In Oregon. Quite a bit of gold in the southwest corner of the state as well as up in the northeast corner. Some in the central part around John Day, and in the mid Willamette Valley from Salem down to Cottage Grove. Got several GPAA claims in the state as well as public areas that have been set aside. Some gold on the beaches, but have to work for it.
As far as rocks and gems, have sunstone in the southeast part, all kinds of obsidian from black through the various "sheens", silver and gold, rainbow, mahogany, and some snowflake. All kinds of petrified wood, agates and jaspers galore, thunder eggs in a couple of areas, some garnet.
World famous John Day Fossil Beds in the central part of the state.
