The Downieville Gold District
January 2011
Many locals are just waiting for California to allow dredging once more, especially with the current gold prices. There are still plenty of good opportunities for prospectors in this area, just as it has been for so many years.

Rattler's Gold

When we look ahead into 2011, we see continuing troubles such as those listed earlier, which will force the public to question the effectiveness of the entire concept of economic strength and vitality through government interventions.
