You serious? Sure, there is gold in most western states, I believe. There mayb be some public areas you can pan in both the desert dry panning and some of the rivers there, but am not sure.
FWIW I don´t pan for gold, I go for gemstones sometimes, and I have dug out topaz in Utah, plus there are less valuable stones to dig, and fossils and the like. Sure wouldn´t mind finding some red beryl there, they got that too and it is extremely rare and valuable.
