodic newspaper that updates you with newly added claims.
Here's the link about memberships:
